+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-8859-14, 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.
+ * 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
+ mostly supported, though some rough edges in the environment
+ remain. (thanks to Daisuke Homma)

+ closures. (thanks to Thiemo Seufer)

+ is disabled.
+ * minor incompatible change: SB-KERNEL:INSTANCE-LAMBDA is
+ deprecated, and will go away in a future revision of SBCL.
+ * minor incompatible change: GC-ON and GC-OFF are no longer
+ implemented with a counter, it does not matter how many times gc
+ is switched on or off
+ * bug fix: discriminating functions for generic function classes
+ with non-standard methods for COMPUTE-APPLICABLE-METHODS no longer
+ make invalid assumptions about method precedence order. (reported
+ by Bruno Haible)

+ (thanks to Kevin Reid)
+ * bug fix: complex VOP definitions in "user-space" no longer trigger
+ package locks. (reported by Zach Beane)
+ * fixed bug 343: SB-KERNEL:INSTANCE-LAMBDA is no longer necessary
+ for funcallable-instance functions, and is no different from
+ regular LAMBDA.
+ * bug fix: PARSE-INTEGER no longer depends on the whitespaceness of
+ characters in the current readtable. (reported by Nicholas Neuss)
+ * bug fix: SUBTYPEP on various CONS types returns more a more
+ accurate acknowledgment of its certainty.
+ * optimizations: REMOVE-DUPLICATES now runs in linear time on
+ lists in some cases. This partially fixes bug 384.
+ * flush all standard streams before prompting in the REPL and the
+ debugger.

+ directly anymore, in particular a high frequency sb-sprof does
+ not prevent gc from running

+ approximation for timezone and DST information between the
+ universal time epoch and the smallest negative 32-bit time_t.
+ * bug fix: ENCODE-UNIVERSAL-TIME no longer errors when passed the
+ year 1899 so long as the encoded time is non-negative.

+ the correct answer for non-constant rotate amounts when performing
+ an inline 32-bit rotation.

+ there is only one thread in the session
+ ** bug fix: memory leak for streams created in one thread and
+ written to in another

+ ** bug fix: race that allows the gc to be triggered when gc is
+ inhibited
+ ** bug fix: one less memory fault in INTERRUPT-THREAD, again
+ ** bug fix: gc and INTERRUPT-THREAD don't hang when the RT signal
+ queue is full
+ ** bug fix: finished threads are gc'ed properly
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** CALL-NEXT-METHOD signals an error (in safe code) when the call
+ has arguments with a different set of applicable methods from
+ the orignal arguments.
+ ** The type error thrown by MAP now has a correct expected-type
+ cell.
+ ** DISASSEMBLE now throws a TYPE-ERROR when its argument does not
+ name a compiled function.
+ ** Three MISC tests where a large bignum was improperly coerced to
+ a float that couldn't represent that bignum during type
+ derivation were fixed.
+ ** SUBTYPEP can now handle types involving the negation of a
+ list-form FUNCTION type.
+ ** SUBTYPEP also now handles certain COMPLEX type specifiers such
+ as (COMPLEX (AND RATIO (NOT FIXNUM))).
+ ** READ-BYTE and WRITE-BYTE no longer take stream designators.
+
+changes in sbcl-0.9.3 relative to sbcl-0.9.2:

+ (unsigned-byte 8) I/O

+ readable" when reading a stream and an interrupt hits in the middle
+ of a select system call
+ * compiler better recognizes complex arrays (reported by Eduardo
+ Muñoz)
+ * bug fix: out-of-line SB-SYS:FOREIGN-SYMBOL-ADDRESS did not work

+ code and foreign data with the same name.
+ * threads
+ ** added x86-64 support
+ ** incompatible change: the threading api now works with thread
+ objects instead of thread ids
+ ** bug fix: threads are protected from signals and interruption when
+ starting up or going down
+ ** bug fix: a race where an exiting thread could lose its stack to gc
+ ** bug fix: don't halt on infinite error in threads if possible
+ ** fixed numerous gc deadlocks introduced in the pthread merge

+ * numerous signal handling fixes to increase stability
+ * Support for EUC-JP external format. (thanks to NIIMI Satoshi)

+ are treated as requests for stack allocation on the x86-64,
+ Alpha-32, PPC and SPARC platforms.
* contrib improvement: it's harder to cause SOCKET-CLOSE to close()
- the wrong file descriptor. (thanks to Tony Martinez)
+ the wrong file descriptor; implementation of SOCKET-OPEN-P.
+ (thanks to Tony Martinez)
