changes in sbcl-1.1.8 relative to sbcl-1.1.7:
* notice: The implementation of MAP-ALLOCATED-OBJECTS (the heart of
ROOM, plus a few SB-INTROSPECT functions) has been completely
rewritten; it may now exhibit different bugs than before.
* new feature: minimal runtime/compiler intrastructure support for SSE
SIMD values, as SB-EXT:SIMD-PACK. Enabled on x86-64 via the build-time
feature :sb-simd-pack. This should enable intrinsics extensions as
libraries, without patching SBCL itself. Thanks to Alexander Gavrilov
for maintaining a branch for so long.
* enhancement: RUN-PROGRAM supports a :DIRECTORY argument to set
the working directory of the spawned process.
(lp#791800) (patch by Matthias Benkard)
* enhancement: boxed vectors (vectors of T or of FIXNUM) can now be
stack-allocated on PPC.
* enhancement: "fixed objects" can now be stack-allocated on PPC.
* enhancement: WITH-PINNED-OBJECTS no longer conses on PPC/GENCGC.
* enhancement: (sb-introspect:find-definition-sources-by-name x :vop) now
also returns VOPs which do not translate any functions, and finds
defoptimizer types ir2convert and stack-allocate-result.
* enhancement: better type derivation for APPEND, NCONC, LIST.
(lp#538957)
* enhancement: MAP-ALLOCATED-OBJECTS (the heart of ROOM) now walks the
heap in a manner similar to the GC rather than its previous ad-hoc
scheme, and is therefore no less and possibly more accurate.
* fixes and enhancements related to Unicode:
** the character database information has been updated to Unicode 6.2;
** support for canonical and compatibility decomposition of characters has
been added, along with support for primary composition;
** support for Unicode normalization forms of strings (NFC, NFKC, NFD and
NFKD) has been included;
** querying the character database for code points not defined by Unicode
gives less wrong answers (lp#1178038, reported by Ken Harris)
* enhancement: print intermediate evaluation results for some ASSERTed
expressions. (lp#789497) (patch by Alexandra Barchunova)
* enhancement: x86-64 disassemblies are annotated with unboxed constant
values when there are references to (RIP-relative) unboxed constants.
* bug fix: type derivation for LOG{AND,IOR,XOR} scales linearly instead
of quadratically with the size of the input in the worst case.
(lp#1096444)
* bug fix: handle errors when initializing *default-pathname-defaults*,
sb-ext:*runtime-pathname*, sb-ext:*posix-argv* on startup, like character
decoding errors, or directories being deleted.
* bug fix: Loading a core with a discontiguous dynamic space now correctly
computes the amount of dynamic space used.
* bug fix: disassembler missing ",8" on SHLD
* bug fix: backtracing through INTERNAL-ERROR signal handlers on systems
that provide an "invalid" stack frame link for the signal handler
itself now use the saved-fp-and-pc mechanism to pick up from the stack
frame in the interrupt (signal) context. This is known to affect
threaded FreeBSD/x86-64.
* bug fix: some LOOP statements couldn't be compiled.
(lp#1178989)
* bug fix: sb-sequence:dosequence works on literal vectors.
* bug fix: errors in generic arithmetic show the assembly routine's
caller on x86 and x86-64. (lp#800343)
* bug fix: Compile-time type errors should never result in COMPILE-FILE
failure. (lp#943953)
* bug fix: Known bad local calls do not cause strange failures when
emitting or dumping code. (lp#504121)
* bug fix: Multiply-inlined structure constructor don't cause IR2-time
codegen errors: type checks are inserted as necessary. (lp#1177703)
* bug fix: Unsigned modular arithmetic is correctly converted into signed
modular arithemtic (mostly to exploit fixnum-width VOPs). (lp#1026634)
* bug fix: a combination of inlined local function with &optional and
recursion no longer causes undescriptive compiler errors. (lp#1180992)
* bug fix: sub-word BOOLEAN alien types now disregard higher order bits
when testing for non-zero-ness.
* bug fix: (CONCATENATE 'null ...) no longer fails for generic sequences.
(lp#1162301)
* bug fix: Type mismatch for the value of conditional expressions are
correctly reported when detected at compile-time, instead of complaining
about a constant NIL (similar for non-EQ-comparable catch tags).
* bug fix: Referring to INLINE global functions as values should not result
in a compilation failure. (lp#1035721)
* optimization: faster ISQRT on fixnums and small bignums
* optimization: faster and smaller INTEGER-LENGTH on fixnums on x86-64.
* optimization: On x86-64, the number of multi-byte NOP instructions used
for code alignment is now always minimal.
* optimization: On 64-bit targets, the compiler generates much faster
code for type checks for types known at compile time that are smaller
than (SIGNED-BYTE 64) or (UNSIGNED-BYTE 64) and larger than FIXNUM, and
their COMPLEX variants.
* optimization: On x86 targets, more uses of ALIEN-FUNCALL during cross
compilation now inline the INVOKE-WITH-SAVED-FP-AND-PC dance.
* optimization: ROOM no longer conses so egregiously on non-x86oid
systems.
* optimization: associative bitwise operations reassociate patterns like
(f (f x k1) k2) to expose (f x (f k1 k2)). Same for + and * of
rational values.
* optimization: quasiquote expressions now perform more constant folding,
instead of consing equal lists at runtime. (lp#1026439)
* optimization: local call analysis of inlined higher-order function
should converge more quickly, resulting in better code for complex
functions.
* optimization: On x86-64, medium (word-sized but wider than 32 bits)
integer constants are handled more cleverly, especially when they
can be represented as sign-extended (signed-byte 32). (Based on a
patch by Douglas Katzman)
* optimization: IF/IF conversion should reliably result in sane code
when (some of) the results of the inner IF are always false or
always true.
* optimization: On x86oids, variable right shifts of machine words are
compiled into straight SAR/SHR, instead of going through the generic
VOP. (lp#1066204)
changes in sbcl-1.1.7 relative to sbcl-1.1.6:
* enhancement: TRACE :PRINT-ALL handles multiple-valued forms.
(lp#457053)
* bug fix: :allocation slot option works for condition slots
(lp#1049404)
* bug fix: redefining conditions does not lead to multiple evaluations of
hairy slot initfunctions anymore (lp#1164969)
* bug fix: CLASS-DIRECT-DEFAULT-INITARGS now works for condition classes
(lp#1164970)
* bug fix: function constants now work as initforms and default initarg
values of conditions (lp#539517)
* bug fix: svref/(setf svref) on symbol macros don't crash the compiler
anymore. (Minimal test case provided by James M. Lawrence on sbcl-devel)
* bug fix: no more bogus ## references when pretty printing backquoted
forms with non-trivial structure sharing. (lp#1161218)
* bug fix: Don't signal an error on (setf (documentation nil 'function)
"doc"). Signal a style-warning instead when trying to set documentation
of NIL for all other documentation types. (Reported by Zach
Beane; regression since 2e52fa05.)
* bug fix: modular arithmetic involving large constants and conditionals
should no longer result in spurious dead code elimination. (Reported by
Eric Marsden).
* bug fix: our mach exception handler can seemingly called very early in
the program execution process on OS X 10.8.0. Try and handle that case
robustly, without potentially leaking mach ports too much.
* optimization: LOGBITP and LOGTEST optimizations from x86 ported to x86_64.
changes in sbcl-1.1.6 relative to sbcl-1.1.5:
* enhancement: the continuable error when defknown-ing over extant
fndb entries can be ignored by passing :overwrite-fndb-silently t
as a keyword argument to sb-c:defknown (after attributes). Useful
to allow defknown to be re-loaded. Use with :allow-other-keys t
for backward compatibility.
* optimization: compiler is much faster in compiling SVREF and (SETF SVREF)
forms.
* bug fix: Prevent a make-array transform from modifying source forms
causing problems for inlined code. Thanks to Bart Botta.
(regression since 1.0.42.11-bis)
* bug fix: clear-output calls the correct gray stream routine,
sb-gray:stream-clear-output. (lp#1153257)
* bug fix: an error is signalled for an invalid format modifier: ~<~@>.
(lp#1153148)
* bug fix: Better error messages for package operations (lp#1154776)
* bug fix: delete-package on a nonexistent package should signal a cerror.
(regression since 1.0.37.44).
* bug fix: accessing &MORE (stack allocated &REST) arguments checks bounds.
(lp#1154946, lp#1072112)
* bug fix: compiling make-array no longer signals an error when the
element-type is an uknown type, a warning is issued instead.
Thanks to James Kalenius (lp#1156095)
* bug fix: SEARCH on generic (non-VECTOR non-LIST) sequence types no longer
produces wrong results for some inputs. (Thanks to Jan Moringen.)
(lp#1153312)
changes in sbcl-1.1.5 relative to sbcl-1.1.4:
* minor incompatible change: SB-SPROF:WITH-PROFILING no longer loops
by default.
* new feature: package local nicknames. See manual for details.
* new feature: SB-EXT:MAP-DIRECTORY provides a powerful interface for
directory traversal: it is the backend used by SBCL for CL:DIRECTORY.
* enhancement: easier to use restarts for resolving name-conflicts
resulting from IMPORT, EXPORT, or USE-PACKAGE.
* enhancement: variant DEFPACKAGE forms now signal a full error with
restarts provided for resolving the situation. (lp#891351)
* enhancement: by setting SB-EXT:*ON-PACKAGE-VARIANCE* appropriately variant
DEFPACKAGE forms can now signal a full error with restarts provided for
resolving the situation. See manual for details. (lp#891351)
* enhancement: make-random-state now uses CryptGenRandom as a seed on Windows.
(Thanks to Anton Kovalenko.) (lp#1102748)
* enhancement: backtrace improvements
** secondary CLOS dispatch functions have better debug names (lp#503081)
** easier to read method names in backtraces. See
SB-DEBUG:*METHOD-FRAME-STYLE*.
** SB-DEBUG:PRINT-BACKTRACE and SB-DEBUG:LIST-BACKTRACE are available as
forwards-compatible replacements for SB-DEBUG:BACKTRACE and
SB-DEBUG:BACKTRACE-AS-LIST.
** SB-DEBUG:*SHOW-ENTRY-POINT-DETAILS** has been deprecated, as the same
information is available in less intrusive form as frame annotations.
* enhancement: SB-POSIX now provides MAP-ANON.
* enhancement: test-suite results are colorized, failures in red, unexpected
success in green. Works on Windows and on terminals with ANSI escape code
support. Can be disabled with --no-color.
* optimization: SB-CONCURRENCY:QUEUE implementation is more efficient.
(thanks to James M. Lawrence)
* bug fix: no more unused variable style warnings from RESTART-CASE
macroexpansion (lp#1113859)
* bug fix: no more unused variable style warnings when loading
sb-bsd-sockets.asd (lp#1114681)
* bug fix: deleting a package removes it from implementation-package
lists of other packages.
* bug fix: SB-SPROF:WITH-PROFILING is now usable in the Slime REPL on Darwin.
This does not fix the occasional "interrupt already pending" issue, though.
* bug fix: (setf (documentation 'x 'function)) and
(setf (documentation #'x t)) set documentation in different places.
(regression since 1.0.43.63)
* bug fix: build on newer glibc. (lp#1095036)
changes in sbcl-1.1.4 relative to sbcl-1.1.3:
* optimization: LOOP expressions using "of-type character" have slightly
more efficient expansions.
* bug fix: very long (or infinite) constant lists in DOLIST do not result
in very long compile times or heap exhaustion anymore. (lp#1095488)
* bug fix: `#3(1) is read as #(1 1 1), not as #(1). (lp#1095918)
* bug fix: adjust-array ignored :initial-element for simple-vectors.
(lp#1096359)
* bug fix: optimizations to MAKE-INSTANCE with literal list initargs no
longer cause infinite loops (on circular data) or violate eqlity
constraints. (lp#1099708)
* bug fix: FIRST was not being open coded. (regression from 1.1.0)
changes in sbcl-1.1.3 relative to sbcl-1.1.2:
* enhancement: warnings about bad locale settings, LANG, LC_CTYPE, etc.
(lp#727625)
* enhancement: support for C-c to interrupt the foreground thread
on Windows. (Thanks to Anton Kovalenko.)
* enhancement: STDCALL alien callbacks. (Thanks to Anton Kovalenko.)
* enhancement: Safepoint builds on POSIX platforms can now optionally be
built without pseudo-atomic sequences and their run-time overhead.
* enhancement: Threads created outside of Lisp can enter Lisp through
alien callbacks and appear as Lisp threads for the duration of that
function invocation. On safepoint builds only.
* enhancement: Miscellaneous improvements to namestrings and underlying
calls to OS functions for file system access on Windows. (Thanks to
Anton Kovalenko.)
* enhancement: The MSI installer support for Windows now uses Windows
Installer XML at least version 3.5 and includes various usability
improvements. (Thanks to Dmitry Kalyanov and Anton Kovalenko.)
* enhancement: The sb-bsd-sockets contrib now supports non-blocking-mode
on Windows. (Thanks to Anton Kovalenko.)
* enhancement: The Windows backend now supports the x86-64 platform.
(Thanks to Anton Kovalenko.)
* bug fix: fasls are now once again directly executable (on platforms
supporting shebang lines, with a suitably-installed sbcl).
* bug fix: make.sh --help no longer runs clean.sh. (lp#937001)
* bug fix: Fix CAS access to slots of direct instances of structure classes
in the presence of subclasses sharing the same conc-name.
* bug fix: Logical pathname namestrings on Windows have been changed to
be lower-case, to minimize differences between POSIX and Windows.
changes in sbcl-1.1.1 relative to sbcl-1.1.0:
* enhancement: WITH-COMPILATION-UNIT no longer grabs the world-lock.
(COMPILE and COMPILE-FILE still do.)
* optimization: the SPARC backend now supports the precise generational
(GENCGC) garbage collection. Enabled by default on Solaris/SPARC and
Linux/SPARC. Thanks to Raymond Toy (via CMUCL).
* enhancement: add experimental support for the SB-THREAD feature and the
timer facility on Windows. Thanks to Dmitry Kalyanov and Anton Kovalenko.
Threads are enabled by default, and this version of SBCL is considered
to be the last and final release to officially support building with
threads disabled.
* optimization: The compiler no longer rotates loops in some cases where
this transformation actually lead to worse code being generated.
* bug fix: SB-CLTL2:MACROEXPAND-ALL correctly handles shadowing of
symbol-macros by lexical bindings.
* bug fix: stack allocation was prevented by high DEBUG declaration in
several cases.
* bug fix: SB-EXT:GC-LOGFILE signaled an error when no logfile was set.
(thanks to SANO Masatoshi)
* bug fix: PARSE-NATIVE-NAMESTRING performed non-native parsing when
:JUNK-ALLOWED was true.
* bug fix: type derivation inferred overly conservative types for
unions of array types. (lp#1050768)
changes in sbcl-1.0.54 relative to sbcl-1.0.53:
* minor incompatible changes:
** RENAME-FILE on a symbolic links used to rename the linked-to file
instead of the link.
** DELETE-DIRECTORY on symbolic link to a directory used to delete the
directory, but now signal an error instead. Use TRUENAME to resolve the
pathname if you wish to delete the linked directory, and DELETE-FILE if
you wish to delete the
** The internal SB-THREAD::SPINLOCK API has been deprecated, and using
symbols associated with it will trigger a compile-time warning.
* thread-related enhancements:
(This work has been funded by the SBCL Threading 2011 IndieGoGo campaign.
Many thanks to generous donors!)
** Threading is now more reliable on non-Linux platforms. We still don't
consider threads on non-Linux platforms good enough to enable them by
default, but they're in a clearly better shape now.
** Deadlines supported now on all platforms.
** All blocking functions in the threading API now have a :TIMEOUT
argument.
** Semaphore notification objects have been added to SB-THREAD.
** SB-CONCURRENCY contrib now includes Allegro-style GATE objects.
** SB-EXT:COMPARE-AND-SWAP has been extended to support SLOT-VALUE,
STANDARD-INSTANCE-ACCESS, and FUNCALLABLE-STANDARD-INSTANCE-ACCESS.
** Users can now defined new places usable with SB-EXT:COMPARE-AND-SWAP
using an API anologous to defining new SETFable places.
* GC-related enhancements and bug fixes:
** --dynamic-space-size and --control-stack-size now understand Kb, Mb,
and Gb suffixes. Default is megabytes as before.
** on GENCGC targets, the default dynamic space size is now 512Mb for
32-bit systems, and 1Gb for 64-bit systems. (OpenBSD/x86-64 is the only
exception, defaulting to mere 444Mb to fit under default ulimits.) The
new defaults are in place to prevent hitting swap on low-end systems.
Use build-time option --dynamic-space-size to build an SBCL with
another default, or the runtime option to adjust the size at startup: a
good size is at most equal to the amount of physical memory the system
has.
** on GENCGC targets, nursery and generation sizes now default to 5% of
dynamic-space size.
** on GENCGC targets, SB-KERNEL:MAKE-LISP-OBJ no longer categorically
refuses to create SIMPLE-FUN objects.
** on 64-bit GENCGC targets, setting the nursery size above 4Gb now works.
(lp#870868)
** on CHENEYGC targets, SB-KERNEL:MAKE-LISP-OBJ now does the same
validation of pointer objects as GENCGC does, instead of a
comparatively weak bounds-check against the heap spaces.
* SB-BSD-SOCKETS bug fixes:
** GET-PROTOCOL-BY-NAME had a significant memory leak.
** GET-HOST-BY-NAME and GET-HOST-BY-ADDRESS small amounts of memory on
systems with getaddrinfo().
** GET-HOST-BY-NAME and GET-HOST-BY-ADDRESS weren't thread or interrupt
safe outside systems with getaddrinfo().
* enhancement: ASDF has been updated 2.019.
* enhancement: special-case TCO prevention for functions which never return
extended to untrusted types, keeping one more frame's worth of debug
information around in many cases.
* enhancement: debug-names of anonymous and local function are more
descriptive. Affects backtraces and SB-SPROF results. (lp#805100)
* enhancement: on win32, ABS of complex floats guards better against
overflows. (lp#888410)
* enhancement: RUN-PROGRAM now distinguishes exec() failing from child
process exiting with code 1. (lp#676987)
* enhancement: convenience function SET-SBCL-SOURCE-LOCATION for informing
the system where on the filesystem the SBCL sources themselves are
located. (Thanks to Zach Beane)
* enhancement: the compiler is now able to derive tighter bounds for
floating point numbers in some cases. (Thanks to Lutz Euler, lp#894498)
* bug fix: on 64-bit targets, atomic-incf/aref does index computation
correctly, even on wide-fixnum builds. (lp#887220)
* bug fix: (DIRECTORY "foo/*/*.*") did not follow symlinks in foo/ that
resolved to directories.
* bug fix: type mismatch when assigning to lexical variables no longer
result in fasl-dumping internal type objects. (lp#890750)
* bug fix: type mismatch on (SETF AREF) and function return values no
longer result in fasl-dumping internal type objects.
* bug fix: With several combinations of argument types, for example (EXPT
<integer> <(complex double)>), EXPT now uses double-precision throughout
instead of partially calculating only to single-precision. (lp#741564;
thanks to Lutz Euler)
* bug fix: SYMBOL-VALUE-IN-THREAD is no longer able to construct bogus
objects when interrupted by GC on PPC.
changes in sbcl-1.0.42 relative to sbcl-1.0.41
* build changes
** Cross-compilation host is now specified to make.sh using
command-line argument --xc-host=<command> instead of a positional
argument. (thanks to Daniel Herring)
** Install location can be specified to make.sh using command-line
argument --prefix=<path>. (lp#550889s, thanks to Daniel Herring)
* optimization: The default implementation of
COMPUTE-DISCRIMINATING-FUNCTION does much less wasted work.
* enhancement: Explicit memory barrier operations are now available for use
by multithreaded code. See documentation for details.
* enhancement: Experimental support for threading on Linux/PPC.
* bug fix: RENAME-PACKAGE returns the package. (Thanks to Eric Marsden)
* bug fix: EXPT signals an error if first argument is a zero and second
argument is a floating point zero. (lp#571581, thanks to Roman Marynchak)
* bug fix: DEFTYPE signals an error for non-list lambda-lists.
(lp#576594, thanks to Roman Marynchak)
* bug fix: make ASDF-INSTALL compatible with the now-included ASDF2.
(lp#612998, reported by Phil Hargett; patch from Jim Wise)
changes in sbcl-1.0.38 relative to sbcl-1.0.37:
* incompatible change: Thread names are now restricted to SIMPLE-STRINGs
like for any other thread-related datastructure, MUTEX, etc. (lp#547095)
* deprecation: the SB-QUEUE contrib was merged into the SB-CONCURRENCY
contrib module. New code should depend on SB-CONCURRENCY, not SB-QUEUE.
* deprecation: SB-THEAD:GET-MUTEX was deprecated in favor of
SB-THREAD:GRAB-MUTEX.
* new contributed module: SB-CONCURRENCY is a new contrib; it's supposed to
contain additional data structures and tools for concurrent programming;
at the moment it contains a lock-free queue, and a lock-free mailbox
implementation.
* new feature: added SB-THREAD:GRAB-MUTEX; it's like the now deprecated
GET-MUTEX but takes &key rather than &optional parameters. Also added
:TIMEOUT argument to GRAB-MUTEX on non-sb-lutex platforms like Linux and
BSD.
* new feature: added SB-THREAD:TRY-SEMAPHORE, a non-blocking variant of
SB-THREAD:WAIT-ON-SEMAPHORE.
* new feature: SB-EXT:ATOMIC-DECF has been added as a companion to
SB-EXT:ATOMIC-INCF.
* new feature: a CANCEL-DEADLINE is associated with DEADLINE-TIMEOUT
conditions to defer the deadline for forever.
* enhancement: *STANDARD-OUTPUT*, *STANDARD-INPUT*, and *ERROR-OUTPUT* are
now bivalent.
* enhancement: errors from NO-APPLICABLE-METHOD and
NO-PRIMARY-METHOD now have a RETRY restart available to retry the
generic function call.
* enhancement: SB-BSD-SOCKET improvements
** sockets and socket streams now have a more informative printed
representation based on the corresponding SOCKET-NAME and
SOCKET-PEERNAME.
** SOCKET-MAKE-STREAM once more supports the :AUTO-CLOSE option.
(lp#540413)
** SOCKET-CLOSE now accepts :ABORT argument, which is passed on to
CL:CLOSE when appropriate, and no longer disassociates the stream
from the socket if close failed. (lp#543951)
* improvements to the instrumenting profiler
** new feature: report per-function GC overhead. (thanks to John Fremlin)
** optimization: counters no longer use locks for the overflow mode.
** bug fix: whenever a profiling counter wrapped into overflow mode, it
incurred an off-by-one miscount.
* enhancement: improved MAKE-HASH-TABLE documentation (lp#543473)
* enhancement: improved DEFMETHOD pretty-printing.
* enhancement: perform range reduction when arguments are too large for
x87's transcendentals (instead of returning 0). (lp#327192)
* enhancement: eliminate some spurious TYPE-WARNINGs. Should help with
some of CL-PPCRE's macros. (lp#570079)
* enhancement: our machine code is slightly less hostile to valgrind on
x86-64.
* enhancement: up-to-date versions of NetBSD-current are supported. (Thanks
to Robert Swindells and Aleksej Saushev)
* bug fix: correct restart text for the continuable error in MAKE-PACKAGE.
* bug fix: a rare case of startup-time page table corruption.

* bug fix: Fix lost wakeup bug between SB-THREAD:CONDITION-WAIT and
CONDITION-NOTIFY on Linux. See threads "lost wakeup in condition-wait /
condition-notify" (Feb 2010) and "Condition-Wait, Deadline handler, waking
up itself" (March 2010) for further details.
* bug fix: allow forward FIND and POSITION on lists to elide checking :END
against length of the list if the element is found before the specified
END is reached. (thanks to Alec Berryman, lp#554385)
* bug fix: errors signalled during package graph modification no longer
block FIND-SYMBOL and FIND-PACKAGE in other threads. (lp#511072)
* bug fix: SB-POSIX build was broken when SBCL was compiled without the
:SB-DOC feature. (lp#552564)
* bug fix: SB-INTROSPECT build issues on GENGC/PPC. (lp#490490)
* bug fix: more robust runtime executable path detection. (lp#375549)
* bug fix: GCD always returns positive values. (lp#413680)

denormals.
* bug fix: We were too eager in eliding range reduction tests on x87.

types) could result in type mismatches during compilation.
changes in sbcl-1.0.37 relative to sbcl-1.0.36:
* enhancement: Backtrace from THROW to uncaught tag on x86oids now shows
stack frame thrown from.
* enhancement: WITH-COMPILATION-UNIT :POLICY allows restricting changes to
compiler optimization qualities inside dynamic extent of its body.
* enhancement: LOAD-LOGICAL-PATHNAME-TRANSLATIONS can be used to load
translations from SYS:SITE;<HOST>.TRANSLATIONS.NEWEST (thanks to Michael
Weber)
* optimization: SLOT-VALUE and (SETF SLOT-VALUE) take advantage of
constraint propgation, allowing better compilation eg. when used to
access structures with WITH-SLOTS. (lp#520366)
* optimization: the compiler is now more aware of the type of the underlying
storage vector for multidimensional simple arrays resulting in better code
for accessing such arrays.
* optimization: passing NIL as the environment argument to TYPEP no longer
inhibits optimizing it. (lp#309788)
* optimization: more efficient register usage when handling single-float
arguments on x86-64. (thanks to Lutz Euler)
* optimization: ADJUST-ARRAY and STABLE-SORT on vectors no longer use
pre-allocated temporary vectors. (lp#496249)
* bug fix: Fix compiler error involving MAKE-ARRAY and IF forms
in :INITIAL-CONTENTS. (lp#523612)

threads started during profiling. (lp#472499)
* bug fix: SB-INTROSPECT test failure when building without SB-EVAL feature.
(lp#535658)
* bug fix: SB-CLTL2:DECLARATION-INFORMATION did not take
SB-EXT:RESTRICT-COMPILER-POLICY into account. (lp#313337)
* bug fix: Comma inside a backquoted array or structure resulted in nonsense
values instead of signaling an error. (lp#309093)

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
http://www.sbcl.org/all-news.html
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...
