+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: division by zero in sb-sprof when no samples were collected
+ * bug fix: a race when a slow to arrive sigprof signal killed sbcl
+ * threads
+ ** 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
+
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-8859-3, iso-8859-4, iso-8859-5, iso-8859-6, iso-8859-7,
+ iso-8859-8, iso-8859-9, iso-8859-10, iso-8859-11, iso-8859-13,
+ 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.
* 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
+ 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
+ workaround will only be in effect on systems with the proc filesystem
+ mounted.
+ * 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
+ 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
+ ** bug fix: binding a special with PROGV to no value is not
+ the same as that symbol not having been bound (thanks to
+ Hannu Koivisto)
+ ** bug fix: binding specials is thread safe (thanks to
+ Hannu Koivisto)
+ ** bug fix: interrupt handlers are now per-process, RUN-PROGRAM
+ and SB-SPROF do not die with 'no handler for signal XX in
+ interrupt_handle_now(..)' anymore
+ ** bug fix: WITH-TIMEOUT works with multiple running threads
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** ENSURE-GENERIC-FUNCTION should take a method class object for
+ the :method-class keyword argument.
changes in sbcl-0.9.4 relative to sbcl-0.9.3:
* new port: the Solaris operating system on x86 processors is now
