+ * optimization: result of (FILL (MAKE-ARRAY ...) ...) and (REPLACE
+ (MAKE-ARRAY ...) ...) can be stack allocated if the result of MAKE-ARRAY
+ form can be.
+ * optimization: result of call to VECTOR can now be stack allocated.
+ * optimization: MAKE-ARRAY with :INITIAL-CONTENTS is now vastly faster
+ as long as the resulting array is one-dimensional and has a known
+ element type. In particular, :INITIAL-CONTENTS (LIST ...) where the
+ length of the list matches the known length of the vector does not
+ allocate the list as an intermediate step. Ditto for VECTOR and simple
+ backquoted forms.
+ * optimization: MAKE-ARRAY can now stack allocate in the presence of
+ :INITIAL-CONTENTS and :INITIAL-ELEMENT as long as the result has a
+ known element type, and is known to be simple and one dimensional.
+ * improvement: SBCL now emits a compiler note where stack allocation was
+ requested but could not be provided (not in all cases, unfortunately)
+ * improvement: better MACHINE-VERSION responses. (thanks to Josh Elsasser)
+ * improvement: pretty-printing loop has been implemented properly. (thanks
+ to Tobias Rittweiler)
+ * documentation: CLOS slot typechecing policy has been documented.
+ * bug fix: FILE-AUTHOR no longer signals an error on Windows.
+ * bug fix: SB-SPROF could be foiled by foreign code not have a frame
+ pointer, leading to memory faults. (thanks to Bart Botta)
+ * bug fix: better floating point exception handling on x86/OpenBSD.
+ (thanks to Josh Elsasser)
+ * bug fix: exit status from QUIT when called under --script was lost
+ (reported by Hubert Kauker)
+ * bug fix: MAKE-ARRAY for non-zero :INITIAL-ELEMENT always used the
+ same implementation of FILL to initialize the array, even if a more
+ efficient one was available (reported by Stas Boukarev, thanks to
+ Paul Khuong)
+ * bug fix: potential miscompilation of array stack allocation on x86 and
+ x86-64. (reported by Time Tossavainen)
+ * bug fix: some forms of AND, OR, and COND resulted in expansions that could
+ result in their subforms being treated as top level forms. (reported by
+ James Knight)
+ * bug fix: On x86/x86-64 alien functions declared to return integers shorter
+ than a machine register could leave garbage in the high bits of the
+ result register (bug 316325).
