** VALUES tranformer lost derived type.
changes in sbcl-0.8.8 relative to sbcl-0.8.7:
+ * minor incompatible change: parsing of namestrings on a physical
+ (Unix) host has changed; numbers after the final #\. in a
+ namestring are no longer interpreted as a version field. This is
+ intented to be largely invisible to the user, except that the
+ meaning of the namestring "*.*.*" has changed: it now refers to a
+ pathname with :TYPE :WILD :NAME #<pattern "*.*">. This namestring
+ should usually be replaced by
+ (make-pathname :name :wild :type :wild :version :wild)
+ with the added benefit that this is more likely to be portable.
+ 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)
+ * bug fix: functions =, /=, <, <=, >, >= did not check the argument
+ type when called with 1 argument; PEEK-CHAR checked type of
+ PEEK-TYPE only after having read first character from a
+ stream. (reported by Peter Graves)
+ * bug fix: the garbage collector now has much better locality
+ 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.
+ ** pathwise CAST removing failed when the CAST node did not start
+ a block.
+ ** INPUT-STREAM-P, OUTPUT-STREAM-P, STREAM-ELEMENT-TYPE and
+ OPEN-STREAM-P signal a TYPE-ERROR if their argument is not a
+ stream.
+ ** LOAD-LOGICAL-PATHNAME-TRANSLATIONS returns NIL if the logical
+ host is already defined.
+ ** RENAME-FILE works on streams instead of signalling an internal
+ type error.
+ ** PEEK-CHAR uses the current readtable when determining whether
+ or not a character is whitespace.
+ ** MERGE-PATHNAMES handles the case when the pathname does not
+ specify a name while the default-pathname specifies a version.
+ ** Pathnames now stand a better chance of respecting print/read
+ consistency.
+ ** Attempting to use standardized file system operators with a
+ pathname with invalid :DIRECTORY components signals a
+ FILE-ERROR.
+ ** OPEN :DIRECTION :IO no longer fails to work on non-existent
+ files.
+ ** 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:
+ * 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)
planned incompatible changes in 0.8.x:
* (not done yet, but planned:) When the profiling interface settles
