+  * 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.
+  * improvement: SBCL now emits a compiler note where stack allocation was
+    requested but could not be provided.
+  * 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.
+  * documentation: CLOS slot typechecing policy has been documented.
+  * 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).
+  * bug fix: disable address space randomization Linux/x86-64 as well,
+    not just x86-64. (reported by Ken Olum)
+  * bug fix: Attempting to DEREF an (ALIEN (* T)) would produce a WARNING and
+    generate incorrect code.
+  * bug fix: #201; type inference for CONS and ARRAY types could derive
+    wrong results in the presence of eg. RPLACA or ADJUST-ARRAY.
+  * bug fix: special variables with a proclaimed specific subtype of FUNCTION
+    could not be assigned to or bound with PROGV. (reported by Lorenz
+    Mösenlechner)
+  * 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:
+  * a number of bugs in cross-compilation have been fixed, with the ultimate
+    result that building under (at least) clisp should be much more reliable.
   * minor incompatible changes: echo-streams now propagate unread-char to the
     underlying input stream, and no longer permit unreading more than one
     character.

   * bug fix: RESTART-FRAME and RETURN-FROM-FRAME stack corruption
   * bug fix: the discriminating function for PRINT-OBJECT no longer preserves
