+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

+ 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)
+

+ * 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.

+ core, and restored on startup.
+ * improvement: GET-INTERNAL-REAL-TIME now reports the time since
+ startup, not time since first call to GET-INTERNAL-REAL-TIME.
+ * improvement: SAVE-LISP-AND-DIE explicitly checks that multiple
+ threads are not running after *SAVE-HOOKS* have run.

+ (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
+ dumped structurres. (reported by Kaersten Poeck)
+ * bug fix: ADJUST-ARRAY :FILL-POINTER T on an array without a

+ Lars Brinkhoff)
+ * bug fix: disassemly of funcallable instances works.
+ * bug fix: single stepping on PPC.
+ * bug fix: fix thread-safety problems in the type system (generally

+changes in sbcl-0.9.18 (1.0.beta?) relative to sbcl-0.9.17:
+ * enhancement: SB-POSIX now supports cfsetispeed(3), cfsetospeed(3),
+ cfgetispeed(3), cfgetospeed(3), and related constants. (thanks to
+ Max-Gerd Retzlaff)
+ * bug fix: two potential GC deadlocks affecting threaded builds.
+ * bug fix: (TYPEP #\A '(NOT (MEMBER #\" #\{ #\:))) now correctly
+ returns T (reported by Anton Kazennikov)
+ * bug fix: the STORE-VALUE restart of CHECK-TYPE works correctly
+ with non-variable places
+ * bug fix: remove a race condition in the setting of
+ funcallable-instance functions, this should make threaded CLOS
+ code more stable against memory faults.
+ * bug fix: corruption of specials when unbinding is interrupted by an
+ asynchronous unwind (reported by Hannu Koivisto)
+ * improvement: the debugger will now also display local variables that
+ are only used once, for code compiled with a DEBUG optimization quality
+ of 2 or higher.
+
+changes in sbcl-0.9.17 (0.9.99?) relative to sbcl-0.9.16:
+ * feature: weak hash tables, see MAKE-HASH-TABLE documentation
+ * incompatible change: External-format support for FFI calls. The
+ SB-ALIEN:C-STRING no longer implies an ASCII
+ external-format. Instead the string is subject to external-format
+ conversion. Additionally return values of type SB-ALIEN:C-STRING
+ are by default of type (SIMPLE-ARRAY CHARACTER), not
+ SIMPLE-BASE-STRING. For an alien type that behaves like the old
+ SB-ALIEN:C-STRING type, use (SB-ALIEN:C-STRING :EXTERNAL-FORMAT
+ :ASCII :ELEMENT-TYPE BASE-CHAR). (thanks to Yaroslav Kavenchuk)
+ * incompatible change: SB-EXT package no longer contains the
+ following unused symbols: *GC-NOTIFY-AFTER*, *GC-NOTIFY-BEFORE*,
+ *GC-NOTIFY-STREAM*, *ERROR-PRINT-LENGTH*, *ERROR-PRINT-LEVEL*,
+ *ERROR-PRINT-LINES*
+ * incompatible change: the single-stepper is no longer available
+ on Alpha, Mips and Sparc platforms.
+ * minor incompatible change: the direct superclasses of
+ SB-MOP:FUNCALLABLE-STANDARD-OBJECT are (FUNCTION STANDARD-OBJECT),
+ not (STANDARD-OBJECT FUNCTION). This makes the
+ class-precedence-lists of GENERIC-FUNCTION and
+ STANDARD-GENERIC-FUNCTION comply with the requirement of ANSI
+ 1.4.4.5.
+ * minor incompatible change: the default stream external format on
+ non-unicode SBCL is no longer detected from the locale, but is always
+ ISO-8859-1
+ * new feature: Add a version of evaluator that uses an interpreter instead
+ of the compiler. EVAL still uses the compiler by default, to switch it
+ to use the interpreter, set the value of the variable
+ SB-EXT:*EVALUATOR-MODE* to :INTERPRET.
+ * minor incompatible change: the single-stepper REPL has been merged
+ with the normal debugger (see the "Stepping" heading of the debugger help
+ for more details). The debugger command STEP will no longer switch
+ to the single-stepper REPL.
+ * bug fix: ENOUGH-NAMESTRING on pathnames with no name and a pattern
+ for a type now works.
+ * bug fix: loading of default sysinit file works. (thanks to Leonid
+ Slobodov)
+ * bug fix: better detection of circularities in the file-compiler.
+ (reported by Marco Monteiro)
+ * bug fix: the CL pathname functions now work with files that have
+ non-ASCII characters in their names (thanks to Yaroslav Kavenchuk)
+ * bug fix: The :PTY argument for RUN-PROGRAM will now work on
+ systems with Unix98 pty semantics.
+ * bug fix: ASDF-INSTALL will now work with bsd tar.
+ * bug fix: ASDF-INSTALL uses GNU tar on Solaris (thanks to Josip
+ Gracin).
+ * bug fix: timers expiring in dead threads no longer cause a
+ type-error (reported by Paul "Nonny Mouse").
+ * bug fix: thanks to more lightweight single-stepper instrumentation,
+ code compiled with (DEBUG 3) will compile and execute significantly faster,
+ and will have more accurate type-inferencing than before
+ * bug fix: SLOT-VALUE optimizations are no longer done on method parameters
+ whose bindings are modified
+ * improvements to the win32 port (thanks to Yaroslav Kavenchuk):
+ ** bug fix: arguments to RUN-PROGRAM are escaped correctly
+ ** replace dummy implementations of CL:MACHINE-INSTANCE and
+ CL:SOFTWARE-VERSION with proper version
+

+ as well, allowing compiler-macros for SETF-functions to expand.
* enhancement: step-instrumentation no longer wraps known
single-value functions with multiple-value context, allowing
better type inference.

* bug fix: fixed input, output and error redirection in RUN-PROGRAM
for win32. (thanks to Mike Thomas and Yaroslav Kavenchuk)
+ * bug fix: #368: incorrect use of expressed vs. upgraded array
+ element type.
+ * bug fix: #306a: more precise unions of array types.
+ * thread-safety improvements:
+ ** CONDITION-WAIT could return early on Linux, if the thread was
+ interrupted and subsequently continued with SIGCONT.
+ ** STABLE-SORT and ADJUST-ARRAY were not reentrant.
