As a consequence of this change, the :IF-EXISTS :NEW-VERSION
option to OPEN now signals an error if the file being opened
exists; this may have an impact on existing code.
+ * fixed bug 190: RUN-PROGRAM should now work properly, respecting
+ signals received, on the PowerPC platforms (both Linux and
+ Darwin). (thanks to Pierre Mai for pointing out the location of
+ the error)
+ * several fixes on OS X: The system now builds and runs cleanly on
+ Panther (10.3), and works around sigreturn bug (no more SIGFPEs).
+ (thanks to Brian Mastenbrook)
* bug fix: DECODE-UNIVERSAL-TIME now accepts timezone arguments with
second-resolution: integer multiples of 1/3600 between -24 and 24.
(thanks to Vincent Arkesteijn)
behaviour, and in particular no longer treats all memory as being
exhausted when many small objects point to each other in a deeply
recursive manner.
+ * bug fix: arrays specialized on (UNSIGNED-BYTE 15) are now
+ recognized as being TYPEP their class.
+ * bug fix: the PUSHNEW documentation string has been corrected.
+ (thanks to Vincent Arkesteijn)
+ * bug fix: defaulting of the value for the last of an atypically
+ large number of multiple values being bound was not being
+ performed correctly on the Alpha or PPC platforms
* optimization: implemented multiplication as a modular
(UNSIGNED-BYTE 32) operation on the x86 backend.
* optimization: SEARCH on simple-base-strings can now be open-coded.
(see also contrib/compiler-extras.lisp for inspiration for
teaching the compiler about the Boyer-Moore algorithm).
+ * value, returned by MAX (and MIN) called with several EQUALP, but
+ not EQL, arguments now does not depend on compiler settings.
* fixed some bugs revealed by Paul Dietz' test suite:
** in stack analysis liveness information is propagated from
non-local entry points.
** DIRECTORY on logical pathnames is more correct.
** CLEAR-INPUT, CLEAR-OUTPUT, FINISH-OUTPUT and FORCE-OUTPUT
signal a TYPE-ERROR if their argument is not a stream.
+ ** READ-BYTE and WRITE-BYTE signal a TYPE-ERROR if their stream
+ designator argument does not designate a stream.
+ ** OPEN-STREAM-P and INPUT-STREAM-P on synonym streams work by
+ examining the synonym.
+ ** STREAM-ELEMENT-TYPE and FRESH-LINE on broadcast-streams now
+ work as specified.
+ ** OPEN and WITH-OPEN-STREAM allow opening streams with
+ element-type larger than ([UN]SIGNED-BYTE 32).

+changes in sbcl-0.8.9 relative to sbcl-0.8.8:
+ * deprecation of old extension: *DEBUG-PRINT-LEVEL* and
+ *DEBUG-PRINT-LENGTH* are now deprecated in favor of the new, more
+ general SB-DEBUG:*DEBUG-PRINT-VARIABLE-ALIST* mechanism. (This
+ should matter to you only if you rebind the printer control
+ variables and then find you want different bindings in the
+ debugger than in the ordinary execution of your program.)
+ * The runtime build system has been tweaked to support building
+ (on SPARC/SunOS) using a C compiler which invokes Sun's own
+ assembler and linker. (thanks to Nikodemus Siivola)
+ * Unbound, undefined, undeclared variables now trigger full
+ WARNINGs, not just STYLE-WARNINGs, on the assumption that this is
+ more often programmer error than deliberate exploitation of undefined
+ behaviour.
+ * optimization: the hash algorithm for strings has changed to one
+ that is less vulnerable to spurious collisions. (thanks to Juho
+ Snellman)
+ * optimization: VECTOR-POP, VECTOR-PUSH-EXTEND and REPLACE do less
+ needless bounds checking. (thanks to Juho Snellman)
+ * optimization: implemented multiplication as a modular
+ (UNSIGNED-BYTE 32) operation on the PPC backend.
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** ADJUST-ARRAY now copies the datum in a zero rank array if
+ required.
+ ** ADJUST-ARRAY no longer adjusts non-adjustable arrays.
+ ** MAKE-STRING-INPUT-STREAM accepts NIL as a value for :END.
+ ** MAKE-STRING-INPUT-STREAM functions correctly for strings with
+ element-type NIL.
+ ** CLEAR-INPUT accepts NIL and T for its (optional) stream
+ argument.
+ ** Ratios can now be printed correctly with *PRINT-BASE* bound to
+ 2, 8 or 16.
+ ** ECHO-STREAMs no longer attempt to echo the end of file value to
+ their output stream on EOF from read.
+ ** CONCATENATED-STREAM-STREAMS discards constituent streams which
+ have been read to end-of-file.
+ ** CLOSE works as expected on the null CONCATENATED-STREAM, and on
+ STRING-STREAMS.
+ ** Printing symbols with *PRINT-CASE* :CAPITALIZE respects the
+ description of determination of which consecutive characters
+ constitute a word.
+ ** Printing the "Space" character with escaping on now yields "#\\ ",
+ rather than "#\\Space", as mandated by ANSI 22.1.3.2.
+ ** Reading floating-point numbers with *READ-BASE* set to a number
+ less than 10 works correctly.
+ ** Reading floating-point numbers with *READ-BASE* set to a number
+ more than 10 works correctly.
+ ** Printing with *PRINT-READABLY* targets the standard readtable, not
+ the readtable currently in effect.
+
+changes in sbcl-0.8.10 relative to sbcl-0.8.9:
+ * Support for the forthcoming 2.0 version of the NetBSD kernel
+ running on x86 hardware has been added. (thanks to Perry
+ E. Metzger most immediately, and others for their past work)
+ * SBCL now runs on OpenBSD 3.4. (Thanks to Scott Parish; 3.4 is the
+ current release version; SBCL's OpenBSD support had been broken
+ since about the time of OpenBSD's switch to ELF binary format.)
+ * [placeholder for DX summary]
+ ** user code with &REST lists declared dynamic-extent, under high
+ speed or space and low safety and debug optimization policy.
+ * The manual has been converted to Texinfo format and the debugger
+ chapter from the cmucl manual has been added.
+ * A facility has been added to extract documentation strings from
+ sbcl and store them as Texinfo-formatted snippets for inclusion in
+ the manual (via Texinfo's @include directive)
+ * bug fix: compiler emitted division in optimized DEREF. (thanks for
+ the test case to Dave Roberts)
+ * bug fix: multidimensional simple arrays loaded from FASLs had fill
+ pointers. (reported by Sean Ross)
+ * bug fix: PROFILE output is printed nicely even for large numerical
+ values. (thanks to Zach Beane)
+ * bug fix: streams with element-type (SIGNED-BYTE <N>) for <N>
+ greater than 32 handle EOF correctly.
+ * bug fix: on X86 an immediate argument of the IMUL instruction is
+ correctly printed in disassembly. (thanks to Lutz Euler)
+ * bug fix: class slots in redefined classes preserve their old
+ values. (thanks to Bruno Haible and Nikodemus Siivola)
+ * bug fix: compilation of funcalls of CXX+R (e.g. CDDR) now
+ succeeds. (reported by Marco Baringer)
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** READ-SEQUENCE now works on ECHO-STREAMs.
+ ** RATIONALIZE works more according to its specification. (thanks
+ to Bruno Haible)
+
+changes in sbcl-0.8.11 relative to sbcl-0.8.10:
+ * fixed bug 313: source-transform for <fun-name> was erroneously
+ applied to a call of a value of a variable with name <fun-name>.
+ (reported by Antonio Menezes Leitao)
+ * fixed bug 307: The obsolete instance protocol ensures that
+ subclasses are properly obsoleted. (thanks to Nikodemus Siivola)
+ * on X86 fixed bug 298, revealed by Paul F. Dietz' test suite: SBCL
+ can remove dead unknown-values globs from the middle of the stack.
+ * added a new restart to *BREAK-ON-SIGNALS* handling to make it
+ easier to resume long computations after using *BREAK-ON-SIGNALS*
+ to diagnose and fix failures. (thanks to Nikodemus Siivola)
