+ * optimization: more efficient type-checks for FIXNUMs when the value
+ is known to be a signed word on x86 and x86-64.
+ * improvement: failure to provide requested stack allocation compiler notes
+ provided in all cases (requested stack allocation not happening without a
+ note being issued is now considered a bug.)
+ * bug fix: on 64 bit platforms FILL worked incorrectly on arrays with
+ upgraded element type (COMPLEX SINGLE-FLOAT), regression from 1.0.28.55.
+ (thanks to Paul Khuong)
+ * bug fix: better error signalling when calls to functions seeking elements
+ from lists (eg. ADJOIN) are compiled with both :TEST and :TEST-NOT.
+ (reported by Tobias Rittweiler)

+changes in sbcl-1.0.29 relative to 1.0.28:
+ * IMPORTANT: bug database has moved from the BUGS file to Launchpad
+ https://bugs.launchpad.net/sbcl
+ Bugs can be reported directly there, or by sending email to
+ sbcl-bugs@lists.sourceforge.net
+ (no subscription required.)
* minor incompatible change: under weak type checking policy integer
types are weakened less aggressively.
* minor incompatible change: SAVE-LISP-AND-DIE :TOPLEVEL function is now
allowed to return, which causes SBCL to quit with exit status 0. Previously
if the function returned with a small integer return value, that value
was accidentally reused as the exit status.
+ * new feature: SB-EXT:DEFINE-HASH-TABLE-TEST allows defining new arguments
+ to MAKE-HASH-TABLE :TEST, and MAKE-HASH-TABLE has been extended with
+ :HASH-FUNCTION argument. Refer to user manual for details.
* new feature: SB-EXT:DEFGLOBAL macro allows defining global non-special
variables.
+ * new feature: SB-EXT:GET-TIME-OF-DAY provides access to seconds and
+ microseconds since the Unix epoch on all platforms.
* new feature: SB-EXT:ALWAYS-BOUND proclamation inhibits MAKUNBOUND, and
allows the compiler to safely elide boundedness checks for special
variables.
the symbol, prohibits both lexical and dynamic binding. This is mainly an
efficiency measure for threaded platforms, but also valueable in
expressing intent.
+ * new feature: UNC pathnames are now understood by the system on Windows.
+ * optimization: the compiler uses a specialized version of FILL when the
+ element type is know in more cases, making eg. (UNSIGNED-BYTE 8) case
+ almost 90% faster.
* optimization: accesses to potentially non-simple arrays where element type
is known are 50% faster.
* optimization: compiler now generates faster array typechecking code.
* improvement: pretty-printing loop has been implemented properly. (thanks
to Tobias Rittweiler)
* documentation: CLOS slot typechecing policy has been documented.
+ * bug fix: FILE-AUTHOR no longer signals an error on Windows.
+ * bug fix: SB-SPROF could be foiled by foreign code not have a frame
+ pointer, leading to memory faults. (thanks to Bart Botta)
* bug fix: better floating point exception handling on x86/OpenBSD.
(thanks to Josh Elsasser)
* bug fix: exit status from QUIT when called under --script was lost
* bug fix: signals delivered to threads started from foreign land (read:
directly by pthread_create, not by MAKE-THREAD) are redirected to a Lisp
thread by blocking all signals and resignalling.
+ * bug fix: SHARED-INITIALIZE initialized unbound :ALLOCATION :CLASS slots
+ from :INITFORM, if any.
changes in sbcl-1.0.28 relative to 1.0.27:
* a number of bugs in cross-compilation have been fixed, with the ultimate
