-  * optimization: compiler now generates faster typechecking code for
-    array dimensions.
+  * 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.
+  * 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.
 
 changes in sbcl-1.0.28 relative to 1.0.27:
   * a number of bugs in cross-compilation have been fixed, with the ultimate
