+changes in sbcl-0.9.3 relative to sbcl-0.9.2:
+  * New feature: Experimental support for bivalent streams: streams
+    opened with :element-type :default now allow character and binary
+    (unsigned-byte 8) I/O
+  * Support for the koi8-r external format.  (thanks to Ivan Boldyrev)
+  * Bug fix: OPEN no longer fails when *PRINT-READABLY* is T. (thanks
+    to Zach Beane)
+  * bug fix: no more highly sporadic "couldn't check whether ~S is
+    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
+    for variables on SBCL built with linkage-tables. (reported by Luis
+    Oliveira)
+  * various error reporting improvements.
+  * optimizations: LOGNOR on fixnums is improved in the MIPS backend.
+    (Thanks to Thiemo Seufer)
+  * bug fix: nested reader invokations work correctly
+  * 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
+    ** bug fix: fixed thread safety issues in read and print
+    ** bug fix: debugger doesn't hang on session lock if interrupted at
+       an inappropriate moment
+    ** bug fix: run-program is now thread safe(r)
+  * fixed some bugs revealed by Paul Dietz' test suite:
+    ** TYPE-ERRORs from signalled by COERCE now have DATUM and
+       EXPECTED-TYPE slots filled.
+    ** MULTIPLE-VALUE-SETQ always returns the primary value of the
+       values form.
+    ** MAKE-CONDITION accepts classes as type-designators.
+    ** COMPILE may never return NIL.

 changes in sbcl-0.9.2 relative to sbcl-0.9.1:
+  * numerous signal handling fixes to increase stability
+  * Support for EUC-JP external format.  (thanks to NIIMI Satoshi)
   * minor incompatible change: we now correctly canonize default
     initargs, making them be a list of (INITARG INITFORM INITFUNCTION)
     as per the MOP, rather than the historical (INITARG INITFUNCTION

   * TRUENAME and PROBE-FILE now correctly resolve symlinks even if the

   * SB-SPROF now works (more) reliably on non-GENCGC platforms.
-  * fixed some lockups due to gc/thread interaction
   * dynamic space size on PPC has been increased to 768Mb. (thanks to

   * SB-MOP:ENSURE-CLASS-USING-CLASS now accepts a class as the

   * bug fix: sbcl runtime can now be compiled with gcc4 (thanks to

   * bug fix: more cleanups to the floating point exception handling on
     x86-64 (thanks to James Knight)
+  * bug fix: the compiler does not try to constant fold calls of
+    COERCE and BIT-* functions when they return freshly constructed
+    objects. (reported by Nikodemus Siivola and Paul Dietz)
   * optimization: improved the MIPS versions of generic (in the
     generic sense) arithmetic routines.  (thanks to Thiemo Seufer)
+  * optimization: direct conversion of (unsigned-byte 32) to floats on
+    the PowerPC platform.
+  * optimization: structure instances with raw slots now use less
+    memory, and probably show better memory locality.  (thanks to
+    David Lichteblau)
+  * optimization: DYNAMIC-EXTENT declarations for lists and closures
+    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; implementation of SOCKET-OPEN-P.

+    ** gcing a dead thread can no longer lead to lockups
