+changes in sbcl-0.8.21 (0.9alpha.1?) relative to sbcl-0.8.20:
+  * incompatible change: thread support for non-NPTL systems has
+    been removed - locking is buggy and unreliable.  A threaded 
+    SBCL build will now refuse to start unless futex support is 
+    detected in the kernel
+  * 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*.
+  * built-in and standard functions no longer have names like "top
+    level local call to FOO".
+  * fixed bug 32: functions defined in non-null lexical environments
+    now have more legible printed representation
+  * fixed bug 33: functions defined in non-null lexical environemnts
+    are now more amenable to inspection by INSPECT.
+  * workaround for bug 354: XEPs no longer appear in backtraces unless
+    explicitly requested.
+  * fixed bug: receiving the signal which results from attempting to
+    write to mprotect()ed memory (SIGSEGV on Linux and some *BSDs,
+    SIGBUS on other *BSDs) on architectures where the C stack is also
+    the Lisp stack (x86 and x86-64) from foreign code no longer leads
+    to debugger confusion or wild instability.  (reported by Cheuksan
+    Wang)
+  * fixed bug: COUNT and EQUAL no longer issue compiler efficiency
+    notes when operating on objects known to be SIMPLE-BIT-VECTORs.
+    (reported by Lutz Euler)
+  * fixed bug: (TYPEP X '(MEMBER ...)) no longer returns a list in
+    compiled code. (reported by Paul Dietz)
+  * 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.
+  * fixed bug: the MAKE-INSTANCE optimization is now correct in the
+    face of package deletion.
+  * fixed bug: LOAD should bind *LOAD-PATHNAME* to the merged
+    pathname. (reported by David Tolpin on c.l.l)
+  * 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.
+  * contrib improvement: SB-INTROSPECT handles more of SLIME's needs
+    than previously; in addition, its test suite is now run on build.
+    (thanks to Luke Gorrie)
+  * a more robust x86-64 disassembler. (thanks to Lutz Euler)
+  * optimization: added a immediate representation for single-floats 
+    on x86-64
+  * fixed some bugs revealed by Paul Dietz' test suite:
+    ** MISC.564: defined out-of-line version of %ATAN2 on x86.
+    ** attempting to create a package with a colliding nickname causes
+       correctable errors to be signalled.
+    ** MISC.572-574: :START1 and :START2 broken for simple-base-strings.
+    ** several x86-64 backend bugs related to sign-extension of immediate
+       operands.

 changes in sbcl-0.8.20 (0.9alpha.0?) relative to sbcl-0.8.19:
+  * fixed inspection of specialized arrays. (thanks to Simon Alexander)
   * fixed disassembly of SHLD and SHRD on x86.  (thanks to David
     Lichteblau)
+  * fixed loading of multiply forward-referenced layouts. 
+    (thanks to Cheuksan Wang)
+  * fixed bug 7: less verbose COMPILE-FILE output. Additionally, the
+    output is now directed to *STANDARD-OUTPUT* as specified by ANSI. 
+    (see COMPILE-FILE documentation for details of :PRINT option)
   * fixed bugs 19 and 317: fixed-format floating point printing is
     more accurate.  This also fixes a bug reported by Adam Warner
     related to the ~@F format directive.
+  * fixed bug 371: bignum print/read inconsistency. (thanks to Harald
+    Hanche-Olsen)
   * fixed bug: SET-SYNTAX-FROM-CHAR correctly shallow-copies a
     dispatch table if the from-char is a dispatch macro character.
   * fixed bug: COUNT and EQUAL on bit vectors with lengths divisible
