+ :METACLASS argument in addition to a class name. (reported by
+ Bruno Haible for CMUCL, patch for CMUCL by Gerd Moellmann)
+ * RESTART-CASE can now be wrapped around CALL-METHOD forms.
+ (reported by Bruno Haible; patch from Gerd Moellmann)
+ * bug fix: sbcl runtime can now be compiled with gcc4 (thanks to
+ Sascha Wilde)
+ * 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, and PPC platforms.
+ * contrib improvement: it's harder to cause SOCKET-CLOSE to close()
+ the wrong file descriptor; implementation of SOCKET-OPEN-P.
+ (thanks to Tony Martinez)
+ * threads
+ ** gcing a dead thread can no longer lead to lockups
+ ** threads block signals until they are set up properly
+ ** errno is no longer shared by threads
+ ** interrupt-thread restores the eflags register on x86
+ ** fixed some lockups due to gc/thread interaction
