+The INIT package is required by all but the standalone and self
+extracting archive packages. It contains the package command, support
+scripts, and utilities.  The package command installs binary packages,
+makes source packages, and generates new package tarballs.
+
+Source Package Installation Instructions:
+
+  (1) Do not install packages as root/super-user. Although some components may
+      have setuid executables, few must be owned by root. These are best
+      changed manually when the security implications are understood.
+  (2) Choose a package root directory and cd to it. This will be a local work
+      area for all packages.
+  (3) These instructions bypass the click to download package links on the
+      download site. If you already clicked, or if your system does not have
+      curl(1), hurl(1), lynx(1) or wget(1) then use the alternate instructions
+      for (3),(4),(5) in plan B below. Plan B installs the hurl(1)
+      script which works with ksh and modern bash. The top level URL is:
+		URL=http://www.research.att.com/sw/download
+  (4) If the bin/package script does not exist then run:
+		test -d bin || mkdir bin
+		url=$URL/package
+		(wget -O bin/package $url||curl -L $url||hurl $url) > bin/package
+		chmod +x bin/package
+  (5) Determine the list of package names you want from the download site, then
+      use the package(1) command to do the actual download:
+		bin/package authorize "NAME" password "PASSWORD" \
+			setup source $URL PACKAGE ...
+      (Refer to the AUTHORIZATION paragraph on the main download page for
+      NAME/PASSWORD details.)  This downloads the closure of the latest
+      source package(s); covered and up-to-date packages are not downloaded again unless
+      package force ... is specified. Package content is verified using md5sum.
+      If the package root will contain only one architecture then you can install in bin and
+      lib instead of arch/HOSTTYPE/bin and arch/HOSTTYPE/lib by running this
+      instead:
+		bin/package authorize "NAME" password "PASSWORD" \
+			flat setup source $URL PACKAGE ...
+      To update the same packages from the same URL run:
+		bin/package setup source
+  (6) Build and install; all generated files are placed under arch/HOSTTYPE
+      ($INSTALLROOT), where HOSTTYPE is the output of bin/package (with no
+      arguments.) name=value arguments are supported; CC and debug=1 (compile
+      with -g instead of -O) are likely candidates. The output is written to
+      the terminal and captured in $INSTALLROOT/lib/package/gen/make.out:
+		bin/package make
+  (7) List make results and interesting errors:
+		bin/package results
+      Run the regression tests:
+		bin/package test
+      List test results and errors:
+		bin/package results test
+  (8) The generated binaries are position independent, i.e., they do not
+      contain hard-coded paths. However, commands with related files, like
+      file(1) and nmake(1), require the path of the bin directory to be
+      exported in PATH.
+  (9) You can run the binaries directly from the package root, or you can
+      install them in a public root after you are satisfied with the make and
+      test actions (requires the AT&T nmake(1) command):
+		bin/package flat install DIRECTORY PACKAGE
+      This will install in DIRECTORY/bin and DIRECTORY/lib. If you want to
+      preserve the arch/HOSTTYPE hierarchy under DIRECTORY then omit the
+      flat argument. If you don't have nmake(1) then the following will do a
+      flat install:
+		cd $INSTALLROOT
+		cp -p -r bin lib include DIRECTORY
+  (10) To summarize, after the first time the download, build, and test cycle
+      for the latest source release is:
+		bin/package setup source
+		bin/package make
+		bin/package test
+
+Source Package Installation Instructions -- Plan B:
+
+  (3) Create the subdirectory lib/package/tgz and download all package archives
+      into that directory.
+  (4) If the bin/package script does not exist then manually read the INIT
+      source package:
+		gunzip < lib/package/tgz/INIT.YYYY-MM-DD.tgz | tar xvf -
+      Note that some browsers automatically unzip downloaded without warning.
+      If the gunzip fails try:
+		tar xvf - lib/package/tgz/INIT.YYYY-MM-DD.tgz
+      If your system does not have tar(1) or gunzip(1) then download the ratz
+      source package, compile it, and manually read the INIT
+      source package:
+		mkdir bin
+		cp lib/package/tgz/ratz.YYYY-MM-DD.c lib/package/tgz/ratz.c
+		cc -o bin/ratz lib/package/tgz/ratz.c
+		bin/ratz -lm < lib/package/tgz/INIT.YYYY-MM-DD.tgz
+  (5) Read all unread package archive(s):
+		bin/package read
+      Both source and binary packages will be read by this step.
+
+All recorded changes follow.

+
+Eclipse Public License - v 1.0
+
+   THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS ECLIPSE PUBLIC
+   LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION OF THE PROGRAM
+   CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
+
+   1. DEFINITIONS
+
+   "Contribution" means:
+
+   a)  in  the  case  of  the  initial  Contributor, the initial code and
+   documentation distributed under this Agreement, and
+
+   b) in the case of each subsequent Contributor:
+
+   i) changes to the Program, and
+
+   ii) additions to the Program;
+
+   where such changes and/or additions to the Program originate from and are
+   distributed by that particular Contributor. A Contribution 'originates' from
+   a Contributor if it was added to the Program by such Contributor itself or
+   anyone acting on such Contributor's behalf. Contributions do not include
+   additions  to  the Program which: (i) are separate modules of software
+   distributed  in  conjunction  with the Program under their own license
+   agreement, and (ii) are not derivative works of the Program.
+
+   "Contributor" means any person or entity that distributes the Program.
+
+   "Licensed Patents" mean patent claims licensable by a Contributor which are
+   necessarily infringed by the use or sale of its Contribution alone or when
+   combined with the Program.
+
+   "Program"  means the Contributions distributed in accordance with this
+   Agreement.
+
+   "Recipient" means anyone who receives the Program under this Agreement,
+   including all Contributors.
+
+   2. GRANT OF RIGHTS
+
+   a) Subject to the terms of this Agreement, each Contributor hereby grants
+   Recipient a non-exclusive, worldwide, royalty-free copyright license to
+   reproduce, prepare derivative works of, publicly display, publicly perform,
+   distribute and sublicense the Contribution of such Contributor, if any, and
+   such derivative works, in source code and object code form.
+
+   b) Subject to the terms of this Agreement, each Contributor hereby grants
+   Recipient a non-exclusive, worldwide, royalty-free patent license under
+   Licensed Patents to make, use, sell, offer to sell, import and otherwise
+   transfer the Contribution of such Contributor, if any, in source code and
+   object code form. This patent license shall apply to the combination of the
+   Contribution and the Program if, at the time the Contribution is added by
+   the Contributor, such addition of the Contribution causes such combination
+   to be covered by the Licensed Patents. The patent license shall not apply to
+   any other combinations which include the Contribution. No hardware per se is
+   licensed hereunder.
+
+   c) Recipient understands that although each Contributor grants the licenses
+   to its Contributions set forth herein, no assurances are provided by any
+   Contributor  that  the  Program  does not infringe the patent or other
+   intellectual property rights of any other entity. Each Contributor disclaims
+   any liability to Recipient for claims brought by any other entity based on
+   infringement of intellectual property rights or otherwise. As a condition to
+   exercising the rights and licenses granted hereunder, each Recipient hereby
+   assumes sole responsibility to secure any other intellectual property rights
+   needed, if any. For example, if a third party patent license is required to
+   allow Recipient to distribute the Program, it is Recipient's responsibility
+   to acquire that license before distributing the Program.
+
+   d) Each Contributor represents that to its knowledge it has sufficient
+   copyright rights in its Contribution, if any, to grant the copyright license
+   set forth in this Agreement.
+
+   3. REQUIREMENTS
+
+   A Contributor may choose to distribute the Program in object code form under
+   its own license agreement, provided that:
+
+   a) it complies with the terms and conditions of this Agreement; and
+
+   b) its license agreement:
+
+   i) effectively disclaims on behalf of all Contributors all warranties and
+   conditions, express and implied, including warranties or conditions of title
+   and   non-infringement,   and  implied  warranties  or  conditions  of
+   merchantability and fitness for a particular purpose;
+
+   ii) effectively excludes on behalf of all Contributors all liability for
+   damages, including direct, indirect, special, incidental and consequential
+   damages, such as lost profits;
+
+   iii) states that any provisions which differ from this Agreement are offered
+   by that Contributor alone and not by any other party; and
+
+   iv)  states  that  source  code for the Program is available from such
+   Contributor, and informs licensees how to obtain it in a reasonable manner
+   on or through a medium customarily used for software exchange.
+
+   When the Program is made available in source code form:
+
+   a) it must be made available under this Agreement; and
+
+   b) a copy of this Agreement must be included with each copy of the Program.
+
+   Contributors may not remove or alter any copyright notices contained within
+   the Program.
+
+   Each Contributor must identify itself as the originator of its Contribution,
+   if any, in a manner that reasonably allows subsequent Recipients to identify
+   the originator of the Contribution.
+
+   4. COMMERCIAL DISTRIBUTION
+
+   Commercial distributors of software may accept certain responsibilities with
+   respect to end users, business partners and the like. While this license is
+   intended to facilitate the commercial use of the Program, the Contributor
+   who includes the Program in a commercial product offering should do so in a
+   manner which does not create potential liability for other Contributors.
+   Therefore, if a Contributor includes the Program in a commercial product
+   offering, such Contributor ("Commercial Contributor") hereby agrees to
+   defend and indemnify every other Contributor ("Indemnified Contributor")
+   against any losses, damages and costs (collectively "Losses") arising from
+   claims, lawsuits and other legal actions brought by a third party against
+   the Indemnified Contributor to the extent caused by the acts or omissions of
+   such Commercial Contributor in connection with its distribution of the
+   Program in a commercial product offering. The obligations in this section do
+   not  apply  to  any claims or Losses relating to any actual or alleged
+   intellectual property infringement. In order to qualify, an Indemnified
+   Contributor must: a) promptly notify the Commercial Contributor in writing
+   of such claim, and b) allow the Commercial Contributor to control, and
+   cooperate with the Commercial Contributor in, the defense and any related
+   settlement negotiations. The Indemnified Contributor may participate in any
+   such claim at its own expense.
+
+   For example, a Contributor might include the Program in a commercial product
+   offering, Product X. That Contributor is then a Commercial Contributor. If
+   that  Commercial  Contributor then makes performance claims, or offers
+   warranties related to Product X, those performance claims and warranties are
+   such Commercial Contributor's responsibility alone. Under this section, the
+   Commercial  Contributor  would have to defend claims against the other
+   Contributors related to those performance claims and warranties, and if a
+   court requires any other Contributor to pay any damages as a result, the
+   Commercial Contributor must pay those damages.
+
+   5. NO WARRANTY
+
+   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED ON
+   AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER
+   EXPRESS  OR  IMPLIED  INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR
+   CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A
+   PARTICULAR PURPOSE. Each Recipient is solely responsible for determining the
+   appropriateness of using and distributing the Program and assumes all risks
+   associated with its exercise of rights under this Agreement , including but
+   not  limited to the risks and costs of program errors, compliance with
+   applicable laws, damage to or loss of data, programs or equipment, and
+   unavailability or interruption of operations.
+
+   6. DISCLAIMER OF LIABILITY
+
+   EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY
+   CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL,
+   SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION
+   LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN
+   CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE)
+   ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE
+   EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY
+   OF SUCH DAMAGES.
+
+   7. GENERAL
+
+   If  any  provision of this Agreement is invalid or unenforceable under
+   applicable law, it shall not affect the validity or enforceability of the
+   remainder of the terms of this Agreement, and without further action by the
+   parties hereto, such provision shall be reformed to the minimum extent
+   necessary to make such provision valid and enforceable.
+
+   If Recipient institutes patent litigation against any entity (including a
+   cross-claim or counterclaim in a lawsuit) alleging that the Program itself
+   (excluding combinations of the Program with other software or hardware)
+   infringes such Recipient's patent(s), then such Recipient's rights granted
+   under Section 2(b) shall terminate as of the date such litigation is filed.
+
+   All Recipient's rights under this Agreement shall terminate if it fails to
+   comply with any of the material terms or conditions of this Agreement and
+   does not cure such failure in a reasonable period of time after becoming
+   aware of such noncompliance. If all Recipient's rights under this Agreement
+   terminate, Recipient agrees to cease use and distribution of the Program as
+   soon as reasonably practicable. However, Recipient's obligations under this
+   Agreement and any licenses granted by Recipient relating to the Program
+   shall continue and survive.
+
+   Everyone is permitted to copy and distribute copies of this Agreement, but
+   in order to avoid inconsistency the Agreement is copyrighted and may only be
+   modified in the following manner. The Agreement Steward reserves the right
+   to publish new versions (including revisions) of this Agreement from time to
+   time. No one other than the Agreement Steward has the right to modify this
+   Agreement. The Eclipse Foundation is the initial Agreement Steward. The
+   Eclipse Foundation may assign the responsibility to serve as the Agreement
+   Steward to a suitable separate entity. Each new version of the Agreement
+   will  be given a distinguishing version number. The Program (including
+   Contributions) may always be distributed subject to the version of the
+   Agreement under which it was received. In addition, after a new version of
+   the Agreement is published, Contributor may elect to distribute the Program
+   (including its Contributions) under the new version. Except as expressly
+   stated in Sections 2(a) and 2(b) above, Recipient receives no rights or
+   licenses  to  the  intellectual property of any Contributor under this
+   Agreement, whether expressly, by implication, estoppel or otherwise. All
+   rights  in  the Program not expressly granted under this Agreement are
+   reserved.
+
+   This Agreement is governed by the laws of the State of New York and the
+   intellectual property laws of the United States of America. No party to this
+   Agreement will bring a legal action under this Agreement more than one year
+   after the cause of action arose. Each party waives its rights to a jury
+   trial in any resulting litigation.

+The AT&T Software Technology ast-ksh package from AT&T Research
+contains ksh and support libraries. This is the minimal set of
+components needed to build ksh.  This package is a superset of the
+following package: ksh; you won't need this if you download ast-ksh.
+
+Source Package Installation Instructions:
+
+  (1) Do not install packages as root/super-user. Although some components may
+      have setuid executables, few must be owned by root. These are best
+      changed manually when the security implications are understood.
+  (2) Choose a package root directory and cd to it. This will be a local work
+      area for all packages.
+  (3) These instructions bypass the click to download package links on the
+      download site. If you already clicked, or if your system does not have
+      curl(1), hurl(1), lynx(1) or wget(1) then use the alternate instructions
+      for (3),(4),(5) in plan B below. Plan B installs the hurl(1)
+      script which works with ksh and modern bash. The top level URL is:
+		URL=http://www.research.att.com/sw/download
+  (4) If the bin/package script does not exist then run:
+		test -d bin || mkdir bin
+		url=$URL/package
+		(wget -O bin/package $url||curl -L $url||hurl $url) > bin/package
+		chmod +x bin/package
+  (5) Determine the list of package names you want from the download site, then
+      use the package(1) command to do the actual download:
+		bin/package authorize "NAME" password "PASSWORD" \
+			setup source $URL PACKAGE ...
+      (Refer to the AUTHORIZATION paragraph on the main download page for
+      NAME/PASSWORD details.)  This downloads the closure of the latest
+      source package(s); covered and up-to-date packages are not downloaded again unless
+      package force ... is specified. Package content is verified using md5sum.
+      If the package root will contain only one architecture then you can install in bin and
+      lib instead of arch/HOSTTYPE/bin and arch/HOSTTYPE/lib by running this
+      instead:
+		bin/package authorize "NAME" password "PASSWORD" \
+			flat setup source $URL PACKAGE ...
+      To update the same packages from the same URL run:
+		bin/package setup source
+  (6) Build and install; all generated files are placed under arch/HOSTTYPE
+      ($INSTALLROOT), where HOSTTYPE is the output of bin/package (with no
+      arguments.) name=value arguments are supported; CC and debug=1 (compile
+      with -g instead of -O) are likely candidates. The output is written to
+      the terminal and captured in $INSTALLROOT/lib/package/gen/make.out:
+		bin/package make
+  (7) List make results and interesting errors:
+		bin/package results
+      Run the regression tests:
+		bin/package test
+      List test results and errors:
+		bin/package results test
+  (8) The generated binaries are position independent, i.e., they do not
+      contain hard-coded paths. However, commands with related files, like
+      file(1) and nmake(1), require the path of the bin directory to be
+      exported in PATH.
+  (9) You can run the binaries directly from the package root, or you can
+      install them in a public root after you are satisfied with the make and
+      test actions (requires the AT&T nmake(1) command):
+		bin/package flat install DIRECTORY PACKAGE
+      This will install in DIRECTORY/bin and DIRECTORY/lib. If you want to
+      preserve the arch/HOSTTYPE hierarchy under DIRECTORY then omit the
+      flat argument. If you don't have nmake(1) then the following will do a
+      flat install:
+		cd $INSTALLROOT
+		cp -p -r bin lib include DIRECTORY
+  (10) To summarize, after the first time the download, build, and test cycle
+      for the latest source release is:
+		bin/package setup source
+		bin/package make
+		bin/package test
+
+Source Package Installation Instructions -- Plan B:
+
+  (3) Create the subdirectory lib/package/tgz and download all package archives
+      into that directory.
+  (4) If the bin/package script does not exist then manually read the INIT
+      source package:
+		gunzip < lib/package/tgz/INIT.YYYY-MM-DD.tgz | tar xvf -
+      Note that some browsers automatically unzip downloaded without warning.
+      If the gunzip fails try:
+		tar xvf - lib/package/tgz/INIT.YYYY-MM-DD.tgz
+      If your system does not have tar(1) or gunzip(1) then download the ratz
+      source package, compile it, and manually read the INIT
+      source package:
+		mkdir bin
+		cp lib/package/tgz/ratz.YYYY-MM-DD.c lib/package/tgz/ratz.c
+		cc -o bin/ratz lib/package/tgz/ratz.c
+		bin/ratz -lm < lib/package/tgz/INIT.YYYY-MM-DD.tgz
+  (5) Read all unread package archive(s):
+		bin/package read
+      Both source and binary packages will be read by this step.

+10-09-28 +A new compile option SHOPT_FIXEDARRAY has been added and is being
+	  evaluation.  It allows fixed sized indexed arrays be to defined
+	  using "typeset array[dim1][dim2]...[dimn]".  Fixed sized arrays

+	  could get truncated has been fixed.
+10-06-24  If after executing a script found in FPATH, if a function, builtin,
+	  or type name corresponding to that script is not defined, the shell
+	  now outputs an error message and returns value 126.
+10-06-23  Floating point functions that happened to return integer values
+	  were being treated as if the function returned integers so that
+	  integer division could be used instead of floating point division.
+10-06-22  Fixed a bug in earlier ksh93u in which an arithmetic assignment to a
+	  variable in the global scope would instead create a local variable if
+	  the variable had an attribute but did not have a value.
+10-06-18  Modified trap handling so that if the same signal is received when
+	  executing the handler, it is deferred until the handler completes.
+10-06-16  Fixed a bug in which ulimit -v was setting the the cpu limit

+	  space via .name.var and .name.fun.  Variables and functions that
+	  are not in the namespace are not modified when running command.
+10-06-07  Change most internal interfaces to take Sh_t* argument.
+10-06-03 +Types can be loaded on first reference by putting definitions in

+	  reference could cause the value to display incorrectly has been fixed.
+10-05-21  A bug in which using $var inside ((...)) did not work when var was
+	  a hex float variable.
+10-05-20 +The compile option SHOPT_EDPREDICT has been added.  When this option
+	  is on, as you type a line beginning with a # the following characters
+	  are treated as a shell pattern and cause matching lines from the
+	  history file to be displayed as a numbered list as you type.
+	  You can scroll up and down this list or you can use <ESC>nTAB
+	  to make this the current line (n defaults to 1 of omitted) or
+	  <ESC>n<cr> to execute.
+10-05-20  A bug which caused an exception when multiple levels of composite
+	  functions in arithemtic expressions has been fixed.

+	  scope were not found has been fixed.
+10-04-30  Do not use socketpair() on systems that implement ioctl(I_PEEK)
+	  on pipes.
+10-04-29 +When the current job pool is set, coprocess are run in a job pool.
+10-04-28  A type defined with a member foo that is an associative array without
+	  elements followed by an expansion ${bar.foo[a]} and an assignment
+	  bar.foo[a]=b, no longer indicates that ${#bar.foo[@]} has 0 members.

+	  the subshell completed has been fixed.
+10-04-23  For file completion in commmand line editing, file names starting
+	  with # are now escaped so that they are not treated as comments.
+10-04-23  A bug in which ${t.var:=value}, where t is an instance of a type
+	  variable, could assign value to the type variable rather than to
+	  the type instance has been fixed.
+10-04-23 +Added &| which can be used in place of | to have portions of a
+	  pipeline executed in the pool.
+10-04-22 +The .sh.pool variable was added for use with job pools.

+10-04-15  A bug which caused scripts containing user defined math functions to
+	  fail to compile with shcomp has been fixed.
+10-04-15 +Job pools have been added with the SHOPT_COSHELL compilation option.
+	  A job pool allows a collection of background jobs to run either locally 
+	  or remotely and to be managed as a unit.  The command '& name ...'
+	  creates or uses a named job pool for subsequent background jobs.
+	  kill, wait, and jobs allow the pool name as operands.
+10-04-14  A bug in which a coprocess connection could terminate prematurely
+	  when running a nested subshell has been fixed.
+10-04-12 +Enumeration constants can be used in arithmetic expressions with the

+	  'function .sh.math.name x y z{...}' , where name is the function name
+	  invoked within ((...)) and x y z are long double arguments passed
+	  as name references.  y and z are used for functions with two and
+	  three arguments respectively.  The value of the function is the value
+	  of the long double .sh.value variable when the function returns.
+10-03-24  A bug in which integer division was mistakenly used when the
+	  numerator was a binary operator with the first operand floating
+	  point and the second integer, e.g. (.1**3)/3, has been fixed.

+	  created in the same physical directory as file.
+10-03-23  A warning message was added to sh -n when $var was used inside

+	  fixed.
+10-03-19  Removed space between Stopped message and (SIGTTIN) and (SIGTTOUT).
+10-03-17  Modified profile shell execution so that when builtins that
+	  correspond to executable have extended attributes, they are
+	  executed by pfksh instead of being treated as built-ins.
+10-03-16  A bug in whence -a which produced duplicate lines of output has
+	  been fixed.
+10-03-16  A bug in the handling of process groups in monitor mode for
+	  command substitutions has been fixed.

+	  that contained here-documents did not process correctly has been
+	  fixed.

+	  after read times out when in a multibyte locale with no edit mode
+	  enabled has been fixed.

+	  preceded by a colon will be traced but not executed.
+06-08-16 +As a new feature, a leading ~(N) on a pattern has no effect 
+	  except when used for file expansion.  In this case if not
+	  matches are found, the pattern is replaced by nothing rather
+	  than itself.
+06-08-11  A bug in the expansion of ${.sh.match[i]:${#.shmatch[i]}} has
+	  been fixed.
+06-08-10 +The read builtin options -n and -N have been modified to treat

+	  rather than a -, the first line of the here-document determines
+	  how much whitespace is removed for each line.

+	  selected when either /bin or /usr/bin is scanned.
+06-06-04 +Added literal-next character processing for emacs/gmacs mode. 
+	  This change is not compatible with earlier versions of ksh93
+          and ksh88 when the stty lnext is control-v.  The sequence
+	  escape-control-v will display the shell version.
+06-05-31 +Modified emacs and vi mode so that entering a TAB after a partial
+	  TAB completion, generates a listing of possible completions.
+	  After the second TAB, a number followed by a TAB will perform
+	  the completion with the corresponding item.
+06-05-19 +Modified arithmetic so that conversions to strings default to
+	  the maximum number of precision digits.
+06-05-16  Bug fixes for multibyte locales. 
+06-05-10  The =~ operator was added to [[...]] and  [[ string ~= ERE ]]

+06-01-23  A bug in which print -u<n> could fail when file descriptor <n> was
+	  open for writing has been fixed.
+06-01-19  The ?: arithmetic operator fixed to work when the operation after
+	  the colon was an assignment.
+05-12-24  A bug which could lead to a core dump when elements of a compound
+	  variable were array elements, i.e. foo=(bar=(1 2)), has been fixed.
+05-12-13  An arithmetic bug in which x+=y+=z was not working has been fixed. 
+05-12-13  An arithmetic bug in which x||y was returning x when x was non-zero
+	  rather than 1 has been fixed.
+05-12-07 +The aliases for integer and float have been changed to use attributes
+	  -li and -lE to handle long long and long double types.
+05-12-07 +The histexpand (-H) option has been added which allows C-shell
+	  style history expansions using the history character !.
+05-12-07 +The multiline option was added which changes that way the edit
+	  modes handle lines longer than the window width.  Instead of
+	  horizontal scrolling, multiple lines on the screen are used.
+05-12-05  The whence builtin now returns an absolute pathname when the
+          command is found in the current directory.
+05-11-29  A bug which caused ksh -c '[[ ! ((' to core dump rather than
+	  report a syntax error has been fixed.
+05-11-29  A bug when reading fixed length records into typeset -b variables
+	  which caused a zero byte to terminate the value has been fixed.
+05-11-22 +The ability to seek to an offset within a file has been added
+	  with the new I/O redirection operators, <#  and >#.  Currently,
+	  these redirection operators must be followed by ((expr))
+	  but in a future release, it should be able to used to seek forward
+	  to the specified shell pattern.  In addition $(n<#) expands to the
+	  current byte offset for file descriptor n.
+05-11-22 +The .sh.match array variable is now set after each [[ ... ]]
+	  pattern match.  Previously it was only set for substring matches.
+05-10-17  A bug in which the library path variable could be prefixed
+          with a directory when a .path file was not encountered in
+	  the directory of the executable has been fixed.
+05-09-15  A for/while loop optimizer bug in which $OPTIND was not
+	  correctly expanded has been fixed.
+05-09-05  A bug in which a history command that invoked a history
+	  command could go into an infinite loop has been fixed.
+05-08-31 +In the case that IFS contains to adjacent new-lines so that
+	  new-line is not treated as a space delimiter, only a single
+	  new-line is deleted at the end of a command substitution.
+05-08-19 +When a tilde substitution expands to the / directory and is
+	  followed by a /, it is replaced by the empty string.
+05-08-16  A bug in which n<&m did not synchronize m has been fixed.
+05-08-16  A bug in which process substitution  ( <() and >() ) was not
+	  working within for and while loops has been fixed.
+05-07-24  A bug in which the pattern ~(E)(foo|bar) was treated as a syntax
+	  error has been fixed.
+05-07-24  A bug in completion with <n>=, where n was the one of the
+	  previous selection choices has been fixed.
+05-07-21  A bug with multibyte input when no edit mode was specified which
+	  caused the input line to shift left/right has been fixed.
+05-06-24  A race condition which could cause the exit status to get lost
+	  on some fast systems has been fixed.
+05-06-21  A bug in which nested patterns of the form {m,n}(pat) would cause
+	  syntax errors has been fixed.
+05-06-21  A bug in the macro expander has been fixed which could cause a
+          syntax error for an expansion of the form ${x-$(...)} when
+	  x is set and the command substitution contained certain strings.
+05-06-08 +On systems for which echo does not do System V style \ expansions,
+	  the -e option was added to enable these expansion.
+05-06-08  A bug in which ${var op pattern} to not work when inside an
+	  arithmetic expression has been fixed.
+05-05-23 +An extension to shell patterns that allows matching of nested
+	  groups while skipping over quoted strings has been added.
+05-05-18  A bug in which the line number for errors was not correct for
+          functions loaded from FPATH has been fixed.
+05-04-18  A bug in which the exit status $? is not set when a trap triggered
+	  by the [[...]] command is executed has been fixed.
+05-04-08 +Redirection operators can be directly preceded with {varname}
+	  with no intervening space, where varname is a variable name which
+	  allows the shell to select a file descriptor > 10 and store it
+	  into varname.
+05-04-08 +SHOPT_CMDLIB_BLTIN=1 now includes <cmdlist.h> generated table.
+05-04-07 +[[ -o ?option ]] is true if "option" is a supported option.
+05-04-05  A bug in handling file completion with spaces in the names
+          has been fixed.
+05-03-25 +The SIGWINCH signal is caught by default to keeps the LINES and
+	  COLUMNS variables in sync with the actual window size.
+05-03-25 +Building ksh with SHOPT_REMOTE=1 causes ksh to set --rc if stdin is
+	  a socket (presumably part of a remote shell invocation.)
+05-03-25 +Building ksh with SHOPT_SYSRC=1 causes interactive ksh to source
+	  /etc/ksh.kshrc (if it exists) before sourcing the $ENV file.
+05-03-25 +{first..last[..incr][%fmt]} sequences added to brace expansions
+	  when braceexpand is enabled.
+05-03-03  A bug where a SIGCHLD interrupt could cause a fifo open to fail has
+	  been fixed.
+05-02-25  A bug in which a builtin command run in the background could
+	  keep a file descriptor open which could cause a foreground
+	  process to hang has been fixed.
+05-02-24  A bug where builtin library commands (e.g., date and TZ) failed to
+	  detect environment variable changes has been fixed.
+05-02-22 +The read builtin and word splitting are now consistent with respect
+	  to IFS -- both treat IFS as field delimiters.
+05-02-22 +The read builtin no longer strips off trailing delimiters that
+	  are not space characters when there are fewer variables than fields.
+05-02-17  A builtin bug on systems where dlsym(libcmd) returns link-time
+	  bindings has been fixed.
+05-02-12  A bug in which the lib_init() function for .paths BUILTIN_LIB
+	  libraries was not called has been fixed.
+05-02-06  A bug on some systems in which moving the write end of a co-process
+	  to a numbered file descriptor could cause it to close has been fixed. 
+05-02-06  A bug in the vi-edit mode in which the character under the cursor
+	  was not deleted in some cases with the d% directive has been fixed.

+          stdout has been fixed.
+05-02-04  A bug where times formatting assumed CLK_TCK==60 has been fixed.
+
+05-01-11  --- Release ksh93q  ---
+05-01-11  A bug in the integral divide by zero check has been fixed.
+05-01-11 +The -l option has been added to read /etc/profile and
+	  $HOME/.profile, if they exist, before the first command.
+05-01-11  An argument parsing bug that caused `kill -s x -- n' to fail has
+	  been fixed.
+05-01-11 +The .paths file, introduced in ksh93m, which can appear in
+	  any directory in PATH, now allows a line of the form 'BUILTIN_LIB=.'
+	  When a command is searched for this directory, and the full path
+	  matches the path of the built-in version of the command (listed
+	  by the 'builtin' command) then the built-in version of the command
+	  is used.  When ksh is built with SHOPT_CMDLIB_DIR=1 then all libcmd
+	  functions become builtins with the '/opt/ast/bin/' directory prefix.
+05-01-10  A bug in which a nameref to a compound name caused a core dump has
+	  been fixed.
+05-01-09  A bug in which some SIGCHLD interrupts (from child processes exiting)
+	  caused a fatal print/echo error diagnostic has been fixed.
+04-12-24  A bug in which some SIGCHLD interrupts (from child processes exiting)
+          corrupted the internal process/job list, sometimes causing the shell
+	  to hang, has been fixed.
+04-12-01  A bug in which typeset -Fn truncated less than n digits for large
+	  numbers has been fixed.
+04-11-25  A bug in which standard error could be closed after a redirection
+	  to /dev/stderr has been fixed.
+04-11-17  A bug in which an expansion of the form ${array[@]:3} could expand
+          to ${array[0]} when ${array[3]} was not set has been fixed.
+04-10-22 +The -E or -orc command line option reads ${ENV-$HOME/.kshrc} file.
+04-10-22 +`-o foo' equivalent to `+o nofoo', `-o nobar' equivalent to `+o bar'.
+          `--foo' equivalent to `-o foo', `--nofoo' equivalent to `+o foo'
+04-10-05 +The .paths file, introduced in ksh93m, which can appear in
+	  any directory in PATH, now allows a line of the form
+	  'BUILTIN_LIB=libname'.  When a command is searched for this directory,
+	  the shared library named by libname will first be searched for a
+	  built-in version of the command.
+04-09-03  <<< here documents now handle quotes in the word token correctly. 
+04-08-08 +The maximum size for read -n and and read -N was increased from
+	  4095 to 32M.
+04-08-04 +printf %q was modified so that if an no operand was supplied, no
+	  no output would be generated rather than a quoted empty string.
+04-08-01 +The -n and -N options of the read builtin has been modified
+	  when reading variables with the binary attribute so that the
+	  data is stored directly rather than through assignment.
+04-08-01 +The shcomp command has been modified to process alias commands
+	  under some conditions.
+04-07-31 +The .sh.match variable added in ksh93l, now works like other
+	  indexed arrays.
+04-07-08  A loop optimizer bug which occurs when typeset is used in
+	  a for or while loop inside a function has been fixed.
+04-06-24 +The number of subexpressions in a pattern was increased to 64
+	  from the current number of 20.
+04-06-17 +The -t option to read was modified to allow seconds to be
+	  specified as any arithmetic expression rather than just
+	  an integral number of seconds, for example even -t 'sin(.5)'
+	  is now valid.
+04-06-16  Two small memory leak problems were fixed.
+04-06-15  A bug in ${var/pattern/"string"} which occurred when string
+	  contained pattern matching characters has been fixed.
+04-05-08  printf $'%d\n' produced an erroneous error message and has
+	  been fixed.
+04-05-24  A bug in which an associative array without any elements could
+	  cause a core dump when a script with an associative array with
+	  the same name was declared in a script invoked by name has
+	  been fixed.
+04-05-11  A bug in which an exec statement could close the script that
+	  is being processed in a script that is run by name causing
+	  a failure has been fixed.
+04-04-28 +If the first character of assignment to an integer variable was 0,
+          the variable had been treated as unsigned.  This behavior was
+          undocumented and has been removed.
+04-04-05  A bug in which the positioning of standard input could be incorrect
+	  after reading from standard input from a subshell has been fixed.
+04-03-30  A bug in the for loop optimizer which in rare cases could cause
+	  memory corruption has been fixed.
+04-03-29 +The preset alias source='command .' has been added.
+04-03-29  A bug introduced in ksh93p on some systems in which invoked by
+	  name with #! on the first line would not get the signals handling
+	  initialized correctly has been fixed. 
+04-03-29  A bug introduced in ksh93p in which a HUP signal received by
+	  a shell that is a session group leader was not passed down to
+	  its children has been fixed.
+
+04-02-28  --- Release ksh93p  ---
+04-02-28 +The ability to apply an append discipline to any variable has
+	  been added.
+04-02-14  A bug in which the exportall option (set -a) would cause incorrect
+	  results for arrays has been fixed.
+04-02-02  A bug in which an exported array would pass more than
+	  the first element to a script invoked by name has been fixed.
+04-02-02  A bug on some systems in which name=value pairs preceding a script
+	  invoked by name was not getting passed to the script has been fixed.
+04-01-20  A bug in which an unset discipline function could cause a core
+	  dump on some systems has been fixed.
+04-01-12  A bug in which a continue or break called outside a loop from
+	  inside a function defined with name() syntax could affect 
+	  the invoking function has been fixed.
+04-01-08  If a command name begins with ~, only filename completion will be
+	  attempted rather than pathname completion using the builtin editors. 
+04-01-08  A bug in the vi edit mode in which the wrong repeat count on
+	  multiple word replacements with the . directive has been fixed.
+04-01-06  Backspace characters are now handled correctly in prompt strings.
+04-01-06 +The getopts builtin has been modified to accept numerical
+	  arguments of size long long on systems that support this.
+04-01-06  A bug in which unsetting all elements of an associative array
+	  would cause it to be treated as an indexed array has been fixed.
+03-12-15  A bug in which a quoted string ending with an unescaped $ would
+	  delete the ending $ in certain cases has been fixed.
+03-12-05  A bug in which the shell could hang when set -x tracing a command
+	  when an invalid multibyte character is encountered has been fixed. 
+03-12-05  On some systems, if the KEYBD trap is set, then commands that use
+	  the meta key were not processed until return was hit.  This
+	  has been fixed.
+03-12-05  A problem which occurred when the login shell was not a group
+	  leader that could cause it to fail has been fixed.
+03-12-05  A problem in which a shell could core dump after receiving a signal
+	  that should cause it to terminate while it was in the process
+	  of acquiring more space has been fixed.
+03-12-05 +If ENV is not specified, the shell will default to $HOME/.kshrc
+	  for interactive shells.
+03-11-21  A bug introduced in ksh93o in which the DEBUG trap could get
+	  disabled after it triggered has been fixed. 
+03-11-04  A bug in which using arithmetic prefix operators ++ or -- on a
+	  non-lvalue could cause a core dump has been fixed.
+03-11-04  A bug in which leading zeros were stripped from variable
+	  expansions within arithmetic computation to avoid being treated
+	  as octal constants when they should not have, has been fixed.
+03-10-08  A bug introduced in ksh93o in which a large here document inside
+	  a function definition could get corrupted has been fixed.
+03-09-22  A bug in which the .get discipline function was not being
+	  called when a string variable was implicitly referenced from
+	  within a numerical expression has been fixed.
+03-09-22  A bug in which a script without a leading #! could get executed
+	  by /bin/sh rather than the current shell on some systems has
+	  been fixed.
+03-09-12 +To improve conformance with ksh88, leading zeros will be ignored
+	  when getting the numerical value of a string variable so that
+	  they will not be treated as octal constants.
+03-09-03 +The builtin kill command now processes obsolete invocations
+	  such as kill -1 -pid.
+03-09-02  The restriction on modifying FPATH in a restricted shell (sh -r)
+	  has been documented.
+03-09-02 +The restricted shell (sh -r) has been modified to disallow
+	  executing command -p.
+03-08-07  A bug in which the KEYBD trap was not being invoked when
+	  characters with the 8th bit set has been fixed.
+03-08-02  A parser bug introduced in ksh93o which caused the character
+	  after () in a Posix function definition to be skipped 
+	  when reading from standard input has been fixed.
+03-08-01  A bug in which "${foo#pattern}(x)" treated (x) as if it were
+	  part of the pattern has been fixed.
+03-08-01 +The command -x option has been modified so that any trailing
+	  arguments that do expand to a single word will be included
+	  on each invocation, so that commands like command -x mv * dir
+	  work as expected.
+
+03-07-20  --- Release ksh93o+  ---
+03-07-20  A bug in which could cause memory corruption when a posix
+	  function invoked another one has been fixed.
+03-07-15  A bug in which a file descriptor>2 could be closed before
+	  executing a script has been fixed.
+03-07-15  A parsing error for <() and >() process substitutions inside
+	  command substitution has been fixed.
+03-07-15  A parsing error for patterns of the form {...}(...) when
+	  used inside ${...} has been fixed.
+03-07-15  An error in which expanding an indexed array inside a compound
+	  variable could cause a core dump has been fixed.
+03-07-15  A bug in which on rare occasions a job completion interrupt
+	  could cause to core dump has been fixed.
+03-06-26  A bug in which process substitution embedded within command
+	  substitution would generate a syntax error has been fixed.
+03-96-23  A bug in which ${@:offset:len} could core dump when there
+	  were no arguments has been fixed.
+03-96-23  A bug in which ${X[@]:offset:len} could core dump when X
+	  was unset has been fixed.
+03-06-22 +The -x option was added to the command builtin.  If this
+	  option is on, and the number of arguments would exceed ARG_MAX,
+	  the command will be invoked multiple times with a subset of
+	  the arguments.  For example, with alias grep='command -x grep,
+	  any number of arguments can be specified.
+03-06-14  A bug in which could cause a core dump on some systems with
+	  vi and emacs editors with the MULTIBYTE option has been fixed.
+03-06-06  A bug in which the shell could core dump when a script was
+	  run from its directory, and the script name a symlink to a file
+	  beginning with .., has been fixed.
+03-06-05  A bug in which the shell could core dump when a child process
+	  that it is unaware of terminates while it is calling malloc()
+	  has been fixed.
+03-06-02 +An option named globstar (set -G) has been added.  When enabled,
+	  during pathname expansion, any component that consists only of ** is
+	  matches all files and any number of directory levels.
+03-05-30  A bug in which the PATH search could give incorrect results when
+	  run from directory foo and PATH contained .:foo:xxx has been fixed.
+03-05-29 +Some changes were made to the code that displays the prompt in edit 
+	  mode to better handle escape sequences in the prompt.
+03-05-27  I added = to the list of characters that mark the beginning of
+	  a word for edit completion so that filenames in assignments
+	  can be completed.
+03-05-20  A bug in which read -N could hang on some systems when reading
+	  from a terminal or a pipe has been fixed.
+03-05-19  A bug in which the output of uname from a command substitution
+	  would go to the standard output of the invoking command when
+	  uname was invoked with a non-standard option has been fixed.
+03-05-19  A job control bug which would cause the shell to exit because 
+	  it hadn't take back the terminal has been fixed.  The bug
+	  could occur when running a function that contained a pipeline
+	  whose last element was a function.
+03-05-19  A job control timing bug introduced in ksh93o on some systems
+	  which could cause a pipeline to hang if the first component
+	  completed quickly has been fixed.
+03-05-13 +The read builtin has been modified so that the builtin editors
+	  will not overwrite output from a previous incomplete line. 
+03-05-13  A bug in which the name of an identifier could have the string
+	  .sh. prefixed to it after expanding a variable whose name begins
+	  with .sh. has been fixed.
+03-05-13  A bug in the expansion of $var for compound variables in which
+	  some elements would not be output when the name was a prefix
+	  of another name in the compound variable has been fixed.
+03-05-08  The last item in the ksh93o release on 03-01-02 has been
+	  altered slightly to preserve the leading 0's when the
+	  preceding character is a digit.  Thus, with typeset -LZ3 x=10,
+	  $(( 1$x)) will be 1010 whereas $(( $x) will be 10.
+03-04-25  A bug in which if x is a name reference, then nameref y=x.foo
+	  did not follow x has been fixed.
+
+03-03-18  --- Release ksh93o  ---
+03-03-18 +A -N unary operator was added to test and [[...]] which returns
+	  true if the file exists and the file has been modified since it
+	  was last read.
+03-03-18 +The TIMEFORMAT variable was added to control the format for
+	  the time compound command.  The formatting description is
+	  described in the man page.
+03-03-06 +A -N n option was added to read which causes exactly n bytes
+	  to be read unlike -n n which causes at most n bytes to be read.
+03-03-03 +Three new shell variables were added.  The variable .sh.file
+	  stores the full pathname of the file that the current command
+	  was found in.  The variable .sh.fun names the current function
+	  that is running.  The variable .sh.subshell contains the depth
+	  of the current subshell or command substitution.
+03-03-03 +When the DEBUG trap is executed, the current command line after
+	  expansions is placed in the variable .sh.command.  The trap
+	  is also now triggered before each iteration of a for, select,
+	  and case command and before each assignment and redirection.
+03-02-28 +Function definitions are no longer stored in the history file so
+	  that set -o nolog no longer has any meaning.
+03-02-28 +All function definitions can be displayed with typeset -f not
+	  just those stored in the history file.  In addition, typeset +f
+	  displays the function name followed by a comment containing the
+	  line number and the path name for the file that defined this function.
+03-02-28  A bug in which the value of $LINENO was not correct when executing
+	  command contained inside mult-line command substitutions has been
+	  fixed.
+03-02-19 +Since some existing ksh88 scripts use the undocumented and
+	  unintended ability to insert a : in front of the % and # parameter
+	  expansion operators, ksh93 was modified to accept :% as equivalent
+	  to % and :# as equivalent to # with ${name op word}.
+03-02-14  A bug which could cause a core dump when reading from standard
+	  error when standard error was a pty has been fixed.
+03-02-14 +The shell arithmetic was modified to use long double on systems
+	  that provide this data type.
+03-02-09  A bug in which a function located in the first directory in FPATH
+	  would not be found when the last component of PATH was . and the
+	  current directory was one of the directories in PATH has been fixed.
+03-02-07 +The trap and kill builtin commands now accept a leading SIG prefix
+	  on the signal names as documented.
+03-02-05  A bug in the expansion of ${var/$pattern}, when pattern contained
+	  \[ has been fixed.
+03-02-05  A bug in which .sh.match[n], n>0, was not being set for substring
+	  matches with % and %% has been fixed.
+03-01-15  A bug in which getopts did not work for numerical arguments specified
+	  as n#var in the getopts string has been fixed.
+03-01-09  A bug in which using ${.sh.match} multiple times could lead to
+	  a memory exception has been fixed.
+03-01-06  A bug in the expansion of ${var/pattern/$string} in the case that
+	  $string contains \digit has been fixed. 
+03-01-02 +A -P option was added for systems such as Solaris 8 that support
+	  profile shell.
+03-01-02  For backward compatibility with ksh88, arithmetic expansion
+	  with ((...)) and let has been modified so that if x is a zero-filled
+	  variable, $x will not be treated as an octal constant.
+
+02-12-05  --- Release ksh93n+  ---
+02-11-30  A bug that can show up in evaluating arithmetic statements that
+	  are in an autoloaded function when the function is autoload from
+	  another function has been fixed.
+02-11-30  An optimization bug in which an expansion of the form ${!name.@},
+	  which occurred inside a for or a while loop, when name is a name
+	  reference, has been fixed.
+02-11-18  A bug in which modifying array variables in a subshell could leave
+	  side effects in the parent shell environment has been fixed.
+02-11-18  A memory leak when unsetting an associative array has been fixed.
+02-11-14 +The code to display compound objects was rewritten to make
+	  it easier for runtime extensions to reuse this code.
+02-11-14 +A change was made to allow runtime builtins to be notified when
+	  a signal is received so that cleanup can be performed.
+02-10-31 +User applications can now trap the ALRM signal.  Previously,
+	  the ALRM signal was used internally and could not be used
+	  by applications. 
+02-10-31  A bug in which signals received while reading from a coprocess
+	  for which traps were set was not handled correctly has been fixed.
+02-10-31  A bug in which a file opened with exec inside a subshell could

+02-10-21  A bug in which setting PATH or FPATH inside a function might not
+	  take effect has been fixed.
+02-10-21  A bug which could cause a core dump when a local SECONDS variable
+	  is defined in a function has been fixed.
+02-10-15  A bug in which the associate array name operator ${!array[@]}
+	  could return the same name multiple times has been fixed.
+02-10-15  A bug in which the zero'th element of an associative array was
+	  not getting set when an assignment was made without a subscript
+	  specified has been fixed.
+
+02-09-30  --- Release ksh93n  ---
+02-09-30 +The maximum indexed array size was increased to 16Megs.
+02-09-30  A bug which could cause a core dump when changing attributes
+	  of associative array has been fixed.
+02-09-30  A bug in which exporting an array variable would not export the
+	  0-th element has been fixed.
+02-09-30  A bug in which an array assignment of the form a=($a ...) would unset
+	  'a' before the right hand side was evaluated has been fixed.
+02-09-27  A bug in which the error message for ${var?message} when var was
+	  null or unset did not contain the variable name var has been fixed.
+02-09-27  A bug in which closing file descriptors 0 through 2 could
+	  cause a subsequent here document to fail has been fixed. 
+02-09-14  A bug in whence which occurs when the specified name contained
+	  a / has been fixed.
+02-09-14  A bug in the parser for strings of the form name$((expr))=value
+	  has been fixed.
+02-09-14  A for loop optimization bug in which the number of elements in
+	  an array was treated as an invariant has been fixed.
+02-09-09  A bug in which redirection or closing of a file descriptor between
+	  3 and 9 could cause a subsequent here document to fail has been
+	  fixed. 
+02-09-09  A bug in which a background job was not removed from the job list
+	  when a subshell completed has been fixed, for example (prog&). 
+02-09-03  A bug in which an assignment of the form name=(integer x=3)
+	  could be interpreted as an array assignment rather than a
+	  compound variable assignment has been fixed.
+02-08-19  A command completion bug which occurred on file systems that
+	  are case insensitive has been fixed.
+02-08-19  A bug which could lead to an exception on some systems (for
+	  example FREEBSD) which occurred when setting PATH has been fixed.
+02-08-11  A bug in arithmetic rounding in which a value input as a decimal
+	  string would output as a rounded version of the string has
+	  been fixed.
+02-08-11  A bug in which the last character could be deleted from shell
+	  traces and from whence when called from a multibyte locale
+	  has been fixed.
+02-08-01  A bug which could cause a core dump to occur when a shell script
+	  is executed while a coprocess is running that has closed the
+	  output pipe has been fixed.
+02-08-01  A bug in which command completion in multibyte mode could
+	  corrupt memory for long command lines has been fixed.
+
+02-06-17  --- Release ksh93n-  ---
+02-06-17  A bug in which user defined macros could cause a core dump in
+	  with MULTIBYTE mode has been fixed.
+02-06-17  A bug in which printf format specifiers of the form %2$s were causing
+	  a core dump has been fixed.
+02-06-17  A bug in which setting stty to noecho mode did not prevent the
+	  echoing of characters by ksh when emacs or viraw mode
+	  was enabled has been fixed.
+02-06-17  A bug in which background job completion could cause the sleep
+	  builtin to terminate prematurely has been fixed.
+02-06-17  A bug in which the shell could core dump if getopts was called
+	  when the OPTIND variable contained a negative value has been fixed. 
+02-06-10 +The edit mode prompt has been modified to handle escape sequences.  
+02-06-10  A bug which occurred for interactive shells in which the builtin
+	  cat command was used in command substitution on a file whose
+	  size was larger than PIPE_BUF has been fixed.
+02-06-10  A bug in which the trap on ERR was not being processed when
+	  set inside a function has been fixed.
+02-06-07  A bug in which function definitions could cause the history count
+	  to be decremented by one (and even become negative) has been fixed.
+02-06-05  A bug in read in which share mode could be enabled has been fixed.
+02-05-28  A bug which could occur when the last command of a script was
+	  a case statement and the action selected ended in ;& instead of ;;
+	  has been fixed.
+02-05-23  A bug with unary + introduced in ksh93k has been fixed.
+02-05-07  A bug in substitutions of the form ${var/pattern/string} in which
+	  a backslash was inserted in the replacement string when it contained
+	  a special pattern character has been fixed.
+02-05-01  A bug in the emacs edit mode which occurred in versions compiled
+	  for multibyte character sets which occurred when a repeated search
+	  was requested after a long line had been returned for the previous
+	  search has been fixed.
+02-04-02 +vi and emacs edit modes were modified so that tab completion is
+	  disabled when invoked from the read built-in.
+
+02-03-26  --- Release ksh93m+  ---
+02-03-26  A bug in which \ was not handled correctly when used in file
+	  expansion has been fixed.
+02-02-18  A bug in which lines beginning with a # were deleted from here
+	  documents when the here-document delimiter was followed by
+	  a comment has been fixed.
+02-12-06  An optimization bug in which ${!x[@]) was treated as invariant in
+	  a for loop has been fixed.
+02-02-06  A bug in which the ERR trap is not cleared for a script invoked
+	  by name from within a function has been fixed.
+02-01-08  A bug in which a shell script executed from within a subshell
+	  could cause this script to have an invalid pointer leading
+	  to a memory fault has been fixed. 
+02-01-07 +Added here documents of the form <<< word (as per zsh) which
+	  is equivalent to << delim\nword\ndelim.
+02-01-07  A bug in which the first word of a compound assignment,
+	  x=(word ...), was treated as a reserved word has been fixed.
+02-01-07  A bug in the handling of \ when noglob was enabled and a
+	  substitution of the form ${word op pattern} occurred in the
+	  same word has been fixed.
+02-01-07 +A compilation option, CMDLIB_BLTIN in the file OPTION, has
+	  been added.  When this options is set, all commands implemented
+	  in libcmd become shell builtin commands by default.
+02-01-07  A bug in which builtin foo, where foo is already a builtin
+	  would result in the builtin foo getting removed has been fixed. 
+02-01-07  A bug which the shell executed a command found in the current
+	  directory when PATH have no valid directories has been fixed.
+01-11-28  The value of $? was not being set when called with exit.
+01-11-28  If the last command was of the form (...) and a trap on EXIT or
+	  ERR was set, and the command inside () modified the trap, then
+	  the original trap wasn't executed.
+01-11-26 +The value for 0 is now preceded by the base number when
+	  the base was not 10.
+01-11-26 +The default has compilation mode has been changes so that

+
+01-10-31  --- Release ksh93m  ---
+01-10-31  A for loop optimizer bug for subshells contained withing for
+	  loops has been fixed.
+01-10-16  typeset without arguments no longer outputs variable names

+01-10-16  A bug introduced in ksh93l in which assignments specified with
+	  the exec built-in were not being expanded properly has been
+	  fixed.
+01-10-11  An optimization bug in which ${!x) was treated as invariant in
+	  a for loop has been fixed.
+01-10-11  Unsigned integer variables in bases other than 10 are printed now
+	  expand in that base with the base prefix.
+01-10-10  A number of typos in the self generating man pages for shell
+	  built-ins have been fixed.
+01-10-04  The self generated man pages for hist and fc were not working
+	  correctly and have been fixed.

+	  treated as invariants has been fixed.
+01-09-27  Two bugs relating to multibyte history searches and to find
+	  have been fixed.
+01-09-27  A bug introduced in ksh93k in which the PATH searching was
+	  not restored after running a command with an assignment list 
+	  has been fixed.
+01-09-26  A bug in which a zero filled field was treated as octal when
+	  converted to integer has been fixed.
+01-09-26  Yet another bug in the optimization of for loops related to
+	  recursive functions with break or continue statements has been fixed.
+01-09-25 +The exponentiation operator ** was added to the shell arithmetic
+	  evaluation.  It has higher precedence than * and is left
+	  associative.
+01-09-25  The code was modified to use the ast multibyte macros
+	  and functions for handing multibyte locales.
+01-09-25 +The expansion ${parameter:offset:length} now handles negative
+	  offsets which cause offsets to be measured from the end.
+01-09-25  Some spelling errors in the documentation were corrected.
+01-09-24 +The /dev/tcp/host/port and /dev/udp/host/port now allow
+	  the ports to be specified by service name. 
+01-09-24 +The change staring with ksh93g in which the the appropriate
+	  library path variable is prepended with a corresponding library
+	  directory has been modified.  With the new method, only the
+	  library path defined in the file named .paths in the directory
+	  where the executable is found will be modified.  See the
+	  man page for more details.
+01-09-23 +The .fpath file (see ksh93h) is no longer looked for in each
+	  directory on the path to locate function directories.  The
+	  file named .paths is used instead.
+01-09-23  A bug in which IFS was not being restored after being changed in
+	  a subshell has been fixed.
+01-09-16 +With the vi and emacs edit modes, after a list of command
+	  or functions is generated with = or M-= respectively,
+	  any element from the list can be pasted on the command line
+	  by preceding the = or M-= with a numeric parameter specifying
+	  the position on the list.
+01-09-16  A bug in ksh93l caused command completion not to find aliases
+	  and functions.  Command listing from the edit mode was presented
+	  in reverse order.  This has been fixed.
+01-09-13  Another bug in the optimization of for loops related to subshells
+	  when traps were set has been fixed.
+01-09-07  A change in ksh93l caused brace expansion to stop working
+	  and this has been fixed.
+01-09-04  A bug introduced in ksh93k in which an arithmetic statement
+	  within a function that used name references did not follow the
+	  reference has been fixed.
+01-09-04  A bug introduced in ksh93l in which export -p did not prefix
+	  each export with the word export has been fixed.
+01-08-29  A bug in multibyte input which occurred when a partial multibyte
+	  character was received has been fixed.
+01-08-29  A bug introduced in ksh93l which could cause a core dump
+	  when an assignment list containing PATH is specified inside
+	  command substitution has been fixed.
+01-08-09  Another bug in the optimization of for loops in ksh93l caused
+	  errors in recursive functions using local variables that
+	  contained for loops has been fixed.
+01-07-27  A bug in which IFS would be unset after a command substitution
+	  inside a here document has been fixed.
+01-07-26  To conform to the POSIX standard, if you invoked ksh name,
+	  and name does not contain a /,  it will first try to run
+	  one in the current directory whether it is executable or not
+	  before doing a path search for an executable script.  Earlier
+	  versions first checked for an executable script using the
+	  PATH variable.
+01-07-23  A bug in which unset -f invoked in a subshell could unset a
+	  function defined in the parent has been fixed.
+01-07-16  A bug in the optimization of for loops in ksh93l caused
+	  name references to be treated as invariants has been fixed.
+01-07-09  A bug in which a discipline function applied to a local variable
+	  could cause a shell exception has been fixed.  Discipline
+	  functions can only be specified for global variables. 
+
+01-06-18  --- Release ksh93l  ---
+01-06-18  A bug in assigning integers larger than can be represented as
+	  long integers to floating point variables has been fixed.
+01-06-18  A bug in the handling of unsigned integers (typeset -ui) has
+	  been fixed.
+01-06-04  The evaluation of the PS1 prompt no longer effects the value
+	  of the $? variable.
+01-06-01  A small memory leak from subshells has been fixed.
+01-05-22  A bug in which attributes for variables that did not have
+	  values would be lost after a subshell has been fixed.
+01-05-22 +The %R format has been added to convert a shell pattern into
+	  an extended regular expression.
+01-05-22 +The escape sequences \e, \cX, \C[.collating-element.], and
+	  \x{hex} have been added to ASCII-C strings and to printf format
+	  strings.
+01-05-20 +Patterns of the form {n}(pattern) and {m,n}(pattern) are now
+	  recognized.  The first form matches exactly n of pattern whereas,
+	  the second form matches from m to n instances of pattern.
+01-05-20 +The shell allows *-(pattern), +-(pattern),  ?-(pattern),
+	  {m,n}-(pattern}, and @-(pattern) to cause the minimal
+	  match of pattern to be selected whenever possible rather
+	  than the maximal (greedy) match. 
+01-05-20 +The character class [:word:] has been added to patterns.
+	  The word class is the union of [:alnum:] and the character _.
+01-05-20 +Inside (...) pattern groups, the \ character is now treated
+	  specially even when in an enclosing character class.  The
+	  sequences, \w, \d, \s are equivalent to the character classes
+	  word, digit, and space respectively.  The sequences \W, \D,
+	  and \S are their complement sets. 
+01-05-20 +The shell now recognizes pattern groups of the form
+	  ~(options:pattern) where options or :pattern can be omitted.
+	  Options use the letters + and - to enable and disable options
+	  respectively.  The option letters g (greedy), i (ignore case)
+	  are used to cause maximal matching and to cause case
+	  insensitive matching respectively.  If :pattern is also
+	  specified, these options are only in effect while this
+	  pattern is being processed.  Otherwise, these options remain
+	  in effect until the end of the pattern group that they are contained
+	  in or until another ~(...) is encountered.  These pattern groups
+	  are not counted with respect to group numbering.
+01-05-14  When edit completion, expansion, or listing occurs in the
+	  middle of a quoted string, the leading quote is ignored when
+	  performing the completion, expansion, or listing.
+01-05-14  A small memory leak from subshells has been fixed.
+01-05-10  A bug in which open files were not restored after a subshell
+	  that had used exec to replace a file has been fixed. 
+01-05-10 +Redirection to a null file name now generates an error message. 
+01-05-09  The shell now rejects some invalid parameter substitutions that
+	  were previously processed in undefined ways.
+01-05-09  A bug in which the output of select was not flushed before the
+	  read when input did not come from the terminal has been fixed. 
+01-05-08  A bug in which job ids would not be freed for interactive shells
+	  when subshells ran built-ins in the background has been fixed.
+01-05-08 +The FPATH variable now requires an explicit . to cause the
+	  current directory to be treated as a function directory. 
+01-05-08  A bug in read -n when echo mode was disabled has been fixed.
+01-05-07  A bug in which function definitions could be listed as part
+	  of the history has been fixed.
+01-04-30 +This release uses a new and often much faster pattern matcher than
+	  earlier releases.
+01-04-30 +An optimizer now eliminates invariant parameter expansions from
+	  for while and until loops.
+01-04-30 +The variable .sh.match is set after each pattern match (# % or /)
+	  in a variable substitution.  The variable .sh.match is an
+	  indexed array with element 0 being the complete match. 
+	  The array is only valid until the next subsequent pattern
+	  match or until the value of the variable changes which ever
+	  comes first.
+01-04-30 +A self generating man page has been added to shcomp.  Also,
+	  shcomp now stops compiling when it finds an exit or exec
+	  command and copies the remainder so that it can be used
+	  for standard input.
+01-04-30 +The shcomp command was modified so that it can work in an
+	  EBCIDIC environment and that binary scripts are portable
+	  across environments.
+01-04-30  A bug in the handling of a trailing : in PATH has been fixed.
+01-04-30  A bug in which the builtin version of a command would get invoked
+	  even though the full pathname for the command was specified
+	  has been fixed.
+01-04-30  A bug in which read would loose the last character when
+	  reading the last line of a file that did not contain a new-line
+	  character has been fixed.
+01-04-23  A bug on some systems in which in vi mode the end of file
+	  character and end of line character could be swapped has
+	  been fixed.
+01-04-23  A bug on some systems in which invoking a shell script that
+	  did not have execute permission could set the exit value to
+	  127 rather than 126 has been fixed.
+01-04-20  A bug in which read -n from a pipe would block if fewer than
+	  n characters was received has been fixed.
+01-04-09  A bug in which invalid patterns, for example, ) by itself,
+	  was not treated as a string has been fixed so that if i=')',
+	  then [[ $i == $i ]] is true.
+01-04-09 +The shell arithmetic now interprets C character constants.
+01-04-09  A bug in which a non-zero return from a function defined
+	  with the function reserved word did not trigger the ERR
+	  trap or exit with set -e has been fixed.
+01-04-02  A bug on some systems, in which characters above 127 were
+	  not displayed correctly in vi or emacs edit mode has been fixed.
+01-04-02  A bug on some systems, introduced in the 'k' point release, in
+	  which the erase character in viraw mode was moving the cursor
+	  to the left without erasing the character has been fixed.
+01-04-02  On some systems the wcwith() function was returning a wrong
+	  value for characters and caused characters to be displayed
+	  incorrectly from the shell edit modes.  A work around for
+	  this problem has been added. 
+01-03-26  A bug in which valid scripts could produce syntax errors
+	  when run with locales that considered characters such as "'"
+	  to be space characters has been fixed.
+01-03-20  A bug in which an syntax error in an arithmetic expression
+	  entered interactively could cause the shell to go into
+	  an infinite loop outputting the error message has been fixed.
+01-03-10 +ksh93 accepts -l as a synonym for -L in test on systems for
+	  which /bin/test -l tests for symbolic links.
+01-03-10  A bug in parsing scripts in which { and } are used in place of
+	  in and esac in case statements embedded in compound commands
+	  has been fixed.  Use of { and } for in and esac is obsolete.
+01-03-06  A bug in which an argument of the form foo=bar was not
+	  being passed correctly to a traced function whose name
+	  was foo has been fixed.
+01-03-02  Using $(trap -p name) did not print the name of the current
+	  trap setting for trap name.
+01-02-26  Exported floating point variables gave incorrect results
+	  when passing them to ksh88.  This has been fixed.
+01-02-25  A race condition in which a coprocess which completed too quickly
+	  would not allow subsequent coprocesses to start has been fixed.
+01-02-25  The 'g' format specifier is now handled by printf.  It had
+	  inadvertently been omitted.
+01-02-20  The + was not being displayed during an execution trace
+	  with the += assignment operator.
+01-02-19  The error message which occurs when the interpreter name
+	  defined on the #! line does not exist is more informative.
+01-02-19  A bug in which $0 would not be set correctly when a
+	  script with #! was invoked by full pathname from the
+	  directory of the script has been fixed.
+01-02-19  A shell script did not always pick up tty mode changes
+	  made by external commands such as stty which could
+	  effect the behavior of read.
+01-02-19  The -u, -g, and -k unary tests did not give the correct
+	  results when used with negation and this has been fixed.
+
+01-02-05  --- Release ksh93k+  ---
+01-02-05  The sequence \<newline> inside $'...' was not incrementing
+	  the line count and this has been fixed.
+01-02-05 +Modified expansion of "${@-}" so that if no arguments are set
+	  it results in null string rather than nothing.
+01-02-02  memory leak problem with local variables in functions fixed.
+01-01-25 +allow arithmetic expressions with float%int and treat them
+	  as ((int)float)%int rather than as an error. 
+01-01-19  read -n1 was not working and has been fixed.
+01-01-17 +ksh now handles the case in which a here document in command
+	  substitution $() is terminated by the trailing ).  Previously,
+	  a new-line was needed at the end of the delimiter word. 
+01-01-02  A bug in which a KEYBD trap would cause a multi-line token
+	  to be processed incorrectly has been fixed.
+00-12-10 +Arithmetic integer constants can now have L and U suffices. 
+00-12-10  A bug in the processing of arithmetic expressions with compound
+	  variables when the -n option is on has been fixed.
+00-12-08  A bug in M-f and M-b from emacs mode has been fixed.  This
+	  bug only occurs when ksh93 is compiled without MULTIBYTE enabled.
+00-11-29  A bug in which jobs -p would yield 0 for background
+	  jobs run in a script has been fixed.
+00-11-21  A bug in integer arrays in which the number of elements is
+	  incorrect when the ++ operator is applied to a non-existing
+	  element has been fixed.  For example, integer x; ((x[3]++)).
+00-11-20  A timing bug in which the shell could reset the terminal
+	  group to the wrong value in the case that the a new process
+	  changes the terminal group during startup has been fixed.
+
+00-10-27  --- Release ksh93k  ---
+00-10-27  Using tab for completion now works only when applied
+	  after a non-blank character at the end of the current line.
+	  In other case a tab is inserted.
+00-10-27  A bug in the emacs edit mode for ^X^E has been fixed.
+	  The ^X^E sequence is supposed to invoke the full editor
+	  on the current command.
+00-10-18  A bug in which expansions of the form ${var//pattern/string}
+	  did not work correctly when pattern was '/' or "/" has
+	  been fixed.
+00-10-18 +The output format for indexed arrays in compound variables
+	  has been modified so that it can be used as input.
+00-10-18  Assignments with name references (typeset -n) will now
+	  implicitly unreference an existing name reference.
+00-10-17  A bug the += append operator when a single array element
+	  is appended to a variable that is not an array has been fixed.
+00-10-16  A bug in which the SIGCONT signal was being sent to
+	  each process will kill -0 or kill -n 0 has been fixed.
+00-10-12 +The arithmetic evaluation portion has been rewritten to
+	  perform a number of optimizations.
+00-10-10  A bug in which name prefix matching ${!name.*} was not
+	  checking name to see if it was a name reference has been fixed.
+00-09-26  A bug in the multibyte version in which the width of for
+	  non-printing characters was not correct has been fixed.

+00-09-12  A bug in which multibyte characters would be displayed incorrectly
+	  has been fixed.
+00-08-08  Removed build dependency on iswprint() and iswalph().
+00-07-20  In some cases the read builtin would read more than a single
+	  line from a pipe on standard input and therefore leave the seek
+	  position in the wrong location.
+00-07-05 +If the directory / is on the path, a / will not be inserted
+	  between the directory and the file name during path searching
+	  to avoid searching // for systems that treat this specially.
+00-06-26  A bug in which on rare occasions wait could return before all
+	  jobs have completed has been fixed.
+00-06-21  A bug in which backspace did not work correctly during the
+	  R replace directive in vi-mode has been fixed.

+00-05-09  Modified command substitution to avoid using /tmp files when
+          run on read-only file systems. 
+00-04-17 +Modified printf to handle '%..Xc' and '%..Xs' options where X
+	  is not an alpha character.  Previous versions core dumped with this.
+00-04-10 +Changes to multibyte editing code were made to use standard
+	  ISO C functions rather than methods devised before the standard.
+00-04-09  Add %H options to printf to output strings with <"'&\t> properly

+KSH-93 is the most recent version of the KornShell Language
+described in
+"The KornShell Command and Programming Language,"
+by Morris Bolsky and David Korn of AT&amp;T Bell Laboratories, ISBN 0-13-182700-6.
+The KornShell is a shell programming language,
+which is upward compatible with "sh" (the Bourne Shell),
+and is intended to conform to the IEEE P1003.2/ISO 9945.2 Shell and
+Utilities standard.
+KSH-93 provides an enhanced programming environment in
+addition to the major command-entry features of the BSD
+shell "csh".  With KSH-93, medium-sized programming tasks can be
+performed at shell-level without a significant loss in performance.
+In addition, "sh" scripts can be run on KSH-93 without modification.
+<P>
+The code should conform to the IEEE POSIX 1003.1 standard and to the
+proposed ANSI-C standard so that it should be portable to all
+such systems.  Like the previous version, KSH-88,
+it is designed to accept eight bit character sets
+transparently, thereby making it internationally compatible.
+It can support multi-byte characters sets with some characteristics
+of the character set given at run time.
+<P>
+KSH-93 provides the following features, many of which were also inherent
+in KSH-88:
+<UL type=square>
+<LI>
+Enhanced Command Re-entry Capability:  The KSH-93 history
+function records commands entered at any shell level and stores
+them, up to a user-specified limit, even after you log off.
+This allows you to re-enter long commands with a few keystrokes
+- even those commands you entered yesterday.
+The history file allows for eight bit characters in
+commands and supports essentially unlimited size histories.
+<LI>
+In-line Editing: In "sh", the only way to fix mistyped
+commands is to backspace or retype the line. KSH-93 allows you
+to edit a command line using a choice of EMACS-TC or "vi"
+functions.
+You can use the in-line editors to complete filenames as
+you type them.
+You may also use this editing feature when entering
+command lines from your history file.
+A user can capture keystrokes and rebind keys to customize the
+editing interface.
+<LI>
+Extended I/O Capabilities:  KSH-93 provides several I/O
+capabilities not available in "sh", including the ability to:
+<UL type=circle>
+<LI>
+specify a file descriptor for input and output
+<LI>
+start up and run co-processes
+<LI>
+produce a prompt at the terminal before a read
+<LI>
+easily format and interpret responses to a menu
+<LI>
+echo lines exactly as output without escape processing
+<LI>
+format output using printf formats.
+<LI>
+read and echo lines ending in "&#0092;".
+</UL>
+<LI>
+Improved performance: KSH-93 executes many scripts faster
+than the System V Bourne shell. A major reason for this is
+that many of the standard utilities are built-in.
+To reduce the time to initiate a command, KSH-93 allows
+commands to be added as built-ins at run time
+on systems that support dynamic loading such as System V Release 4.
+<LI>
+Arithmetic: KSH-93 allows you to do integer arithmetic in any
+base from two to sixty-four.  You can also do double
+precision floating point arithmetic.
+Almost the complete set of C language operators are available
+with the same syntax and precedence.
+Arithmetic expressions can be used to as an argument expansion 
+or as a separate command.
+In addition there is an arithmetic for command that works
+like the for statement in C.
+<LI>
+Arrays: KSH-93 supports both indexed and associative arrays.
+The subscript for an indexed array is an arithmetic expression,
+whereas, the subscript for an associative array is a string.
+<LI>
+Shell Functions and Aliases: Two mechanisms - functions and
+aliases - can be used to assign a user-selected identifier to
+an existing command or shell script.
+Functions allow local variables and provide scoping
+for exception handling.
+Functions can be searched for and loaded on first reference the
+way scripts are.
+<LI>
+Substring Capabilities:  KSH-93 allows you to create a
+substring of any given string either by specifying the starting
+offset and length, or by stripping off leading
+or trailing substrings during parameter substitution.
+You can also specify attributes, such as upper and lower case,
+field width, and justification to shell variables.
+<LI>
+More pattern matching capabilities:  KSH-93 allows you to specify
+extended regular expressions for file and string matches.
+<LI>
+KSH-93 uses a hierarchal name space for variables.
+Compound variables can be defined and variables can
+be passed by reference.  In addition, each variable
+can have one or more disciplines associated with
+it to intercept assignments and references.
+<LI>
+Improved debugging:  KSH-93 can generate line numbers on execution
+traces.  Also, I/O redirections are now traced.
+There is a DEBUG trap that gets evaluated before each command
+so that errors can be localized.
+<LI>
+Job Control: On systems that support job control, including
+System V Release 4, KSH-93
+provides a job-control mechanism almost identical to that of
+the BSD "csh", version 4.1.
+This feature allows you
+to stop and restart programs, and to move programs between the
+foreground and the background.
+<LI>
+Added security:
+KSH-93 can execute scripts which do not have read permission
+and scripts which have the setuid and/or setgid set when
+invoked by name, rather than as an argument to the shell.
+It is possible to log or control the execution of setuid and/or
+setgid scripts.
+The noclobber option prevents you from accidentally erasing
+a file by redirecting to an existing file.
+<LI>
+KSH-93 can be extended by adding built-in commands at run time.
+In addition, KSH-93 can be used as a library that can
+be embedded into an application to allow scripting.
+</UL>
+Documentation for KSH-93 consists of an "Introduction to KSH-93",
+"Compatibility with the Bourne Shell" and a manual page and a
+README file.  In addition, the "New KornShell Command and Programming
+Language," book is available from Prentice Hall.

+12-02-29  --- Release ksh93u+ ---
+12-02-29  A bug which could lead to a core dump when more that four shared
+	  libraries were added with the builtin command has been fixed.
+12-02-29  Fixed a few bugs which caused SIGCHLD to be blocked preventing
+	  background jobs from being reaped until a foreground job was run.
+12-02-27  A bug in which sh -c for a simple command caused a fork() has been
+	  fixed.
+12-02-27  A timing bug on systems such as AIX that doesn't support vfork()
+	  that could cause the exist status to get lost has been fixed.
+12-02-22  A private file descriptor that was not close-on-exec for a command
+	  substitution and has been fixed.
+12-02-14  A bug in which ^Z did not stop a pipeline when the last component
+	  was a shell built-in has been fixed.
+12-02-14  getconf("PATH") used to initialize ed(1) path.
+12-02-13 +In earlier version read from standard input would fail when called
+	  from the KEYBD trap.  Now read options -N, -n, and -t should work
+	  when called from a KEYBD trap.
+12-02-13  If FCEDIT is not set and fc is invoked without the -e option,
+	  ed will be invoked if found instead of /bin/ed. 
+12-02-10  Another bug in the saving and restoring of IFS in a subshell
+	  that caused a core dump has been fixed.
+12-02-08  A bug in which .sh.fun disciplines could be cleared after a
+	  function completes has been fixed.
+12-02-08  A bug in job control in which the foregroup process group was not
+	  set correctly after restarting a stopped pipeline has been fixed.
+12-02-07  A bug in which numbers with leading zeros could be treated as
+	  octal constants outside of ((...)) has been fixed.
+12-02-06  A bug in arithmetic with compound variables containing multiple
+	  array elements has been fixed.
+12-02-02  A bug in the ulimit option table was fixed.
+12-01-26  A bug in which a set command that did not change monitor could
+	  effect the behavior of the monitor when monitor mode is on is fixed.
+12-01-21 +You can now test whether the shell implements a math function using
+	  typeset -f .sh.math.name, where name is the name of the function.
+12-01-21  A bug in which typeset -L and typeset -R did not handle multibyte
+	  characters correctly has been fixed.
+12-01-20  A bug that could cause the shell to hang waiting for an incorrect
+	  job pid has been fixed.
+12-01-19  A memory leak which occured for a nested command subtiution has been
+	  fixed.
+12-01-17  A bug in which typeset -u PS1 could enable the uppercase attribute
+	  for some other variables, for exampe, HISTFILE has been fixed.
+12-01-16  A bug in which .sh.match was not correct after a substring match when
+	  the replacement string contained a substring match has been fixed.
+12-01-12 +Files that are sourced from profile files are now read and executed
+	  one command at a time so that alias definitions take effect as they
+	  do for profile files.
+12-01-12  A bug in which whence -p would find a function if one existed and
+	  there was no command of that name on PATH.
+12-01-11  Change b_* prototype (int, char**, void*) =&gt; (int, char**, Shbltin_t*).
+12-01-05  A bug in which read was not terminating for a signal that had a trap
+	  set has been fixed.
+12-01-01  A timing problem with &gt;; has been fixed.
+12-01-01  A macro expansion memory leak has been fixed.
+11-12-26  A bug in array assignments of the form arr=( $arr&#0091;i&#0093; ...) in which
+	  arr was not unset before the assignment has been fixed. 
+11-12-20  A number of code changes were made based on the results of errors
+	  indicated by static code analysis.
+11-12-13  In vi edit mode a lteral &lt;TAB&gt; can now be entered by preceding it
+	  with a backshash.
+11-12-13  When tab is entered for completion after a ' or ", the ' and "
+	  characters are no longer deleted.
+11-12-07  A bug in which a program in the current direcotry with a . in the
+	  name could fail to execute when both PATH and FPATH end with :. has
+	  been fixed.
+11-12-07  I fixed a bug in which a variable expansion in a large here-document
+	  could be expanded to a null string.
+11-12-06  An optimization to read was added in the case the the read command
+	  was redirected from a file.
+11-12-06  Changes were made to make the line limit for read unlimited by
+	  default.
+11-12-05  A bug in which unsetting an array variable did not completely clear
+	  the variable in some cases has been fixed.
+11-12-02 +The printf alternative character # when applied to the %q format will

+10-05-21  A bug in which using $var inside ((...)) did not work when var was
+	  a hex float variable.
+10-05-20 +The compile option SHOPT_EDPREDICT has been added.  When this option
+	  is on, as you type a line beginning with a # the following characters
+	  are treated as a shell pattern and cause matching lines from the
+	  history file to be displayed as a numbered list as you type.
+	  You can scroll up and down this list or you can use &lt;ESC&gt;nTAB
+	  to make this the current line (n defaults to 1 of omitted) or
+	  &lt;ESC&gt;n&lt;cr&gt; to execute.
+10-05-20  A bug which caused an exception when multiple levels of composite
+	  functions in arithemtic expressions has been fixed.

+	  elements followed by an expansion ${bar.foo&#0091;a&#0093;} and an assignment
+	  bar.foo&#0091;a&#0093;=b, no longer indicates that ${#bar.foo&#0091;@&#0093;} has 0 members.

+	  the subshell completed has been fixed.
+10-04-23  For file completion in commmand line editing, file names starting
+	  with # are now escaped so that they are not treated as comments.

+	  variable, could assign value to the type variable rather than to
+	  the type instance has been fixed.

+	  fail to compile with shcomp has been fixed.
+10-04-15 +Job pools have been added with the SHOPT_COSHELL compilation option.
+	  A job pool allows a collection of background jobs to run either locally 
+	  or remotely and to be managed as a unit.  The command '&amp; name ...'
+	  creates or uses a named job pool for subsequent background jobs.
+	  kill, wait, and jobs allow the pool name as operands.
+10-04-14  A bug in which a coprocess connection could terminate prematurely
+	  when running a nested subshell has been fixed.
+10-04-12 +Enumeration constants can be used in arithmetic expressions with the
+	  ==, != and = operators when the left hand side is an enum variable
+	  and the right hand side is an enumeration constant.

+	  'function .sh.math.name x y z{...}' , where name is the function name
+	  invoked within ((...)) and x y z are long double arguments passed
+	  as name references.  y and z are used for functions with two and
+	  three arguments respectively.  The value of the function is the value
+	  of the long double .sh.value variable when the function returns.
+10-03-24  A bug in which integer division was mistakenly used when the
+	  numerator was a binary operator with the first operand floating
+	  point and the second integer, e.g. (.1**3)/3, has been fixed.

+	  fixed.
+10-03-19  Removed space between Stopped message and (SIGTTIN) and (SIGTTOUT).
+10-03-17  Modified profile shell execution so that when builtins that
+	  correspond to executable have extended attributes, they are
+	  executed by pfksh instead of being treated as built-ins.
+10-03-16  A bug in whence -a which produced duplicate lines of output has
+	  been fixed.
+10-03-16  A bug in the handling of process groups in monitor mode for
+	  command substitutions has been fixed.

+10-03-15 +Modified the shell I/O so that the shell will not fail if the
+	  ulimit for open_max is increased as part of the script.
+10-03-12  A bug in which a here-document containing command substitutions
+	  that contained here-documents did not process correctly has been
+	  fixed.

+	  leave a file descriptor open has been fixed.
+09-03-24 +ksh now only uses the value of the _ variable on startup if it can
+	  verify that it was set by the invoking process rather than being
+	  inherited by some other ancestor.
+09-03-24 +When ksh is invoked without -p and ruid!=euid, and the shell is
+	  compiled without SHOPT_P_UID or ruid&lt;SHOPT_P_UID, the shell now

+	  been fixed.
+08-05-07 +The typeset -S option was added for variables outside type
+	  definitions to provide a storage class similar to C static
+	  inside a function defined with function name.  When outside
+	  type definitions and outside a function, the -S option cause
+	  the specified variable so be unset before the assignment and
+	  before the remaining attributes are supplied.

+07-07-09  A bug in which typeset -a did not list indexed arrays has been
+	  fixed.
+07-07-03 +The command substitution ${ command;} has been added.  It behaves

+	  with a redirection and not occurring with in the while, until, if,
+	  select condition can be preceded by a semi-colon which will
+	  be ignored when showme is off.  When showme is on, any command
+	  preceded by a colon will be traced but not executed.
+06-08-16 +As a new feature, a leading ~(N) on a pattern has no effect 
+	  except when used for file expansion.  In this case if not
+	  matches are found, the pattern is replaced by nothing rather
+	  than itself.
+06-08-11  A bug in the expansion of ${.sh.match&#0091;i&#0093;:${#.shmatch&#0091;i&#0093;}} has

+          the size as characters rather than bytes unless storing into a
+	  binary (typeset -B) variable.
+06-07-27 +When the here document operator &lt;&lt; is followed directly by a #
+	  rather than a -, the first line of the here-document determines

+	  selected when either /bin or /usr/bin is scanned.
+06-06-04 +Added literal-next character processing for emacs/gmacs mode. 
+	  This change is not compatible with earlier versions of ksh93
+          and ksh88 when the stty lnext is control-v.  The sequence
+	  escape-control-v will display the shell version.
+06-05-31 +Modified emacs and vi mode so that entering a TAB after a partial
+	  TAB completion, generates a listing of possible completions.
+	  After the second TAB, a number followed by a TAB will perform
+	  the completion with the corresponding item.
+06-05-19 +Modified arithmetic so that conversions to strings default to
+	  the maximum number of precision digits.
+06-05-16  Bug fixes for multibyte locales. 
+06-05-10  The =~ operator was added to &#0091;&#0091;...&#0093;&#0093; and  &#0091;&#0091; string ~= ERE &#0093;&#0093;
+	  is equivalent to &#0091;&#0091; string == ~(E)ERE &#0093;&#0093;.

+	  with function  name could not be used with compound variables has
+	  been fixed.

+	  (output) pipe to close before reading from (after writing to)
+          it has been fixed.
+06-02-28  A bug in which stopping a job created with the hist builtin command

+05-12-13  An arithmetic bug in which x+=y+=z was not working has been fixed. 
+05-12-13  An arithmetic bug in which x||y was returning x when x was non-zero
+	  rather than 1 has been fixed.

+	  -li and -lE to handle long long and long double types.
+05-12-07 +The histexpand (-H) option has been added which allows C-shell
+	  style history expansions using the history character !.
+05-12-07 +The multiline option was added which changes that way the edit
+	  modes handle lines longer than the window width.  Instead of
+	  horizontal scrolling, multiple lines on the screen are used.
+05-12-05  The whence builtin now returns an absolute pathname when the
+          command is found in the current directory.
+05-11-29  A bug which caused ksh -c '&#0091;&#0091; ! ((' to core dump rather than
+	  report a syntax error has been fixed.

+	  with the new I/O redirection operators, &lt;#  and &gt;#.  Currently,
+	  these redirection operators must be followed by ((expr))
+	  but in a future release, it should be able to used to seek forward

+	  new-line is not treated as a space delimiter, only a single
+	  new-line is deleted at the end of a command substitution.
+05-08-19 +When a tilde substitution expands to the / directory and is
+	  followed by a /, it is replaced by the empty string.
+05-08-16  A bug in which n&lt;&amp;m did not synchronize m has been fixed.

+	  caused the input line to shift left/right has been fixed.
+05-06-24  A race condition which could cause the exit status to get lost
+	  on some fast systems has been fixed.
+05-06-21  A bug in which nested patterns of the form {m,n}(pat) would cause
+	  syntax errors has been fixed.
+05-06-21  A bug in the macro expander has been fixed which could cause a
+          syntax error for an expansion of the form ${x-$(...)} when
+	  x is set and the command substitution contained certain strings.
+05-06-08 +On systems for which echo does not do System V style &nbsp;expansions,
+	  the -e option was added to enable these expansion.
+05-06-08  A bug in which ${var op pattern} to not work when inside an
+	  arithmetic expression has been fixed.
+05-05-23 +An extension to shell patterns that allows matching of nested
+	  groups while skipping over quoted strings has been added.
+05-05-18  A bug in which the line number for errors was not correct for
+          functions loaded from FPATH has been fixed.
+05-04-18  A bug in which the exit status $? is not set when a trap triggered
+	  by the &#0091;&#0091;...&#0093;&#0093; command is executed has been fixed.
+05-04-08 +Redirection operators can be directly preceded with {varname}
+	  with no intervening space, where varname is a variable name which
+	  allows the shell to select a file descriptor &gt; 10 and store it
+	  into varname.
+05-04-08 +SHOPT_CMDLIB_BLTIN=1 now includes &lt;cmdlist.h&gt; generated table.
+05-04-07 +&#0091;&#0091; -o ?option &#0093;&#0093; is true if "option" is a supported option.
+05-04-05  A bug in handling file completion with spaces in the names
+          has been fixed.
+05-03-25 +The SIGWINCH signal is caught by default to keeps the LINES and
+	  COLUMNS variables in sync with the actual window size.
+05-03-25 +Building ksh with SHOPT_REMOTE=1 causes ksh to set --rc if stdin is
+	  a socket (presumably part of a remote shell invocation.)
+05-03-25 +Building ksh with SHOPT_SYSRC=1 causes interactive ksh to source
+	  /etc/ksh.kshrc (if it exists) before sourcing the $ENV file.
+05-03-25 +{first..last&#0091;..incr&#0093;&#0091;%fmt&#0093;} sequences added to brace expansions
+	  when braceexpand is enabled.
+05-03-03  A bug where a SIGCHLD interrupt could cause a fifo open to fail has
+	  been fixed.
+05-02-25  A bug in which a builtin command run in the background could
+	  keep a file descriptor open which could cause a foreground

+05-02-24  A bug where builtin library commands (e.g., date and TZ) failed to
+	  detect environment variable changes has been fixed.
+05-02-22 +The read builtin and word splitting are now consistent with respect
+	  to IFS -- both treat IFS as field delimiters.
+05-02-22 +The read builtin no longer strips off trailing delimiters that
+	  are not space characters when there are fewer variables than fields.
+05-02-17  A builtin bug on systems where dlsym(libcmd) returns link-time
+	  bindings has been fixed.
+05-02-12  A bug in which the lib_init() function for .paths BUILTIN_LIB
+	  libraries was not called has been fixed.
+05-02-06  A bug on some systems in which moving the write end of a co-process
+	  to a numbered file descriptor could cause it to close has been fixed.

+
+05-01-11  --- Release ksh93q  ---
+05-01-11  A bug in the integral divide by zero check has been fixed.
+05-01-11 +The -l option has been added to read /etc/profile and
+	  $HOME/.profile, if they exist, before the first command.
+05-01-11  An argument parsing bug that caused `kill -s x -- n' to fail has
+	  been fixed.
+05-01-11 +The .paths file, introduced in ksh93m, which can appear in
+	  any directory in PATH, now allows a line of the form 'BUILTIN_LIB=.'
+	  When a command is searched for this directory, and the full path
+	  matches the path of the built-in version of the command (listed
+	  by the 'builtin' command) then the built-in version of the command
+	  is used.  When ksh is built with SHOPT_CMDLIB_DIR=1 then all libcmd
+	  functions become builtins with the '/opt/ast/bin/' directory prefix.
+05-01-10  A bug in which a nameref to a compound name caused a core dump has
+	  been fixed.
+05-01-09  A bug in which some SIGCHLD interrupts (from child processes exiting)
+	  caused a fatal print/echo error diagnostic has been fixed.
+04-12-24  A bug in which some SIGCHLD interrupts (from child processes exiting)
+          corrupted the internal process/job list, sometimes causing the shell
+	  to hang, has been fixed.
+04-12-01  A bug in which typeset -Fn truncated less than n digits for large
+	  numbers has been fixed.
+04-11-25  A bug in which standard error could be closed after a redirection
+	  to /dev/stderr has been fixed.
+04-11-17  A bug in which an expansion of the form ${array&#0091;@&#0093;:3} could expand
+          to ${array&#0091;0&#0093;} when ${array&#0091;3&#0093;} was not set has been fixed.
+04-10-22 +The -E or -orc command line option reads ${ENV-$HOME/.kshrc} file.
+04-10-22 +`-o foo' equivalent to `+o nofoo', `-o nobar' equivalent to `+o bar'.
+          `--foo' equivalent to `-o foo', `--nofoo' equivalent to `+o foo'
+04-10-05 +The .paths file, introduced in ksh93m, which can appear in
+	  any directory in PATH, now allows a line of the form
+	  'BUILTIN_LIB=libname'.  When a command is searched for this directory,
+	  the shared library named by libname will first be searched for a
+	  built-in version of the command.
+04-09-03  &lt;&lt;&lt; here documents now handle quotes in the word token correctly. 
+04-08-08 +The maximum size for read -n and and read -N was increased from
+	  4095 to 32M.
+04-08-04 +printf %q was modified so that if an no operand was supplied, no
+	  no output would be generated rather than a quoted empty string.
+04-08-01 +The -n and -N options of the read builtin has been modified
+	  when reading variables with the binary attribute so that the
+	  data is stored directly rather than through assignment.
+04-08-01 +The shcomp command has been modified to process alias commands
+	  under some conditions.
+04-07-31 +The .sh.match variable added in ksh93l, now works like other
+	  indexed arrays.
+04-07-08  A loop optimizer bug which occurs when typeset is used in
+	  a for or while loop inside a function has been fixed.
+04-06-24 +The number of subexpressions in a pattern was increased to 64
+	  from the current number of 20.
+04-06-17 +The -t option to read was modified to allow seconds to be
+	  specified as any arithmetic expression rather than just
+	  an integral number of seconds, for example even -t 'sin(.5)'
+	  is now valid.
+04-06-16  Two small memory leak problems were fixed.
+04-06-15  A bug in ${var/pattern/"string"} which occurred when string
+	  contained pattern matching characters has been fixed.
+04-05-08  printf $'%d produced an erroneous error message and has
+	  been fixed.
+04-05-24  A bug in which an associative array without any elements could
+	  cause a core dump when a script with an associative array with
+	  the same name was declared in a script invoked by name has
+	  been fixed.
+04-05-11  A bug in which an exec statement could close the script that
+	  is being processed in a script that is run by name causing
+	  a failure has been fixed.
+04-04-28 +If the first character of assignment to an integer variable was 0,
+          the variable had been treated as unsigned.  This behavior was
+          undocumented and has been removed.
+04-04-05  A bug in which the positioning of standard input could be incorrect
+	  after reading from standard input from a subshell has been fixed.
+04-03-30  A bug in the for loop optimizer which in rare cases could cause
+	  memory corruption has been fixed.
+04-03-29 +The preset alias source='command .' has been added.
+04-03-29  A bug introduced in ksh93p on some systems in which invoked by
+	  name with #! on the first line would not get the signals handling
+	  initialized correctly has been fixed. 
+04-03-29  A bug introduced in ksh93p in which a HUP signal received by
+	  a shell that is a session group leader was not passed down to
+	  its children has been fixed.
+
+04-02-28  --- Release ksh93p  ---
+04-02-28 +The ability to apply an append discipline to any variable has
+	  been added.
+04-02-14  A bug in which the exportall option (set -a) would cause incorrect
+	  results for arrays has been fixed.
+04-02-02  A bug in which an exported array would pass more than
+	  the first element to a script invoked by name has been fixed.
+04-02-02  A bug on some systems in which name=value pairs preceding a script
+	  invoked by name was not getting passed to the script has been fixed.
+04-01-20  A bug in which an unset discipline function could cause a core
+	  dump on some systems has been fixed.
+04-01-12  A bug in which a continue or break called outside a loop from
+	  inside a function defined with name() syntax could affect 
+	  the invoking function has been fixed.
+04-01-08  If a command name begins with ~, only filename completion will be
+	  attempted rather than pathname completion using the builtin editors. 
+04-01-08  A bug in the vi edit mode in which the wrong repeat count on
+	  multiple word replacements with the . directive has been fixed.
+04-01-06  Backspace characters are now handled correctly in prompt strings.
+04-01-06 +The getopts builtin has been modified to accept numerical
+	  arguments of size long long on systems that support this.
+04-01-06  A bug in which unsetting all elements of an associative array
+	  would cause it to be treated as an indexed array has been fixed.
+03-12-15  A bug in which a quoted string ending with an unescaped $ would
+	  delete the ending $ in certain cases has been fixed.
+03-12-05  A bug in which the shell could hang when set -x tracing a command
+	  when an invalid multibyte character is encountered has been fixed. 
+03-12-05  On some systems, if the KEYBD trap is set, then commands that use
+	  the meta key were not processed until return was hit.  This
+	  has been fixed.
+03-12-05  A problem which occurred when the login shell was not a group
+	  leader that could cause it to fail has been fixed.
+03-12-05  A problem in which a shell could core dump after receiving a signal
+	  that should cause it to terminate while it was in the process
+	  of acquiring more space has been fixed.
+03-12-05 +If ENV is not specified, the shell will default to $HOME/.kshrc
+	  for interactive shells.
+03-11-21  A bug introduced in ksh93o in which the DEBUG trap could get
+	  disabled after it triggered has been fixed. 
+03-11-04  A bug in which using arithmetic prefix operators ++ or -- on a
+	  non-lvalue could cause a core dump has been fixed.
+03-11-04  A bug in which leading zeros were stripped from variable
+	  expansions within arithmetic computation to avoid being treated
+	  as octal constants when they should not have, has been fixed.
+03-10-08  A bug introduced in ksh93o in which a large here document inside
+	  a function definition could get corrupted has been fixed.
+03-09-22  A bug in which the .get discipline function was not being
+	  called when a string variable was implicitly referenced from
+	  within a numerical expression has been fixed.
+03-09-22  A bug in which a script without a leading #! could get executed
+	  by /bin/sh rather than the current shell on some systems has
+	  been fixed.
+03-09-12 +To improve conformance with ksh88, leading zeros will be ignored
+	  when getting the numerical value of a string variable so that
+	  they will not be treated as octal constants.
+03-09-03 +The builtin kill command now processes obsolete invocations
+	  such as kill -1 -pid.
+03-09-02  The restriction on modifying FPATH in a restricted shell (sh -r)
+	  has been documented.
+03-09-02 +The restricted shell (sh -r) has been modified to disallow
+	  executing command -p.
+03-08-07  A bug in which the KEYBD trap was not being invoked when
+	  characters with the 8th bit set has been fixed.
+03-08-02  A parser bug introduced in ksh93o which caused the character
+	  after () in a Posix function definition to be skipped 
+	  when reading from standard input has been fixed.
+03-08-01  A bug in which "${foo#pattern}(x)" treated (x) as if it were
+	  part of the pattern has been fixed.
+03-08-01 +The command -x option has been modified so that any trailing
+	  arguments that do expand to a single word will be included
+	  on each invocation, so that commands like command -x mv * dir
+	  work as expected.
+
+03-07-20  --- Release ksh93o+  ---
+03-07-20  A bug in which could cause memory corruption when a posix
+	  function invoked another one has been fixed.
+03-07-15  A bug in which a file descriptor&gt;2 could be closed before
+	  executing a script has been fixed.
+03-07-15  A parsing error for &lt;() and &gt;() process substitutions inside
+	  command substitution has been fixed.
+03-07-15  A parsing error for patterns of the form {...}(...) when
+	  used inside ${...} has been fixed.
+03-07-15  An error in which expanding an indexed array inside a compound
+	  variable could cause a core dump has been fixed.
+03-07-15  A bug in which on rare occasions a job completion interrupt
+	  could cause to core dump has been fixed.
+03-06-26  A bug in which process substitution embedded within command

+	  were no arguments has been fixed.
+03-96-23  A bug in which ${X&#0091;@&#0093;:offset:len} could core dump when X
+	  was unset has been fixed.
+03-06-22 +The -x option was added to the command builtin.  If this
+	  option is on, and the number of arguments would exceed ARG_MAX,
+	  the command will be invoked multiple times with a subset of
+	  the arguments.  For example, with alias grep='command -x grep,
+	  any number of arguments can be specified.
+03-06-14  A bug in which could cause a core dump on some systems with
+	  vi and emacs editors with the MULTIBYTE option has been fixed.
+03-06-06  A bug in which the shell could core dump when a script was
+	  run from its directory, and the script name a symlink to a file
+	  beginning with .., has been fixed.
+03-06-05  A bug in which the shell could core dump when a child process
+	  that it is unaware of terminates while it is calling malloc()
+	  has been fixed.
+03-06-02 +An option named globstar (set -G) has been added.  When enabled,
+	  during pathname expansion, any component that consists only of ** is
+	  matches all files and any number of directory levels.
+03-05-30  A bug in which the PATH search could give incorrect results when
+	  run from directory foo and PATH contained .:foo:xxx has been fixed.
+03-05-29 +Some changes were made to the code that displays the prompt in edit 
+	  mode to better handle escape sequences in the prompt.
+03-05-27  I added = to the list of characters that mark the beginning of
+	  a word for edit completion so that filenames in assignments
+	  can be completed.
+03-05-20  A bug in which read -N could hang on some systems when reading
+	  from a terminal or a pipe has been fixed.
+03-05-19  A bug in which the output of uname from a command substitution
+	  would go to the standard output of the invoking command when
+	  uname was invoked with a non-standard option has been fixed.
+03-05-19  A job control bug which would cause the shell to exit because 
+	  it hadn't take back the terminal has been fixed.  The bug
+	  could occur when running a function that contained a pipeline
+	  whose last element was a function.
+03-05-19  A job control timing bug introduced in ksh93o on some systems
+	  which could cause a pipeline to hang if the first component
+	  completed quickly has been fixed.
+03-05-13 +The read builtin has been modified so that the builtin editors
+	  will not overwrite output from a previous incomplete line. 
+03-05-13  A bug in which the name of an identifier could have the string
+	  .sh. prefixed to it after expanding a variable whose name begins
+	  with .sh. has been fixed.
+03-05-13  A bug in the expansion of $var for compound variables in which
+	  some elements would not be output when the name was a prefix
+	  of another name in the compound variable has been fixed.
+03-05-08  The last item in the ksh93o release on 03-01-02 has been
+	  altered slightly to preserve the leading 0's when the
+	  preceding character is a digit.  Thus, with typeset -LZ3 x=10,
+	  $(( 1$x)) will be 1010 whereas $(( $x) will be 10.
+03-04-25  A bug in which if x is a name reference, then nameref y=x.foo
+	  did not follow x has been fixed.
+
+03-03-18  --- Release ksh93o  ---
+03-03-18 +A -N unary operator was added to test and &#0091;&#0091;...&#0093;&#0093; which returns
+	  true if the file exists and the file has been modified since it
+	  was last read.
+03-03-18 +The TIMEFORMAT variable was added to control the format for
+	  the time compound command.  The formatting description is
+	  described in the man page.
+03-03-06 +A -N n option was added to read which causes exactly n bytes
+	  to be read unlike -n n which causes at most n bytes to be read.
+03-03-03 +Three new shell variables were added.  The variable .sh.file
+	  stores the full pathname of the file that the current command
+	  was found in.  The variable .sh.fun names the current function
+	  that is running.  The variable .sh.subshell contains the depth
+	  of the current subshell or command substitution.
+03-03-03 +When the DEBUG trap is executed, the current command line after
+	  expansions is placed in the variable .sh.command.  The trap
+	  is also now triggered before each iteration of a for, select,
+	  and case command and before each assignment and redirection.
+03-02-28 +Function definitions are no longer stored in the history file so
+	  that set -o nolog no longer has any meaning.
+03-02-28 +All function definitions can be displayed with typeset -f not
+	  just those stored in the history file.  In addition, typeset +f
+	  displays the function name followed by a comment containing the
+	  line number and the path name for the file that defined this function.
+03-02-28  A bug in which the value of $LINENO was not correct when executing
+	  command contained inside mult-line command substitutions has been
+	  fixed.
+03-02-19 +Since some existing ksh88 scripts use the undocumented and
+	  unintended ability to insert a : in front of the % and # parameter
+	  expansion operators, ksh93 was modified to accept :% as equivalent
+	  to % and :# as equivalent to # with ${name op word}.
+03-02-14  A bug which could cause a core dump when reading from standard
+	  error when standard error was a pty has been fixed.
+03-02-14 +The shell arithmetic was modified to use long double on systems
+	  that provide this data type.
+03-02-09  A bug in which a function located in the first directory in FPATH
+	  would not be found when the last component of PATH was . and the
+	  current directory was one of the directories in PATH has been fixed.
+03-02-07 +The trap and kill builtin commands now accept a leading SIG prefix
+	  on the signal names as documented.
+03-02-05  A bug in the expansion of ${var/$pattern}, when pattern contained
+	  \&#0091; has been fixed.
+03-02-05  A bug in which .sh.match&#0091;n&#0093;, n&gt;0, was not being set for substring
+	  matches with % and %% has been fixed.
+03-01-15  A bug in which getopts did not work for numerical arguments specified
+	  as n#var in the getopts string has been fixed.
+03-01-09  A bug in which using ${.sh.match} multiple times could lead to
+	  a memory exception has been fixed.
+03-01-06  A bug in the expansion of ${var/pattern/$string} in the case that
+	  $string contains \digit has been fixed. 
+03-01-02 +A -P option was added for systems such as Solaris 8 that support
+	  profile shell.
+03-01-02  For backward compatibility with ksh88, arithmetic expansion
+	  with ((...)) and let has been modified so that if x is a zero-filled
+	  variable, $x will not be treated as an octal constant.
+
+02-12-05  --- Release ksh93n+  ---
+02-11-30  A bug that can show up in evaluating arithmetic statements that
+	  are in an autoloaded function when the function is autoload from
+	  another function has been fixed.
+02-11-30  An optimization bug in which an expansion of the form ${!name.@},
+	  which occurred inside a for or a while loop, when name is a name
+	  reference, has been fixed.
+02-11-18  A bug in which modifying array variables in a subshell could leave
+	  side effects in the parent shell environment has been fixed.
+02-11-18  A memory leak when unsetting an associative array has been fixed.
+02-11-14 +The code to display compound objects was rewritten to make
+	  it easier for runtime extensions to reuse this code.
+02-11-14 +A change was made to allow runtime builtins to be notified when
+	  a signal is received so that cleanup can be performed.
+02-10-31 +User applications can now trap the ALRM signal.  Previously,
+	  the ALRM signal was used internally and could not be used
+	  by applications. 
+02-10-31  A bug in which signals received while reading from a coprocess
+	  for which traps were set was not handled correctly has been fixed.
+02-10-31  A bug in which a file opened with exec inside a subshell could
+	  be closed before the subshell completed has been fixed.
+02-10-21  A bug in which setting PATH or FPATH inside a function might not
+	  take effect has been fixed.
+02-10-21  A bug which could cause a core dump when a local SECONDS variable
+	  is defined in a function has been fixed.
+02-10-15  A bug in which the associate array name operator ${!array&#0091;@&#0093;}
+	  could return the same name multiple times has been fixed.
+02-10-15  A bug in which the zero'th element of an associative array was
+	  not getting set when an assignment was made without a subscript
+	  specified has been fixed.
+
+02-09-30  --- Release ksh93n  ---
+02-09-30 +The maximum indexed array size was increased to 16Megs.
+02-09-30  A bug which could cause a core dump when changing attributes
+	  of associative array has been fixed.
+02-09-30  A bug in which exporting an array variable would not export the
+	  0-th element has been fixed.
+02-09-30  A bug in which an array assignment of the form a=($a ...) would unset
+	  'a' before the right hand side was evaluated has been fixed.
+02-09-27  A bug in which the error message for ${var?message} when var was
+	  null or unset did not contain the variable name var has been fixed.
+02-09-27  A bug in which closing file descriptors 0 through 2 could
+	  cause a subsequent here document to fail has been fixed. 
+02-09-14  A bug in whence which occurs when the specified name contained
+	  a / has been fixed.
+02-09-14  A bug in the parser for strings of the form name$((expr))=value
+	  has been fixed.
+02-09-14  A for loop optimization bug in which the number of elements in
+	  an array was treated as an invariant has been fixed.
+02-09-09  A bug in which redirection or closing of a file descriptor between
+	  3 and 9 could cause a subsequent here document to fail has been
+	  fixed. 
+02-09-09  A bug in which a background job was not removed from the job list
+	  when a subshell completed has been fixed, for example (prog&amp;). 
+02-09-03  A bug in which an assignment of the form name=(integer x=3)
+	  could be interpreted as an array assignment rather than a
+	  compound variable assignment has been fixed.
+02-08-19  A command completion bug which occurred on file systems that
+	  are case insensitive has been fixed.
+02-08-19  A bug which could lead to an exception on some systems (for
+	  example FREEBSD) which occurred when setting PATH has been fixed.
+02-08-11  A bug in arithmetic rounding in which a value input as a decimal
+	  string would output as a rounded version of the string has
+	  been fixed.
+02-08-11  A bug in which the last character could be deleted from shell
+	  traces and from whence when called from a multibyte locale
+	  has been fixed.
+02-08-01  A bug which could cause a core dump to occur when a shell script
+	  is executed while a coprocess is running that has closed the
+	  output pipe has been fixed.
+02-08-01  A bug in which command completion in multibyte mode could
+	  corrupt memory for long command lines has been fixed.
+
+02-06-17  --- Release ksh93n-  ---
+02-06-17  A bug in which user defined macros could cause a core dump in
+	  with MULTIBYTE mode has been fixed.
+02-06-17  A bug in which printf format specifiers of the form %2$s were causing
+	  a core dump has been fixed.
+02-06-17  A bug in which setting stty to noecho mode did not prevent the
+	  echoing of characters by ksh when emacs or viraw mode
+	  was enabled has been fixed.
+02-06-17  A bug in which background job completion could cause the sleep
+	  builtin to terminate prematurely has been fixed.
+02-06-17  A bug in which the shell could core dump if getopts was called
+	  when the OPTIND variable contained a negative value has been fixed. 
+02-06-10 +The edit mode prompt has been modified to handle escape sequences.  
+02-06-10  A bug which occurred for interactive shells in which the builtin
+	  cat command was used in command substitution on a file whose
+	  size was larger than PIPE_BUF has been fixed.
+02-06-10  A bug in which the trap on ERR was not being processed when
+	  set inside a function has been fixed.
+02-06-07  A bug in which function definitions could cause the history count
+	  to be decremented by one (and even become negative) has been fixed.
+02-06-05  A bug in read in which share mode could be enabled has been fixed.
+02-05-28  A bug which could occur when the last command of a script was
+	  a case statement and the action selected ended in ;&amp; instead of ;;
+	  has been fixed.
+02-05-23  A bug with unary + introduced in ksh93k has been fixed.
+02-05-07  A bug in substitutions of the form ${var/pattern/string} in which
+	  a backslash was inserted in the replacement string when it contained
+	  a special pattern character has been fixed.
+02-05-01  A bug in the emacs edit mode which occurred in versions compiled
+	  for multibyte character sets which occurred when a repeated search
+	  was requested after a long line had been returned for the previous
+	  search has been fixed.
+02-04-02 +vi and emacs edit modes were modified so that tab completion is
+	  disabled when invoked from the read built-in.
+
+02-03-26  --- Release ksh93m+  ---
+02-03-26  A bug in which &nbsp;was not handled correctly when used in file
+	  expansion has been fixed.
+02-02-18  A bug in which lines beginning with a # were deleted from here
+	  documents when the here-document delimiter was followed by
+	  a comment has been fixed.
+02-12-06  An optimization bug in which ${!x&#0091;@&#0093;) was treated as invariant in
+	  a for loop has been fixed.
+02-02-06  A bug in which the ERR trap is not cleared for a script invoked
+	  by name from within a function has been fixed.
+02-01-08  A bug in which a shell script executed from within a subshell
+	  could cause this script to have an invalid pointer leading
+	  to a memory fault has been fixed. 
+02-01-07 +Added here documents of the form &lt;&lt;&lt; word (as per zsh) which
+	  is equivalent to &lt;&lt; delimordelim.
+02-01-07  A bug in which the first word of a compound assignment,
+	  x=(word ...), was treated as a reserved word has been fixed.
+02-01-07  A bug in the handling of &nbsp;when noglob was enabled and a
+	  substitution of the form ${word op pattern} occurred in the
+	  same word has been fixed.
+02-01-07 +A compilation option, CMDLIB_BLTIN in the file OPTION, has
+	  been added.  When this options is set, all commands implemented
+	  in libcmd become shell builtin commands by default.
+02-01-07  A bug in which builtin foo, where foo is already a builtin
+	  would result in the builtin foo getting removed has been fixed. 
+02-01-07  A bug which the shell executed a command found in the current
+	  directory when PATH have no valid directories has been fixed.
+01-11-28  The value of $? was not being set when called with exit.
+01-11-28  If the last command was of the form (...) and a trap on EXIT or
+	  ERR was set, and the command inside () modified the trap, then
+	  the original trap wasn't executed.
+01-11-26 +The value for 0 is now preceded by the base number when
+	  the base was not 10.
+01-11-26 +The default has compilation mode has been changes so that
+	  viraw mode will always be on.
+
+01-10-31  --- Release ksh93m  ---
+01-10-31  A for loop optimizer bug for subshells contained withing for
+	  loops has been fixed.
+01-10-16  typeset without arguments no longer outputs variable names
+	  that do not have any attributes that are set.
+01-10-16  A bug introduced in ksh93l in which assignments specified with
+	  the exec built-in were not being expanded properly has been
+	  fixed.
+01-10-11  An optimization bug in which ${!x) was treated as invariant in
+	  a for loop has been fixed.
+01-10-11  Unsigned integer variables in bases other than 10 are printed now
+	  expand in that base with the base prefix.
+01-10-10  A number of typos in the self generating man pages for shell
+	  built-ins have been fixed.
+01-10-04  The self generated man pages for hist and fc were not working
+	  correctly and have been fixed.
+01-10-03  Yet another optimizer bug in which shell patterns were
+	  treated as invariants has been fixed.
+01-09-27  Two bugs relating to multibyte history searches and to find
+	  have been fixed.
+01-09-27  A bug introduced in ksh93k in which the PATH searching was
+	  not restored after running a command with an assignment list 
+	  has been fixed.
+01-09-26  A bug in which a zero filled field was treated as octal when
+	  converted to integer has been fixed.
+01-09-26  Yet another bug in the optimization of for loops related to
+	  recursive functions with break or continue statements has been fixed.
+01-09-25 +The exponentiation operator ** was added to the shell arithmetic
+	  evaluation.  It has higher precedence than * and is left
+	  associative.
+01-09-25  The code was modified to use the ast multibyte macros
+	  and functions for handing multibyte locales.
+01-09-25 +The expansion ${parameter:offset:length} now handles negative
+	  offsets which cause offsets to be measured from the end.
+01-09-25  Some spelling errors in the documentation were corrected.
+01-09-24 +The /dev/tcp/host/port and /dev/udp/host/port now allow
+	  the ports to be specified by service name. 
+01-09-24 +The change staring with ksh93g in which the the appropriate
+	  library path variable is prepended with a corresponding library
+	  directory has been modified.  With the new method, only the
+	  library path defined in the file named .paths in the directory
+	  where the executable is found will be modified.  See the
+	  man page for more details.
+01-09-23 +The .fpath file (see ksh93h) is no longer looked for in each
+	  directory on the path to locate function directories.  The
+	  file named .paths is used instead.
+01-09-23  A bug in which IFS was not being restored after being changed in
+	  a subshell has been fixed.
+01-09-16 +With the vi and emacs edit modes, after a list of command
+	  or functions is generated with = or M-= respectively,
+	  any element from the list can be pasted on the command line
+	  by preceding the = or M-= with a numeric parameter specifying
+	  the position on the list.
+01-09-16  A bug in ksh93l caused command completion not to find aliases
+	  and functions.  Command listing from the edit mode was presented
+	  in reverse order.  This has been fixed.
+01-09-13  Another bug in the optimization of for loops related to subshells
+	  when traps were set has been fixed.
+01-09-07  A change in ksh93l caused brace expansion to stop working
+	  and this has been fixed.
+01-09-04  A bug introduced in ksh93k in which an arithmetic statement
+	  within a function that used name references did not follow the
+	  reference has been fixed.
+01-09-04  A bug introduced in ksh93l in which export -p did not prefix
+	  each export with the word export has been fixed.
+01-08-29  A bug in multibyte input which occurred when a partial multibyte
+	  character was received has been fixed.
+01-08-29  A bug introduced in ksh93l which could cause a core dump
+	  when an assignment list containing PATH is specified inside
+	  command substitution has been fixed.
+01-08-09  Another bug in the optimization of for loops in ksh93l caused
+	  errors in recursive functions using local variables that
+	  contained for loops has been fixed.
+01-07-27  A bug in which IFS would be unset after a command substitution
+	  inside a here document has been fixed.
+01-07-26  To conform to the POSIX standard, if you invoked ksh name,
+	  and name does not contain a /,  it will first try to run
+	  one in the current directory whether it is executable or not
+	  before doing a path search for an executable script.  Earlier
+	  versions first checked for an executable script using the
+	  PATH variable.
+01-07-23  A bug in which unset -f invoked in a subshell could unset a
+	  function defined in the parent has been fixed.
+01-07-16  A bug in the optimization of for loops in ksh93l caused
+	  name references to be treated as invariants has been fixed.
+01-07-09  A bug in which a discipline function applied to a local variable
+	  could cause a shell exception has been fixed.  Discipline
+	  functions can only be specified for global variables. 
+
+01-06-18  --- Release ksh93l  ---
+01-06-18  A bug in assigning integers larger than can be represented as
+	  long integers to floating point variables has been fixed.
+01-06-18  A bug in the handling of unsigned integers (typeset -ui) has
+	  been fixed.
+01-06-04  The evaluation of the PS1 prompt no longer effects the value
+	  of the $? variable.
+01-06-01  A small memory leak from subshells has been fixed.
+01-05-22  A bug in which attributes for variables that did not have
+	  values would be lost after a subshell has been fixed.
+01-05-22 +The %R format has been added to convert a shell pattern into
+	  an extended regular expression.
+01-05-22 +The escape sequences &#0092;, <JOIN>X, \C&#0091;.collating-element.&#0093;, and
+	  \x{hex} have been added to ASCII-C strings and to printf format
+	  strings.
+01-05-20 +Patterns of the form {n}(pattern) and {m,n}(pattern) are now
+	  recognized.  The first form matches exactly n of pattern whereas,
+	  the second form matches from m to n instances of pattern.
+01-05-20 +The shell allows *-(pattern), +-(pattern),  ?-(pattern),
+	  {m,n}-(pattern}, and @-(pattern) to cause the minimal
+	  match of pattern to be selected whenever possible rather
+	  than the maximal (greedy) match. 
+01-05-20 +The character class &#0091;:word:&#0093; has been added to patterns.
+	  The word class is the union of &#0091;:alnum:&#0093; and the character _.
+01-05-20 +Inside (...) pattern groups, the &nbsp;character is now treated
+	  specially even when in an enclosing character class.  The
+	  sequences, \w, \d, \s are equivalent to the character classes
+	  word, digit, and space respectively.  The sequences \W, \D,
+	  and \S are their complement sets. 
+01-05-20 +The shell now recognizes pattern groups of the form
+	  ~(options:pattern) where options or :pattern can be omitted.
+	  Options use the letters + and - to enable and disable options
+	  respectively.  The option letters g (greedy), i (ignore case)
+	  are used to cause maximal matching and to cause case
+	  insensitive matching respectively.  If :pattern is also
+	  specified, these options are only in effect while this
+	  pattern is being processed.  Otherwise, these options remain
+	  in effect until the end of the pattern group that they are contained
+	  in or until another ~(...) is encountered.  These pattern groups
+	  are not counted with respect to group numbering.
+01-05-14  When edit completion, expansion, or listing occurs in the
+	  middle of a quoted string, the leading quote is ignored when
+	  performing the completion, expansion, or listing.
+01-05-14  A small memory leak from subshells has been fixed.
+01-05-10  A bug in which open files were not restored after a subshell
+	  that had used exec to replace a file has been fixed. 
+01-05-10 +Redirection to a null file name now generates an error message. 
+01-05-09  The shell now rejects some invalid parameter substitutions that
+	  were previously processed in undefined ways.
+01-05-09  A bug in which the output of select was not flushed before the
+	  read when input did not come from the terminal has been fixed. 
+01-05-08  A bug in which job ids would not be freed for interactive shells
+	  when subshells ran built-ins in the background has been fixed.
+01-05-08 +The FPATH variable now requires an explicit . to cause the
+	  current directory to be treated as a function directory. 
+01-05-08  A bug in read -n when echo mode was disabled has been fixed.
+01-05-07  A bug in which function definitions could be listed as part
+	  of the history has been fixed.
+01-04-30 +This release uses a new and often much faster pattern matcher than
+	  earlier releases.
+01-04-30 +An optimizer now eliminates invariant parameter expansions from
+	  for while and until loops.
+01-04-30 +The variable .sh.match is set after each pattern match (# % or /)
+	  in a variable substitution.  The variable .sh.match is an
+	  indexed array with element 0 being the complete match. 
+	  The array is only valid until the next subsequent pattern
+	  match or until the value of the variable changes which ever
+	  comes first.
+01-04-30 +A self generating man page has been added to shcomp.  Also,
+	  shcomp now stops compiling when it finds an exit or exec
+	  command and copies the remainder so that it can be used
+	  for standard input.
+01-04-30 +The shcomp command was modified so that it can work in an
+	  EBCIDIC environment and that binary scripts are portable
+	  across environments.
+01-04-30  A bug in the handling of a trailing : in PATH has been fixed.
+01-04-30  A bug in which the builtin version of a command would get invoked
+	  even though the full pathname for the command was specified
+	  has been fixed.
+01-04-30  A bug in which read would loose the last character when
+	  reading the last line of a file that did not contain a new-line
+	  character has been fixed.
+01-04-23  A bug on some systems in which in vi mode the end of file
+	  character and end of line character could be swapped has
+	  been fixed.
+01-04-23  A bug on some systems in which invoking a shell script that
+	  did not have execute permission could set the exit value to
+	  127 rather than 126 has been fixed.
+01-04-20  A bug in which read -n from a pipe would block if fewer than
+	  n characters was received has been fixed.
+01-04-09  A bug in which invalid patterns, for example, ) by itself,
+	  was not treated as a string has been fixed so that if i=')',
+	  then &#0091;&#0091; $i == $i &#0093;&#0093; is true.
+01-04-09 +The shell arithmetic now interprets C character constants.
+01-04-09  A bug in which a non-zero return from a function defined
+	  with the function reserved word did not trigger the ERR
+	  trap or exit with set -e has been fixed.
+01-04-02  A bug on some systems, in which characters above 127 were
+	  not displayed correctly in vi or emacs edit mode has been fixed.
+01-04-02  A bug on some systems, introduced in the 'k' point release, in
+	  which the erase character in viraw mode was moving the cursor
+	  to the left without erasing the character has been fixed.
+01-04-02  On some systems the wcwith() function was returning a wrong
+	  value for characters and caused characters to be displayed
+	  incorrectly from the shell edit modes.  A work around for
+	  this problem has been added. 
+01-03-26  A bug in which valid scripts could produce syntax errors
+	  when run with locales that considered characters such as "'"
+	  to be space characters has been fixed.
+01-03-20  A bug in which an syntax error in an arithmetic expression
+	  entered interactively could cause the shell to go into
+	  an infinite loop outputting the error message has been fixed.
+01-03-10 +ksh93 accepts -l as a synonym for -L in test on systems for
+	  which /bin/test -l tests for symbolic links.
+01-03-10  A bug in parsing scripts in which { and } are used in place of
+	  in and esac in case statements embedded in compound commands
+	  has been fixed.  Use of { and } for in and esac is obsolete.
+01-03-06  A bug in which an argument of the form foo=bar was not
+	  being passed correctly to a traced function whose name
+	  was foo has been fixed.
+01-03-02  Using $(trap -p name) did not print the name of the current
+	  trap setting for trap name.
+01-02-26  Exported floating point variables gave incorrect results
+	  when passing them to ksh88.  This has been fixed.
+01-02-25  A race condition in which a coprocess which completed too quickly
+	  would not allow subsequent coprocesses to start has been fixed.
+01-02-25  The 'g' format specifier is now handled by printf.  It had
+	  inadvertently been omitted.
+01-02-20  The + was not being displayed during an execution trace
+	  with the += assignment operator.
+01-02-19  The error message which occurs when the interpreter name
+	  defined on the #! line does not exist is more informative.
+01-02-19  A bug in which $0 would not be set correctly when a
+	  script with #! was invoked by full pathname from the
+	  directory of the script has been fixed.
+01-02-19  A shell script did not always pick up tty mode changes
+	  made by external commands such as stty which could
+	  effect the behavior of read.
+01-02-19  The -u, -g, and -k unary tests did not give the correct
+	  results when used with negation and this has been fixed.
+
+01-02-05  --- Release ksh93k+  ---
+01-02-05  The sequence \&lt;newline&gt; inside $'...' was not incrementing
+	  the line count and this has been fixed.
+01-02-05 +Modified expansion of "${@-}" so that if no arguments are set
+	  it results in null string rather than nothing.
+01-02-02  memory leak problem with local variables in functions fixed.
+01-01-25 +allow arithmetic expressions with float%int and treat them
+	  as ((int)float)%int rather than as an error. 
+01-01-19  read -n1 was not working and has been fixed.
+01-01-17 +ksh now handles the case in which a here document in command
+	  substitution $() is terminated by the trailing ).  Previously,
+	  a new-line was needed at the end of the delimiter word. 
+01-01-02  A bug in which a KEYBD trap would cause a multi-line token
+	  to be processed incorrectly has been fixed.
+00-12-10 +Arithmetic integer constants can now have L and U suffices. 
+00-12-10  A bug in the processing of arithmetic expressions with compound
+	  variables when the -n option is on has been fixed.
+00-12-08  A bug in M-f and M-b from emacs mode has been fixed.  This
+	  bug only occurs when ksh93 is compiled without MULTIBYTE enabled.
+00-11-29  A bug in which jobs -p would yield 0 for background
+	  jobs run in a script has been fixed.
+00-11-21  A bug in integer arrays in which the number of elements is
+	  incorrect when the ++ operator is applied to a non-existing
+	  element has been fixed.  For example, integer x; ((x&#0091;3&#0093;++)).
+00-11-20  A timing bug in which the shell could reset the terminal
+	  group to the wrong value in the case that the a new process
+	  changes the terminal group during startup has been fixed.
+
+00-10-27  --- Release ksh93k  ---
+00-10-27  Using tab for completion now works only when applied
+	  after a non-blank character at the end of the current line.
+	  In other case a tab is inserted.
+00-10-27  A bug in the emacs edit mode for ^X^E has been fixed.
+	  The ^X^E sequence is supposed to invoke the full editor
+	  on the current command.
+00-10-18  A bug in which expansions of the form ${var//pattern/string}
+	  did not work correctly when pattern was '/' or "/" has
+	  been fixed.
+00-10-18 +The output format for indexed arrays in compound variables
+	  has been modified so that it can be used as input.
+00-10-18  Assignments with name references (typeset -n) will now
+	  implicitly unreference an existing name reference.
+00-10-17  A bug the += append operator when a single array element
+	  is appended to a variable that is not an array has been fixed.
+00-10-16  A bug in which the SIGCONT signal was being sent to
+	  each process will kill -0 or kill -n 0 has been fixed.
+00-10-12 +The arithmetic evaluation portion has been rewritten to
+	  perform a number of optimizations.
+00-10-10  A bug in which name prefix matching ${!name.*} was not
+	  checking name to see if it was a name reference has been fixed.
+00-09-26  A bug in the multibyte version in which the width of for
+	  non-printing characters was not correct has been fixed.
+00-09-12 +Made changes to get multibyte editing work on UWIN for windows
+00-09-12  A bug in which multibyte characters would be displayed incorrectly
+	  has been fixed.
+00-08-08  Removed build dependency on iswprint() and iswalph().
+00-07-20  In some cases the read builtin would read more than a single
+	  line from a pipe on standard input and therefore leave the seek
+	  position in the wrong location.
+00-07-05 +If the directory / is on the path, a / will not be inserted
+	  between the directory and the file name during path searching
+	  to avoid searching // for systems that treat this specially.
+00-06-26  A bug in which on rare occasions wait could return before all
+	  jobs have completed has been fixed.
+00-06-21  A bug in which backspace did not work correctly during the
+	  R replace directive in vi-mode has been fixed.
+00-06-12 +Added variable name completion/expansion/listing  to the set of
+	  completions.  Variable name completions begin with $ or "$ followed
+	  by a letter. 
+00-05-09  --- Release ksh93j  ---
+00-05-09  Modified command substitution to avoid using /tmp files when
+          run on read-only file systems. 
+00-04-17 +Modified printf to handle '%..Xc' and '%..Xs' options where X
+	  is not an alpha character.  Previous versions core dumped with this.
+00-04-10 +Changes to multibyte editing code were made to use standard
+	  ISO C functions rather than methods devised before the standard.
+00-04-09  Add %H options to printf to output strings with &lt;"'&amp;\t&gt; properly
+	  converted for use in HTML and XML documents.
+00-04-07 +Modified getopts builtin to handle <.>..</.>< >in usage string</ >
+	  by invoking specified function.
+00-04-04  Added self generating man pages for bg, fc, fg, disown, jobs,
+	  hist, let, ., and ulimit.
+00-03-30 +The append operator += has been added and can be used
+	  for all assignments, strings, arrays, and compound variables.
+00-03-30 +Code was modified in several places to support automatic
+	  generation of C locale dictionaries.
+00-03-28  A bug in which the set and trap commands invoked with --name
+	  type arguments would terminate the invoking script  has
+	  been fixed.
+00-03-27  A bug in which the library path variable was not updated  
+	  correctly on some systems as described in the 'g' point
+	  release has been fixed. 
+00-03-07  printf now returns a non-zero exit status when one of
+          its arguments cannot be converted to the given type. 
+00-03-05  The return value and error message for a command that
+          was found on the path but was not executable was set
+          incorrectly.
+00-03-05  A prototype for ioctl() was removed from the vi edit mode.
+
+00-01-28  --- Release ksh93i  ---
+00-01-28 +Most of the built-in commands and ksh itself are now
+          self documenting.  Running command --man will produce
+          screen output.  Running command --html produces the
+          man page in html format.
+00-01-28 +The getopts builtin can process command description
+          strings to produce man pages.
+00-01-28  A bug in which a script could terminate when getopts
+          encountered an error when invoked inside a function
+          has been fixed.
+00-01-28  When a symbolic link was specified as the name of
+          the script to invoke by name, the value of $0 was
+          set to the real file name rather than the link name
+          in some cases and this has been fixed.
+00-01-28  A bug in which the precision given as an argument
+	  to printf was not working has been fixed.
+
+99-03-31  --- Release ksh93h  ---
+99-03-31 +The PATH search algorithm has been modified to look

+ast-ksh :PACKAGE: ksh93 libast libcmd libcoshell libsum libdll
+
+:COVERS: ksh
+
+:LICENSE: *.open
+
+:CATEGORY: shells
+
+:INDEX: ksh and support libraries
+
+:DESCRIPTION:
+	The AT&T Software Technology ast-ksh package from AT&T Research
+	contains ksh and support libraries. This is the minimal set of
+	components needed to build ksh.
+
+:DETAILS: cyg
+	:README:
+		This package installs a standalone ksh93 executable ksh93.exe
+		and its man page ksh93.1.  If /bin/ksh.exe does not exist then
+		these symlinks
+			/bin/ksh.exe => ksh93.exe
+			/usr/share/man/man1/ksh93.1 => ksh.1
+		are created.  This allows alternative ksh impelementations,
+		e.g., /bin/pdksh.exe, to be selected by changing the ksh.exe
+		and ksh.1 symbolic links.  In addition, ksh and ksh93 paths are
+		added to /etc/shells if not already present.
+		$()
+		Each builtin or special command accepts the --man and --html
+		options to list the man page on the standard error. The --???
+		option describes the self documenting options available to all
+		builtin and special commands.
+		$()
+		The stanadlone ksh is statically linked with the ast libcmd
+		library which provides several builtin versions of /bin
+		commands. "builtin | grep /opt/ast/bin" lists the libcmd
+		builtins on the standard output. /opt/ast/bin/FOO accesses
+		the FOO builtin, whether the /opt/ast/bin directory exists
+		or not. "builtin FOO" allows /opt/ast/bin/FOO to be accessed
+		as FOO, bypassing the $PATH setting. To enable all libcmd
+		builtins do one of the following:
+		  (a) create the directory /opt/ast/bin and the file
+		      /opt/ast/bin/.paths with this line
+		      	BUILTIN_LIB=.
+		      and place /opt/ast/bin before /bin and /usr/bin in $PATH
+		      (this will affect all ksh subshells and scripts)
+		  (b) run "builtin $( builtin | sed -e '/\//!d' -e 's,.*/,,' )"
+		      (this will affect only the current shell)
+		Some scripts may run significantly faster with libcmd builtins
+		enabled.
+		$()
+		The ast library checks the DOSPATHVARS environment variable
+		for variable path values to convert to and from native windows
+		format when cross-executing between cygwin and non-cygwin
+		programs. The value is a space separated list of environment
+		variables to convert. PATH is handled by cygwin so it is not
+		converted by the ast library.
+		$()
+		The astksh cygwin source package provides a bootstrap build
+		environment that is not suited for an edit/build/debug cycle.
+		If you want to explore and modify the source then you should
+		install the (non-cygwinized) ast-base package which includes
+		AT&T nmake. With ast-base you will also be able to regenerate
+		the astksh cygwin source and binary packages.
+		$()
+		For more information on ksh and other AT&T ast tools see
+		   http://www.research.att.com/sw/download/

+		package write cyg base source version=$(version.original) $(name.original)
+		package write cyg base binary version=$(version.original) $(name.original)
+	$()
+	using the $(org)-base package. To download and install the latest
+	$(org)-base source package in /opt/$(org) run:
+	$()
+		PATH=/opt/$(org)/bin:$PATH
+		cd /opt/$(org)
+		package authorize "NAME" password "PASSWORD" setup flat source $("\\")

+	$()
+	and export /opt/$(org)/bin in PATH to use. The NAME and PASSWORD signify your
+	agreement to the software license(s). All users get the same NAME and PASSWORD.
+	See $(url) for details. If multiple architectures may be built under
+	/opt/$(org) then drop "flat" and export /opt/$(org)/arch/`package`/bin in PATH
+	to use. To update previously downloaded packages from the same url simply run:
+	$()
+		cd /opt/$(org)
+		package setup
+		package make
+	$()
+	To download and install the latest $(org)-base binary package in
+	/opt/$(org) change "source" to "binary" and omit "package make".
