Tested on FreeBSD, known not to work on NetBSD/i386.
News
changes in sbcl-1.0.35 relative to sbcl-1.0.34:
* optimization: ROUND with a single single-float or double-float argument
is properly inlined when possible.
* optimization: Slightly better code is generated for integer<->float
conversions and for single-float<->double-float conversions on x86-64.
* optimization: SB-ROTATE-BYTE:ROTATE-BYTE now generates more efficient
code for 32-bit and 64-bit rotations on x86-64.
* bug fix: The install script changes the ownership of directories as well
as files for contrib modules using asdf. (thanks to Eugene Ossintsev;
launchpad bug lp#508485)
* bug fix: TRUNCATE with a single single-float or double-float argument is
properly inlined when possible. (launchpad bug lp#489388)
* bug fix: Passing a rotation count of zero to SB-ROTATE-BYTE:ROTATE-BYTE
no longer causes a compiler error on x86 and ppc.
* bug fix: GET-MACRO-CHARACTER bogusly computed its second return value
always relative to *READTABLE* rather than the passed argument.
changes in sbcl-1.0.34 relative to sbcl-1.0.33:
* minor incompatible change: threading support is now enabled by default
on x86[-64] Linux.
* enhancement: SB-INTROSPECT:DEFTYPE-LAMBDA-LIST now also works on most
builtin types.
* enhancement: Errors during compile-time-too processing (i.e. EVAL-WHEN)
are now caught and reported just like errors during macroexpansion.
* enhancement: SB-POSIX now provides access to tcdrain(), tcflow(),
tcflush(), tcgetsid(), and tcsendbreak(). (thanks to Jerry James)
* enhancement: ASDF systems can now depends on SB-QUEUE.
* fixes and improvements related to Unicode and external formats:
** bug fix: error handling and restart usage in the ucs-2 external format
has been improved.
** there is now an implementation of the ucs-4 external format.
** the utf-16 and utf-32 external formats are supported.
* bug fix: SB-POSIX wrapper for putenv no longer tries to put lisp strings
in the environment. setenv() and unsetenv() are also provided. (reported by
Fare Rideau; launchpad bug lp#460455)
* bug fix: LOAD of both .fasl and .FASL type files now forces fasl-style
loading. This ensures sensible errors for .FASL files from other
implementations on case-insensitive filesystems. (reported by Willem
Broekema; launchpad bug lp#489417)
* bug fix: #p"\\\\" can now be read without error on Win32. (reported by
Willem Broekema; launchpad bug lp#489698).
* bug fix: some minor code rearrangements to reenable warning-free building
from CMUCL (reported by xme@gmx.net; launchpad bug lp#491104)
* bug fix: PRINT-OBJECT for clos instances respects the right margin when
pretty printing
* bug fix: FIND-PACKAGE & DEFPACKAGE were not thread safe. (reported by
Attila Lendvai)
changes in sbcl-1.0.33 relative to sbcl-1.0.32:
* new port: support added for x86-64 NetBSD. (thanks to Aymeric Vincent)
* improvement: support O_LARGEFILE access to files larger than 2GB on
x86-64/linux. (thanks to Daniel Janus; launchpad bug lp#453080)
* new feature: SB-INTROSPECT:WHO-SPECIALIZES-DIRECTLY to get a list of
definitions for methods specializing on the passed class itself.
* new feature: SB-INTROSPECT:WHO-SPECIALIZES-GENERALLY to get a list of
definitions for methods specializing on the passed class itself, or on
subclasses of it.
* new build flag: :sb-xref-for-internals; SBCL will collect xref information
about itself during the build (e.g. for M-? in Slime), if this flag is
enabled in customize-target-features.lisp. This will increase the core
size by about 5-6mb, though, so it's mostly interesting to SBCL
developers.
* new feature: various GENCGC tuning parameters have been experimentally
documented and exported from SB-EXT. See documentation for details.
* fixes and improvements related to Unicode and external formats:
** the Unicode character database has been upgraded to the
Unicode 5.2 standard, giving names and properties to a number of new
characters, and providing a few extra characters with case
transformations.
** improvement: restarts for providing replacement input/output on coding
errors for fd-stream external formats.
** improvement: where :<encoding> is a keyword corresponding to an
external format the system supports, it is now possible to specify
(:<encoding> :replacement <character>) as an external format which will
automatically substitute <character> on encoding or decoding errors for
streams and for STRING-TO-OCTETS and its inverse. (launchpad bug
lp#317072)
** improvement: the file streams underlying the standard streams (such as
*STANDARD-INPUT*, *TERMINAL-IO*) are opened with an external format
which uses the replacement mechanism to handle encoding errors,
preventing various infinite error chains and unrecoverable I/O
confusion.
** minor incompatible change: the utf-8 external format now correctly
refuses to encode Lisp characters in the surrogate range (char-codes
between #xd800 and #xdfff).
** fix a typo preventing conversion of strings into octet vectors
in the latin-2 encoding. (reported by Attila Lendvai; launchpad bug
lp#471689)
** fix a bug in the octet multibyte handling of decoding errors and the
USE-VALUE restart. (launchpad bug lp#314939)
** fix the bug underlying the expected failure in the FORCE-END-OF-FILE
restart on fd-stream decoding errors.
** fix a bug in the ATTEMPT-RESYNC fd-stream decoding restart when the
error is near the end of file.
** fix a double-error case in unibyte octet conversions, when the first
use of USE-VALUE is ignored.
** fix bugs in handling of undefined code points in unibyte encodings.
** fix LISTEN (and consequent hangs in READ-CHAR-NO-HANG) on bivalent
streams after an UNREAD-CHAR.
* enhancement: SB-INTROSPECT:ALLOCATION-INFORMATION also reports if the
object is allocated in a boxed region of dynamic space.
* enhancement: SB-POSIX:FORK now signals an error if an attempt to
fork with multiple Lisp threads running is made, instead of going
ahead with unpredictable consequences. (reported by Leslie Polzer)
* bug fix: uses of slot accessors on specialized method parameters within
the bodies of SLOT-VALUE-USING-CLASS methods no longer triggers a type
error while finalizing the class. This fix may cause classes with slot
accessors to be finalized later than previously. (reported by Lars Rune
Nøstdal; launchpad bug lp#473699)
* bug fix: restore buildability on the MIPS platform. (regression from
1.0.30.38, reported by Samium Gromoff)
* bug fix: inspecting closures is less likely to fail with a type error.
* bug fix: no timer starvation when setting the system clock back.
(launchpad bug lp#460283)
* bug fix: WITH-STANDARD-IO-SYNTAX now binds *PRINT-PPRINT-DISPATCH* to the
standard pprint dispatch table as specified by CLHS.
* bug fix: give CLISP a hint about a type declaration to enable it to build
the cross-compiler without warnings. (thanks to Josh Elasser; launchpad
bug lp#396597)
* bug fix: correctly dump literal objects in defaulting forms of arglists.
(reported by Attila Lendvai; launchpad bug lp#310132)
* bug fix: distinguish in type specifiers between arrays that might be
complex and arrays that are definitely complex. (launchpad bug lp#309129)
* bug fix: SUBTYPEP knows that the SYMBOL type is not SUBTYPEP the KEYWORD
type. (reported by Levente Mészáros; launchpad bug lp#485972)
* bug fix: setting the value of a symbol-macro within a method in the
presence of type declarations works properly again. (reported by Iban
Hatchondo; launchpad bug lp#485019)
changes in sbcl-1.0.32 relative to sbcl-1.0.31:
* optimization: faster FIND and POSITION on strings of unknown element type
in high SPEED policies. (thanks to Karol Swietlicki)
* optimization: faster CONCATENATE 'STRING in low SPEED policies (reported
by David Vázquez)
* improvement: better error signalling for bogus parameter specializer names
in DEFMETHOD forms (reported by Pluijzer)
* bug fix: DELETE-FILE once again works on logical pathnames (regression
since 1.0.30.49)
* bug fix: LOGICAL-PATHNAME signals a TYPE-ERROR if pathspec is specified
incorrectly.
* bug fix: redefinition of a class via DEFCLASS without :DEFAULT-INITARGS
removes previous default initargs (reported by Lars Rune Nøstdal and
Samium Gromoff)
* bug fix: correct WHO-CALLS information for inlined lambdas with complex
lambda-lists. (reported by Peter Seibel)
* bug fix: SAVE-LISP-AND-DIE option :SAVE-RUNTIME-OPTIONS did not work
correctly when starting from an executable core without saved runtime
options (reported by Faré Rideau, thanks to Zach Beane)
* bug fix: (SETF SLOT-VALUE) signalled a warning which should have been
an optimization note instead. (reported by Martin Cracauer)
* bug fix: WITH-SLOTS did not work with THE forms. (thanks to David Tolpin)
* bug fix: Have RUN-PROGRAM with :INPUT T only run the subprocess in a
new process group if it doesn't need to share stdin with the sbcl
process. (thanks to Leslie Polzer)
* bug fix: SATISFIES could be misoptimized to refer to a local function.
(reported by Stanislaw Halik)
changes in sbcl-1.0.31 relative to sbcl-1.0.30:
* improvement: stack allocation is should now be possible in all nested
inlining cases: failure to stack allocate when equivalent code is manually
open coded is now considered a bug.
* improvements related to Unicode:
** the Unicode character database has been upgraded to the
Unicode 5.1 standard, giving names and properties to a number of new
characters, and providing a few extra characters with case
transformations.
** the system now recognizes and produces names for Unicode Hangul
syllable characters.
** the EBCDIC-US external-format is now supported for octet operations
(as well as for stream operations).
* new feature: experimental :EMIT-CFASL parameter to COMPILE-FILE can
be used to output toplevel compile-time effects into a separate .CFASL
file.
* optimization: COERCE to VECTOR, STRING, SIMPLE-STRING and recognizable
one-dimenstional subtypes of ARRAY is upto 70% faster when the coercion is
actually needed.
* optimization: TRUNCATE on known single- and double-floats is upto 25%
faster.
* optimization: division of floating point numbers by constants uses
multiplication by reciprocal when an exact reciprocal exists.
* optimization: multiplication of single- and double-floats floats by
constant two has been optimized.
* optimization: ARRAY-IN-BOUNDS-P is resolved at compile-time when
sufficient type information is available. (thanks to Leslie Polzer)
* optimization: SLOT-VALUE and (SETF SLOT-VALUE) with constant slot names on
known structure objects are as efficient as defstruct generated accessors.
* optimization: unused vector creation can now be optimized away.
* improvement: ASDF systems can now depends on SB-INTROSPECT.
* improvement: a STYLE-WARNING is signalled when a generic function
clobbers an earlier FTYPE proclamation.
* improvement: the compiler is able to track the effective type of
generic function across method addition and removal even in the
absence of an explicit DEFGENERIC.
* improvement: DESCRIBE now reports on symbols naming undefined
but assumed or declared function as well.
* improvement: recompilation of systems using SB-GROVEL now works
(thanks to Leslie Polzer)
* improvements to SB-CLTL2 (thanks to Larry D'Anna):
** functions DECLARATION-INFORMATION, PARSE-MACRO, and ENCLOSE have been
documented.
** AUGMENT-ENVIRONMENT and DEFINE-DECLARATION have been implemented.
** DECLARATION-INFORMATION now supports declaration name DECLARATION as
well as user defined declaration names.
** VARIABLE-INFORMATION is now aware of alien variables.
* improvement: improved address space layout on OpenBSD (thanks to Josh
Elsasser)
* improvement: pretty-printing of various Lisp forms has been improved
(thanks to Tobias Rittweiler)
* bug fix: calls to DECODE-FLOAT and INTEGER-DECODE-FLOAT whose value was
unused were deleted in safe code. (reported by John Fremlin)

Stelian Ionescu)
* bug fix: a failing AVER in CONVERT-MV-CALL has been fixed. (thanks to
Larry D'Anna)
* bug fix: a failing AVER in %ALLOCATE-CLOSURES conversion has been fixed
(thanks to Larry D'Anna)
* bug fix: SLEEP supports times over 100 million seconds on long on OpenBSD
as well. (reported by Josh Elsasser)
* bug fix: DELETE-FILE on streams no longer closes the stream with :ABORT T,
leading to possible attempts to delete the same file twice. See docstring
on DELETE-FILE for details. (reported by John Fremlin)
* bug fix: DELETE-FILE once again deletes the file named by the pathname
designator argument, rather than its truename. (reported by Luis
Oliveira)
* bug fix: the low-level debugger had 32-bit assumptions and was missing
information about some array types. (thanks to Luis Oliveira)
* bug fix: moderately complex combinations of inline expansions could
be miscompiled if the result was declared to be dynamic extent.
* bug fix: on x86, SAP-REF of sizes greater than 8 bits with offsets of the
form (+ <variable> <integer>) were miscompiled under certain
circumstances.
* bug fix: in some cases no compiler note about failure to stack allocate
was emitted, even if the objects were in fact heap allocated.
* bug fix: minor violation of "otherwise inaccessible" rule for stack
allocation could cause objects users might reasonably expect to
be heap allocated to be stack allocated.
* bug fix: DESCRIBE signalled an error for generic functions under
certain circumstances. (thanks to Leslie Polzer)
* bug fix: Fixed spelling of an error message.

Changes since previous packaged version are too long to list,
they include 1,5 years of continuous development, adding features,
compiler optimizations, and fixing bugs. See log at

build the newer version. This should allow the package to be
included in bulk builds, and eliminate the troubles with other
Common Lisp systems being fragile WRT building this system.

New version has NetBSD/powerpc support (although I haven't adjusted
the Makefile due to lack of test machines) and now builds the
sb-posix package properly.

I would list the changes to the package here, but SBCL makes a new
release every month, and there are usually a dozen or more minor
changes per release. The previous version of this package is about
18 months old...
