+changes in sbcl-0.9.7 relative to sbcl-0.9.6:
+ * minor incompatible change: (SETF CLASS-NAME) and (SETF
+ GENERIC-FUNCTION-NAME) are no longer generic functions, and
+ therefore are not customizeable by user code (as seems to be at
+ least permitted and maybe required by AMOP). As a consolation,
+ however, the SBCL implementation of these functions now calls
+ REINITIALIZE-INSTANCE as specified by AMOP.
+ * bug fix: slot-definition documentation is propagated as per ANSI
+ 7.6.2 to EFFECTIVE-SLOT-DEFINITIONS.
+ COMPUTE-EFFECTIVE-SLOT-DEFINITION now receives a :DOCUMENTATION
+ argument, as do eslotd initialization methods. (from Pascal
+ Costanza's "Closer" project)
+ * bug fix: REINITIALIZE-INSTANCE on generic functions calls
+ COMPUTE-DISCRIMINATING-FUNCTION (almost) unconditionally, as
+ specified by AMOP.
+ * bug fix: it is now possible to have more than one subclass of
+ STANDARD-GENERIC-FUNCTION without causing stack overflow.
+ (reported by Bruno Haible, Pascal Costanza and others)
+ * bug fix: the dependent update protocol now works for generic
+ functions. (thanks to Gerd Moellmann; reported by Bruno Haible
+ and Pascal Costanza)
+ * bug fix: *COMPILE-FILE-PATHNAME* now contains the user's pathname
+ merged with *DEFAULT-PATHNAME-DEFAULTS*.
+ * bug fix: callbacks on OS X now preserve stack-alignment.
+ (thanks to Cyrus Harmon)
+ * enhancement: the x86-64 disassembler is much better at
+ disassembling SSE instructions. (thanks to Lutz Euler)
+ * enhancement: CHECK-TYPE on a variable now allows type-inference
+ (thanks to Vincent Arkesteijn)
+ * optimization: improved performance of EUC-JP external format.
+ (thanks to NIIMI Satoshi)
+ * optimization: performance improvements to IO on file streams of
+ :ELEMENT-TYPE CHARACTER
+ * optimization: much faster memory allocation on x86-64
+ * optimization: faster garbage collections (latency and throughput)
+ on gencgc
+ * optimization: faster bignum subtraction and division on x86 and x86-64
+ (thanks to Lutz Euler)
+
+changes in sbcl-0.9.6 relative to sbcl-0.9.5:
+ * bug fix: add a workaround to SBCL looping infinitely at startup on
+ Linux kernels with apparently buggy implementations of personality().
+ (thanks to Svein Ove Aas)
+ * bug fix: Unicode symbols are correctly printed in LDB backtraces
+ (thanks to David Lichteblau)
+ * bug fix: local bindings shadow global symbol macros for
+ macroexpansion. (reported by Matthew D Swank on comp.lang.lisp)
+ * optimization: non-open coded uses of numeric comparison operators
+ (e.g. >) no longer cons when called with more than one parameter
+ on platforms supporting dynamic-extent allocation.
+ * enhancement: saving cores with foreign code loaded is now supported
+ on MIPS/Linux in addition to the previously supported platforms.
+ * bug fix: FIND-RESTART now tests for activity, not applicability when given
+ a restart object as identifier. (reported by Helmut Eller for CMUCL)
+ * bug fix: division by zero in sb-sprof when no samples were collected
+ * bug fix: a race when a slow to arrive sigprof signal killed sbcl
+ * bug fix: asdf-install uses CRLF as required by the HTTP spec.
+ (thanks to Alexander Kjeldaas)
+ * new feature: ignoring the return values of destructive functions
+ like NREVERSE signals a compile-time style-warning.
+ (thanks to Kevin Reid)
+ * new feature: the alignment of alien structure fields can be
+ explicitly specified. (thanks to Cyrus Harmon)
+ * bug fix: run cleanup forms (in all threads) when receiving a SIGTERM
+ and dump core on SIGQUIT
+ * threads
+ ** incompatible change: threads do not inherit values of specials
+ from their parents (see manual)
+ ** bug fix: threads stacks belonging to dead threads are freed by the
+ next exiting thread, no need to gc to collect thread stacks anymore
+ ** minor incompatible change: INTERRUPT-THREAD-ERROR-ERRNO removed
+ ** WITH-RECURSIVE-LOCK can be nested in a WITH-MUTEX for the same lock
+ ** bug fix: dynamic variable and thread start related gc lossage
+ ** bug fix: job control (SIGSTOP/SIGCONT) no longer confuses threads
+ suspended for gc
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** SUBTYPEP is slightly more accurate on heinously complicated
+ CONS types where some of the members have uncertain (in the
+ NIL, NIL sense) type relationships to each other.
+ * GENCGC
+ ** Cores produced by SAVE-LISP-AND-DIE on GENCGC platforms are
+ no longer purified unless :PURIFY T is explicitly specified.
+ ** Non-purified cores are significantly smaller than before
+
changes in sbcl-0.9.5 relative to sbcl-0.9.4:
+ * new feature: timers based on Zach Beane's excellent timer package
* added support for the following external formats: koi8-u,
x-mac-cyrillic, cp437, cp850, cp852, cp855, cp857, cp860, cp861,
cp862, cp863, cp864, cp865, cp866, cp869, cp874, iso-8859-2,

iso-8859-14, cp1250, cp1251, cp1252, cp1253, cp1254,
cp1255,cp1256, cp1257, cp1258 (contributed by Ivan Boldyrev)
- * incompatible change: a threaded SBCL will no longer revert to
- non-threaded mode on non-NPTL systems, but refuse to start entirely.
+ * incompatible change: a threaded SBCL will no longer revert to
+ non-threaded mode on non-NPTL systems, but refuse to start entirely.
* bug fix: interrupts are disabled until startup is complete; no
more sigsegvs when receiving a signal to soon
- * optimization: Faster 32-bit SB-ROTATE-BYTE:ROTATE-BYTE on non-x86/ppc
+ * optimization: faster 32-bit SB-ROTATE-BYTE:ROTATE-BYTE on non-x86/ppc
platforms
* bug fix: add a workaround for the memory randomization features in
Linux kernels >= 2.6.12 that interfere with SBCL's memory maps. This
* bug fix: printing objects of type HASH-TABLE signals a
PRINT-NOT-READABLE error when *READ-EVAL* is NIL. (reported by
Faré Rideau)
- * bug fix: GET-INTERNAL-REAL-TIME now works even for processes that
+ * bug fix: GET-INTERNAL-REAL-TIME now works even for processes that
have been running for over 50 days. (reported by Gilbert Baumann)
* bug fix: the logic for getting names of functions gets less
confused when confronded with alternate-metaclass
funcallable-instances. (reported by Cyrus Harmon)
+ * bug fix: FUNCTIONP and (LAMBDA (X) (TYPEP X 'FUNCTION)) are now
+ consistent, even on internal alternate-metaclass objects.
+ * bug fix: flush closure information collected by physical
+ environment analysis prepass before the main pass. (bug reported
+ by Vasile Rotaru)
+ * bug fix: compiler pack phase does not modify a hashtable, which is
+ iterated. (reported by Bryan O'Connor, fixed by Rob MacLachlan)
+ * bug fix: backquote does not optimize (LIST* x y) to CONS when x
+ may be expanded. (reported by Alexander <malishev> on c.l.l)
+ * bug fix: no more style-warnings when compiling code using LAST
+ under high-SPEED low-SPACE settings. (reported by David Wallin
+ aka froog on #lisp)
+ * fixed some incompatibilities between SBCL's MOP and the MOP
+ specified by AMOP:
+ ** the METAOBJECT class is now implemented;
+ ** FUNCALLABLE-STANDARD-OBJECT is now a subclass of
+ STANDARD-OBJECT, as required;
+ ** the classes STANDARD-CLASS and FUNCALLABLE-STANDARD-CLASS are
+ now compatible (as required by VALIDATE-SUPERCLASS); there
+ remains a consistency requirement over the presence or absence
+ of the FUNCTION class in the superclass list of finalized
+ classes; see the manual for more details;
+ ** the :AROUND method for COMPUTE-SLOTS on
+ FUNCALLABLE-STANDARD-CLASS now honours the primary method's
+ requested slot ordering.
* threads
** bug fix: parent thread now can be gc'ed even with a live
child thread
(thanks to Richard Kreuter)
* bug fix: defining classes whose accessors are methods on existing
generic functions in other (locked) packages no longer signals
- bogus package lock violations. (reported by François-René Rideau)
+ bogus package lock violations. (reported by François-René Rideau)
* bug fix: special variables as DEFMETHOD parameters no longer have
associated bogus type declarations. (reported by David Wragg and
Bruno Haible)
