 changes in sbcl-0.8.21 (0.9alpha.1?) relative to sbcl-0.8.20:
+  * incompatible change: the top level REPL now has only an ABORT
+    restart associated with it, not TOPLEVEL and ABORT as it used to.
+    TOP and TOPLEVEL are now available as debugger commands for 
+    returning to the top level.
+  * incompatible change: forms evaluated in the REPL now use the
+    global optimization policy.
+  * incompatible change: user- and system-initialization files are
+    no longer processed with LOAD, but by READ and EVAL; hence the
+    global optimization policy, startup package, readtable, etc, 
+    can be set by them.
   * internal entry point details and argument counts no longer appear
-     in backtraces unless explicitly requested by setting
-     SB-DEBUG:*SHOW-ENTRY-POINT-DETAILS*.

   * fixed bug 276b: mutating with MULTIPLE-VALUE-SETQ a binding of a
     specialized parameter to a method to something that is not TYPEP
     the specializer is now possible.

   * contrib improvement: the SB-SIMPLE-STREAMS contrib now defines
     STRING-SIMPLE-STREAM and FILE-SIMPLE-STREAM as subclasses of
     STRING-STREAM and FILE-STREAM, respectively.

+  * a more robust x86-64 disassembler. (thanks to Lutz Euler)
+  * optimization: added a immediate representation for single-floats

   * fixed some bugs revealed by Paul Dietz' test suite:
     ** MISC.564: defined out-of-line version of %ATAN2 on x86.
