+ * minor incompatible change: SAVE-LISP-AND-DIE :TOPLEVEL function is now
+ allowed to return, which causes SBCL to quit with exit status 0. Previously
+ if the function returned with a small integer return value, that value
+ was accidentally reused as the exit status.
+ * new feature: SB-EXT:DEFGLOBAL macro allows defining global non-special
+ variables.
+ * new feature: SB-EXT:ALWAYS-BOUND proclamation inhibits MAKUNBOUND, and
+ allows the compiler to safely elide boundedness checks for special
+ variables.
+ * new feature: SB-EXT:GLOBAL proclamation inhibits SPECIAL proclamations for
+ the symbol, prohibits both lexical and dynamic binding. This is mainly an
+ efficiency measure for threaded platforms, but also valueable in
+ expressing intent.
* optimization: compiler now generates faster array typechecking code.
* optimization: ARRAY-DIMENSION is now faster for multidimensional and
non-simple arrays.
* optimization: multidimensional array accesses in the absence of type
information regarding array rank are approximately 10% faster due to
open coding of ARRAY-RANK.
+ * improvement: SBCL now emits a compiler note where stack allocation was
+ requested but could not be provided.
+ * 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: 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

* bug fix: the value of CL:- in the inspector was the previous expression
evaluated rather than the expression being evaluated.
+ * bug fix: constants can no longer be locally declared special.
+ * bug fix: signals delivered to threads started from foreign land (read:
+ directly by pthread_create, not by MAKE-THREAD) are redirected to a Lisp
+ thread by blocking all signals and resignalling.
changes in sbcl-1.0.28 relative to 1.0.27:
