+ * minor incompatible change: under weak type checking policy integer
+ types are weakened less aggressively.
+ * 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:DEFINE-HASH-TABLE-TEST allows defining new arguments
+ to MAKE-HASH-TABLE :TEST, and MAKE-HASH-TABLE has been extended with
+ :HASH-FUNCTION argument. Refer to user manual for details.
+ * new feature: SB-EXT:DEFGLOBAL macro allows defining global non-special
+ variables.
+ * new feature: SB-EXT:GET-TIME-OF-DAY provides access to seconds and
+ microseconds since the Unix epoch on all platforms.
+ * 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.
+ * new feature: UNC pathnames are now understood by the system on Windows.
+ * optimization: the compiler uses a specialized version of FILL when the
+ element type is know in more cases, making eg. (UNSIGNED-BYTE 8) case
+ almost 90% faster.
+ * optimization: accesses to potentially non-simple arrays where element type
+ is known are 50% faster.
+ * optimization: compiler now generates faster array typechecking code.
+ * optimization: ARRAY-DIMENSION is now faster for multidimensional and
+ non-simple arrays.
