=== SMP Support ===
The major news is the support for SMP (Symmetric MultiProcessing).
SMP is supported by most modern operating systems like Linux, Windows, Mac OSx,
Solaris and is becoming more important now when dual processors,
hyper-threading technology and multi-core systems are a reality.
With Erlang, most of the problems which occur in multi-threaded programs have
been solved once and for all in the Erlang VM and do not have to be handled by
the application programmers.
In the SMP version of the Erlang virtual machine, there can be many process
schedulers running in separate OS threads. As default there will be as many
schedulers as there are processors or processor cores on the system.
The SMP support is totally transparent for the Erlang programs. That is, there
is no need to change or recompile existing programs. Programs with built-in
assumptions about sequential execution must be rewritten in order to take
advantage of the SMP support, however.
In this release, the Erlang VM supports SMP with focus on stability. There will
follow a number of subsequent steps with necessary optimizations and support
for more platforms.
=== Erlang Language and Related Issues ===
* The andalso and orelse operators are now allowed to be used in guards.
That also applies to match specifications.
* The BIF is_record/3 can now be used in guards. Also, is_record/3 can now
be called without an erlang: module prefix for consistency with the other
is_* functions.
* The compiler options ignore_try and ignore_cond, which allowed code that
used unquoted try or cond as atoms or record tags, has been removed. Old
code that depended on the options need to be revised to have occurrences
of try or cond as atom or record tags single-quoted. (Note: Although cond
is a reserved keyword, there is no cond statement. It might be introduced
in a future release.)
* (ERTS 5.4.8) The new fun M:F/A construct creates a fun that refers to the
latest version of M:F/A. This syntax is meant to replace tuple funs {M,F}
which have many problems.
* (ERTS 5.4.8) The new type test is_function(Fun, Arity) -- which may be
used in guards -- test whether Fun is a fun that can be applied to Arity
arguments.
=== New Applications ===
Dialyzer
Dialyzer is a static analysis tool that identifies software discrepancies such
as type errors, unreachable code, unnecessary tests, etc in single Erlang
modules or entire (sets of) applications.
Inviso
The Inviso application, together with some new extensions to Runtime_Tools, is
aimed at providing features for efficient tracing of production Erlang/OTP
systems:
* Distributed tracing - tracing on any number of Erlang nodes.
* Autostart - tracing during system start-up.
* Overload protection - mechanisms for suspending and later reactivating
tracing, should an overload situation occur.
* Enhanced use of meta tracing.
* Trace cases - predefined specifications of what to trace.
* Off-line merging and formatting of log files.
Inviso is still under development. An easier-to-use trace tool, using the
features listed above, is planned to be released as an R11B patch in Q3/Q4
2006.
SSH
The SSH application is an Erlang implementation of the secure shell protocol.
It is considered to be a beta release, meaning there can be changes made to the
API before it reaches 1.0.
=== Existing Applications ===
Compiler
(Compiler 4.3.6) It is now possible to encrypt the debug information in Beam
files.
Debugger
(Debugger 2.0) The debugger can now handle the try/catch language construct.
Inets
The Erlang implementation of the TFTP procotcol, tftp, is now documented.
Kernel
In Kernel 2.10.X, several bug fixes and improvements have been made in global ,
the global name registration facility.
OS_Mon
(OS_Mon 2.0) The entire OS_Mon application (code and documentation) has been
reviewed and consequently updated with the goal to make the application more
robust, homogeneous and easier to configure.
STDLIB
Added the zip module with functions for reading and creating zip archives.

- November 2002
Feature highlights of this new release are:
* Much improved FFI support (contributed by Alastair Reid), bringing Hugs
really very close to the Haskell FFI specification.
* Adoption of a significant subset of GHC's hierarchical libraries
(contributed by Ross Paterson).
* An (allegedly) complete implementation of the Haskell98 module system
(Sigbjorn Finne).
* Numerous bug fixes since the previous major release in Dec 2001.
- November 2003
There has been substantial internal restructuring. In addition to numerous
bug fixes, user-visible changes include:
* The beginnings of a User's Guide (though still incomplete).
* The Double type is now double-precision on most architectures.
* Hugs now relies on the same hierarchical libraries as GHC and Nhc98, and
provides almost all of them. For now, compatibility with the old libraries
is provided by stub modules, but users are encouraged to migrate to the
new libraries.
* Full support for imprecise exceptions (but not asynchronous ones). Most
runtime errors are now reported by applying print to an Exception
(formerly the built-in printer was applied to the faulty redex).
* Integrated .NET support (on Windows platforms).
* The -e, -f, -i, -N, -W and -X options and the :project command have been
removed.
* A searchpath may include an entry of the form "directory/*", meaning all
the immediate subdirectories of directory (see -Pstr).
- March 2005
This release is primarily targeted at Unix systems to gain experience with
new features. The new Cabal-based library build system has the potential to
make building on Windows easier, but it's not there yet. Volunteers welcome.
In addition to numerous bug fixes, user-visible changes include:
* The default current module is now the empty module Hugs.Base instead of
the Prelude (see Section 2.2).
* The Char type and the Char module now support Unicode as specified in the
Haskell 98 Report (contributed by Dmitry Golubovsky). Character oriented
I/O uses a byte encoding of characters determined by the current locale
(see Section 3.3).
* The new -X option can be used to group several options into one argument.
This is now needed for executable runhugs scripts (using the Unix "#!"
feature) that require two or more options (see Section 4.1).
* The syntax of the ffihugs command has changed (see Section 4.2). The +G
and +L options are gone, and a new -i option can be used to specify
include files.
* Hugs now has basic support for the Cabal packaging system (see Section 3.4).
- May 2006
* The default current module is now the empty module Hugs (see Section 2.2).
* The compatibility libraries are no longer included on the default search
path. You can access them by adding "{Hugs}/oldlib" to the search path
(see -Pstr), but they will be removed in the next release.
* Rewritten graphical Windows interface (contributed by Neil Mitchell; see
Section 4.3).
* New :main command (contributed by Neil Mitchell).

=================
User visible changes
--------------------
* SAVEINITMEM now accepts :SCRIPT argument that disables interpreting
the first positional argument as the script name; and :DOCUMENTATION
argument that is printed by the new -help-image command line option.
See <http://clisp.cons.org/impnotes/image.html> and
<http://clisp.cons.org/impnotes/clisp.html#opt-help-image> for details.
* FFI:UINT64 and FFI:SINT64 are now compatible with C's long long type.
* Stack overflow detection and recovery finally work fine on Unix.
Libsigsegv is required for this, on all platforms (including MS-Windows).
CLISP should neither exit nor crash under infinite recursion.
If your distribution has CLISP compiled without libsigsegv, report
the missing feature to its maintainer.
Note that libsigsegv 2.4 is required, there are bugs in libsigsegv 2.3!
* It is now possible to specify the default method-combination of a generic
function, to be used when the DEFGENERIC form does not specify the
:METHOD-COMBINATION explicitly, through a default initarg specification
for the :METHOD-COMBINATION keyword on the generic function class.
* Readline completion works with non 1:1 terminal encodings, e.g. UTF-8.
* WITH-KEYBOARD works with a Unix tty even when SLIME hijacks *TERMINAL-IO*.
* I/O operations on Win32 are now much faster.
* New functions: POSIX:FFS, POSIX:PATHCONF.
* Infrastructure:
+ Top-level configure now accepts a new option --with-gmalloc to use the
GNU malloc implementation instead of the one supplied by libc.
You may need it on older HP-UX and newer OpenBSD systems.
See file unix/PLATFORMS for more information.
+ The value of the environment variable CFLAGS is respected by configure.
* Bug fixes:
+ SOCKET:SOCKET-SERVER :INTERFACE now behaves as documented.
+ EXT:READ-BYTE-NO-HANG and SOCKET:SOCKET-STATUS used to hang on
buffered binary sockets.
+ Allow DESTRUCTURING-BIND (a . b) with circular and dotted lists.
+ ADJUST-ARRAY of zero length adjustable string now works.
+ TIME now reports correct results when the heap grows over 4GB.
+ RAWSOCK functions now handle :START/:END arguments correctly.
+ BDB:DBC-GET now accepts :READ-COMMITTED and :READ-UNCOMMITTED.
+ POSIX:GROUP-INFO and POSIX:USER-INFO now handle errors correctly.
* Portability:
+ Support DragonFly BSD.

Changes since Guile 1.6.7 (changes in 1.6.8):
* Changes to the distribution
** A number of GCC 4.0 related build problems have been fixed.
A number of changes have been made to accomodate GCC 4.0.
* Changes to the stand-alone interpreter
** `readline-set!' now works.
* Changes to Scheme functions and syntax
** Guile now allows multiple line comments to end without a trailing newline.
Previously Guile would throw an exception if a multiple line comment
ended without a trailing newline. Now "!#" will end a multiple line
comment regardless of what follows.
** Guile supports newer versions of SLIB more cleanly.
Guile now relies on the upstream SLIB code (guile.init) to handle the
load process. Previously Guile relied on its own copy of that code,
which was incorrect, at least for more recent versions of SLIB.
If you still need to use Guile with an older version of SLIB, and the
new approach doesn't work for you, please add the following definition
to your code before (ice-9 slib) is loaded for the first time:
(define *guile-use-old-ice-9-slib* #t)
This will cause Guile to revert to the old load behavior.
** The r5rs numerator and denominator functions have been added.
These are now available in the default environment.
** `/' fix to <any>/0-<y>i complex division case, avoiding divide-by-zero
** `array-map!' fix, accepts just a destination array again
** `cons*', `list' fix to not clobber source list when called via `apply'
** `string-index', `split-string' and other string func fixes for 8-bit chars
** `number->string' fix for parsing of polar complex number with invalid angle
** (ice-9 poe) bug fixes
** srfi-1 `lset-adjoin' fix to actually use given equality procedure
** srfi-1 `lset-union' fixes to operate in the way specified by the SRFI
Note in particular that if the first list is empty then the first
non-empty is the starting point, and duplicates are not cast out of
that. So
(lset-union = '() '(1 1 1)) => '(1 1 1)
where previously it was '(1). This, though perhaps unhelpful, comes
from the SRFI spec (that if list A is empty then the result is B).
** srfi-1 `lset=', `list=' fix to equality procedure argument order
** srfi-17 avoid deprecation warnings about reexport
** srfi-19 new 2005 leap second
** srfi-39 new parameter versions of `current-output-port' etc, per SRFI
** make-stack can now correctly construct a stack from a continuation.
** Output string port speed problems have been improved
Output string port (open-output-string, etc) writing was very slow at
about 50 to 100 kbytes or above. This affected various things, in
particular regexp-substitute/global on a large string, and stack
backtraces with a large object.
** Bug fix: printing values no longer protects them from GC
A bug in the printing code used to mean that printing a value (using
`display' or `write') would incorrectly protect that value from GC for
a while afterwards. This has now been fixed.
* Changes to the C interface

and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.
For example, "make show-buildlink3" in fonts/Xft2 displays:
zlib
fontconfig
iconv
zlib
freetype2
expat
