+changes in sbcl-0.9.2 relative to sbcl-0.9.1:
+ * SB-MOP:ENSURE-CLASS-USING-CLASS now accepts a class as the
+ :METACLASS argument in addition to a class name. (reported by
+ Bruno Haible for CMUCL, patch for CMUCL by Gerd Moellman)
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** Invalid dotted lists no longer raise a read error when
+ *READ-SUPPRESS* is T
+
+changes in sbcl-0.9.1 relative to sbcl-0.9.0:
+ * fixed cross-compiler leakages that prevented building a 32-bit
+ target with a 64-bit host compiler.
+ * fixed a bug in CLOSE :ABORT T: no longer attempts to remove files
+ opened with :IF-EXISTS :OVERWRITE.
+ * fixed bug 281: error for an invalid qualifier in a short-form method
+ combination method is not signalled until the faulty method is called.
+ * bug fix: iteration variable type inferrer failed to deal with open
+ intervals. (reported by Alan Shields)
+ * bug fix: dynamically loading (via LOAD-SHARED-OBJECT or similar)
+ "frameworks" on Mac OS X no longer causes an EXC_BAD_ACCESS if two
+ or more runtime options were provided to the sbcl binary.
+ * compiled code is not steppable if COMPILATION-SPEED >= DEBUG.
+ * contrib improvement: implement SB-POSIX:MKSTEMP (Yannick Gingras)
+ * optimization: there's now a fast-path for fixnum arguments in the
+ generic subtraction routines on x86/x86-64. (Thanks to Lutz Euler)
+ * optimization: the code generated on x86-64 is more compact thanks
+ to not outputting unneccessary prefix bytes. (Thanks to Lutz Euler)
+ * bug fix: floating-point exception handling now partly works on
+ x86-64. (Thanks to James Knight)
+ * improvement to the MIPS backend from Thiemo Seufer: C-style
+ 64-bit long long arguments and return values to alien functions
+ are now supported.
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** the type-error signalled from WARN has a filled-in DATUM slot.
+ ** the type-error required when a stream is not associated with
+ a file has the stream as its datum.
+ ** type-errors on single-floats on x86-64 no longer have
+ :INVALID-OBJECT as the datum
+ ** the type-errors signalled for invalid function names now have
+ a correct expected type
+ ** (SETF (DOCUMENTATION ... 'STRUCTURE)) no longer signals an error
+ for structures defined with a :TYPE. Documentation strings for
+ typed structures are no longer immediately discarded
+ ** FILE-STRING-LENGTH and STREAM-EXTERNAL-FORMAT now work on
+ broadcast streams and synonym streams. FILE-LENGTH now also works
+ on broadcast streams.
+
+changes in sbcl-0.9.0 relative to sbcl-0.8.21:
+ * incompatible change: the --noprogrammer option, deprecated since
+ version 0.7.5, has been removed. Please use the equivalent
+ --disable-debugger option instead.
+ * incompatible change: finalizers and *AFTER-GC-HOOKS* are now run with
+ interrupts enabled.
+ * incompatible change: support for *BEFORE-GC-HOOKS* (that have been
+ inoperational for a while now) has been completely removed.
+ * null lexical environments are now printed as #<NULL-LEXENV>,
+ significantly reducing the amount of clutter in typical backtraces.
+ * documentation on weak pointers, finalization, and after GC hooks
+ has been added to the manual.
+ * optimization: REPLACE on declared (UNSIGNED-BYTE 8) vectors, as well
+ as other specialized array types, is much faster. SUBSEQ and
+ COPY-SEQ on such arrays have also been sped up.
+ * optimization: EQL is now more efficient when at least other argument
+ is known to be of type (OR FIXNUM (NOT NUMBER)).
+ * fixed bug: the runtime is now less vulnerable to changes in the
+ size of the SBCL object on OS X, and virtual memory is reserved for
+ all spaces that need to be at a fixed address.
+ * fixed bug: finalizers are now thread-safe. (thanks to Gabor Mellis)
+ * fixed bug: finalizers and after GC hooks that cause consing are now
+ safe.
+ * fixed bug: compiler error messages and summaries are now printed to
+ *ERROR-OUTPUT*, not *STANDARD-OUTPUT*.
+ * fixed inference of the upper bound of an iteration variable.
+ (reported by Rajat Datta).
+ * fixed bug 211e: calling local functions with duplicated constant
+ keyword argument no longer causes a bogus style warning about an
+ unused variable.
+ * fixed bug 305: INLINE/NOTINLINE declaration no longer causes local
+ ftype declaration to be disregarded. (reported by Dave Roberts)
+ * fixed bug 373: caused by erronous compilation of references to alien
+ variables in the runtime on ppc/darwin.
+ * fixed bug 376: CONJUGATE type deriver.
+ * fixed infinite looping of ALIEN-FUNCALL, compiled with high DEBUG.
+ (reported by Baughn on #lisp)
+ * a cross-compiler bug on non-x86 platforms has been identified and
+ fixed. (thanks to Bruno Haible)
+ * improvements to the MIPS runtime code for increased stability.
+ (thanks to Thiemo Seufer)
+ * increased the maximimum compact environment size to allow
+ purify on images with large amounts of functions. (thanks to Cyrus Harmon)
+ * partial workaround for bug 135: don't name the function we're
+ calling for hairy cases of EVAL, so as not to accumulate one environment
+ entry per call to EVAL. (reported by Kevin Reid)
+ * improvements to the x86-64 disassembler. (thanks to Lutz Euler)
+ * optimization: type testing for non-vector arrays should be faster.
+ * fixed TRACE :ENCAPSULATE NIL, added support for :ENCAPSULATE NIL
+ on x86-64
+ * bug fix: setting 31st element of a bit vector to zero did not work
+ on Alpha-32.
+ * bug fix: redefining a class definition which failed due to a
+ previous accessor / function clash now works (but see BUGS entry
+ #380 for more problems in this area). (thanks to Zach Beane)
+ * the long form of DEFINE-METHOD-COMBINATION disables method group
+ checking when given a single method group with pattern *. (thanks
+ to Wendall Marvel)
+ * on x86 compiler supports stack allocation of results of simple
+ calls of MAKE-ARRAY, bound to variables, declared DYNAMIC-EXTENT.
+ * support for building and running on Mac OS X 10.4 "Tiger" has been added
+ ** Binaries built on Tiger will not run on 10.2 "Jaguar" currently
+ * fixed some bugs related to Unicode integration:
+ ** the restarts for recovering from input and output encoding
+ errors only appear when there is in fact such an error to
+ handle.
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** MISC.549 and similar: late transformation of unsafe type
+ assertions into derived types caused unexpected code
+ transformations.
+ ** SCALE-FLOAT type deriver is less wrong.
+ ** type derivers for EXP, LOG and similar functions compute result
+ types for complex arguments better.
+ ** (MISC.563) CONJUGATE type deriver works for very restricted
+ complex types.
+ ** out-of-line type testers for character strings are available.
+ ** EQUAL compiler transform understands specialness of objects
+ of type BIT-VECTOR.
+ ** accessing double-floats stored on the stack now works on x86-64.
+ ** debugger internals could sometimes create invalid lispobjs,
+ resulting in GC crashes.
+ ** MISC.548: type check weakening can convert required type into
+ optional.
+ ** initialization forms for bindings are not in scope of free special
+ declarations.
+
changes in sbcl-0.8.21 (0.9alpha.1?) relative to sbcl-0.8.20:
* incompatible change: thread support for non-NPTL systems has
been removed - locking is buggy and unreliable. A threaded
no longer processed with LOAD, but by READ and EVAL; hence the
global optimization policy, startup package, readtable, etc,
can be set by them.
+ * The .fasl file format number has been incremented because of
+ various incompatible changes.
* internal entry point details and argument counts no longer appear
in backtraces unless explicitly requested by setting
SB-DEBUG:*SHOW-ENTRY-POINT-DETAILS*.
