-changes in sbcl-0.9.19 (1.0.0?) relative to sbcl-0.9.18:
+changes in sbcl-1.0.3 relative to sbcl-1.0.2:
+ * optimization: calls of the form (AREF FOO (+ INDEX <constant>)) now
+ produce more efficient code on the x86 if the compiler can determine
+ that (+ INDEX <constant>) does not require a bounds check and FOO
+ has an element type at least 8 bits wide.
+
+changes in sbcl-1.0.2 relative to sbcl-1.0.1:
+ * improvement: experimental support for mach exception handling on
+ x86/macos. requires building with :MACH-EXCEPTION-HANDLER feature
+ to use.
+ * improvement: support for GBK external format.
+ (thanks to Chun Tian (binghe))
+ * improvement: the debugger now displays variables that have been closed
+ over, in code compiled with (DEBUG 2) or higher
+ * improvement: support for executable cores on NetBSD (thanks to
+ Richard Kreuter)
+ * new feature: added a RESTART-FRAME debugger command
+ * new feature: new generic function SB-GRAY:STREAM-FILE-POSITION can
+ be used to provide an implementation for FILE-POSITION on Gray streams
+ (thanks to Eric Marsden)
+ * new feature: add syslog, openlog and closelog support to SB-POSIX
+ (thanks to Richard Kreuter)
+ * optimization: the function call overhead in code compiled with
+ a high DEBUG optimization setting is significantly
+ * bug fix: an error is signaled for attempts to use READ-SEQUENCE
+ for a (SIGNED-BYTE 8) stream and (UNSIGNED-BYTE 8) vector, or vice versa.
+ (thanks to Tony Martinez)
+ * bug fix: the initforms for DEFMETHOD &AUX parameters are only
+ evaluated once (reported by Kevin Reid)
+ * bug fix: the :SHOW-PROGRESS keyword parameter to SB-SPROF:WITH-PROFILING
+ works again (thanks to Kilian Sprotte)
+ * bug fix: an error is signaled for tagbodies with duplicate tags
+ (thanks to Stephen Wilson)
+ * bug fix: NIL can be used as a tagbody tag (thanks to Stephen Wilson)
+ * bug fix: Win32 port can now handle foreign code unwinding Lisp
+ stack frames from alien callbacks.
+ * bug fix: ATANH returned incorrect results on win32 (thanks to Pierre Mai)
+ * bug fix: SBCL works on Linux/ppc systems with a kernel configured to use
+ 65k pages (thanks to David Woodhouse)
+ * bug fix: fix SB-POSIX dirent and socket on NetBSD (thanks to Richard Kreuter)
+
+changes in sbcl-1.0.1 relative to sbcl-1.0:
+ * new platform: FreeBSD/x86-64, including support for threading.
+ * new feature: the compiler stores cross-referencing information
+ abount function calls (who-calls), macroexpansion (who-macroexpands)
+ and special variables (who-binds, who-sets, who-references) for code
+ compiled with (< SPACE 3). This information is available through the
+ sb-introspect contrib.
+ * new feature: users may subclass SEQUENCE, and have instances of
+ these classes interoperate with standard Common Lisp functions if
+ a number of methods are defined. (This feature is experimental
+ and the interface subject to change based on feedback from SBCL
+ users and the general community)
+ * improvement: sb-sprof traces call stacks to an arbitrary depth on
+ x86/x86-64, rather than the previous fixed depth of 8
+ * improvement: another pthread back-end of mutex "pthread-futex".
+ * bug fix: non-ascii command-line arguments are processed correctly
+ (thanks to Yaroslav Kavenchuk)
+ * bug fix: non-required arguments were not passed correctly when a method
+ defined using DEFMETHOD was called from a mop-generated method using
+ CALL-NEXT-METHOD (reported by Pascal Costanza)
+ * bug fix: recursion is now permitted in accessors through
+ SLOT-UNBOUND. (reported by Pascal Costanza)
+ * bug fix: an error was signaled at startup if the HOME environment
+ variable was defined, but had an empty value (reported by Peter Van Eynde)
+ * bug fix: non ordinary lambda-list keyword in ordinary lambda lists
+ signal a PROGRAM-ERROR, not a BUG.
+ * bug fix: SB-POSIX:READDIR works when built with large file support.
+ * bug fix: ENOUGH-NAMESTRING works relative to #p"/" as well. (thanks
+ to Marco Monteiro)
+ * enhancement: DESTRUCTURING-BIND lambda-list uses &BODY instead of &REST
+ for better automatic indentation support. (thanks to Matt Pillsbury)
+ * optimization: loading generic functions no longer takes O(n^2) time,
+ proportional to the amount of methods in the generic function
+ (reported by Todd Sabin and Jeremy Brown)
+ * optimization: the FIND and POSITION family of sequence functions
+ are significantly faster on arrays whose element types have been
+ declared.
+ * improvements to the Windows port:
+ ** Intermittent heap corruption problems have been fixed. (thanks
+ to Alastair Bridgewater)
+ ** TRACE :ENCAPSULATE NIL (and function end breakpoints)
+ work on Windows.
+ ** Lisp is able to unwind foreign exception frames from alien
+ callbacks. (thanks to Alastair Bridgewater)
+
+changes in sbcl-1.0 relative to sbcl-0.9.18:
+ * improvement: experimental support for threading on FreeBSD/x86.
+ (thanks to NIIMI Satoshi)
* improvement: runtime option --dynamic-space-size can be used
to set the size of the dynamic space reserved on startup.
* improvement: floating point modes in effect are now saved in
on Linux/x86
* improvement: added support for the Shift-JIS external format.
(contributed by NIIMI Satoshi)
+ * improvement: callbacks are supported on Linux/PPC. (thanks to
+ Joshua Ross)
* bug fix: compiler bug triggered by a (non-standard) VALUES
declaration in a LET* was fixed. (reported by Kaersten Poeck)
* bug fix: file compiler no longer confuses validated and already
(reported by Josip Gracin)
* bug fix: an error is signaled for attempts to displace arrays with
incompatible element types (thanks to Mario Mommer)
+ * bug fix: more correct handling of wide characters in debug info
+ (bug reported by Attila Lendvai and fixed by Juho Snellman)
+ * optimization: method calls with &OPTIONAL or &KEY arguments are faster
+ and don't cause extra consing
+ * optimization: MAP and MAP-INTO are significantly faster on vectors
+ whose elements types have been declared.
+ * Improvements to SB-SPROF:
+ ** Support for allocation profiling
+ ** Reduced profiling overhead, especially for long profiling runs
* Improvements to the Windows port:
** floating point exceptions are now reported correctly.
** stack exhaustion detection works partially.
