+changes in sbcl-0.8.22 relative to sbcl-0.8.21:
+  * incompatible change: the --noprogrammer option, deprecated since
+    version 0.7.5, has been removed.  Please use the equivalent
+    --disable-debugger option instead.
+  * optimization: REPLACE on declared (UNSIGNED-BYTE 8) vectors, as well
+    as other specialized array types, is much faster.  SUBSEQ and
+    COPY-SEQ on such arrays have also been sped up.
+  * fixed inference of the upper bound of an iteration variable.
+    (reported by Rajat Datta).
+  * fixed bug 376: CONJUGATE type deriver.
+  * fixed some bugs revealed by Paul Dietz' test suite:
+    ** MISC.549 and similar: late transformation of unsafe type
+       assertions into derived types caused unexpected code
+       transformations.
+    ** SCALE-FLOAT type deriver is less wrong.
+    ** type derivers for EXP, LOG and similar functions compute result
+       types for complex arguments better.
+    ** (MISC.563) CONJUGATE type deriver works for very restricted
+       complex types.
+    ** out-of-line type testers for character strings are available.
+    ** EQUAL compiler transform understands specialness of objects
+       of type BIT-VECTOR.

 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 warn at startup and refuse to create
+    new threads, 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.
+  * The .fasl file format number has been incremented because of 
+    various incompatible changes.
   * internal entry point details and argument counts no longer appear
-     in backtraces unless explicitly requested by setting
-     SB-DEBUG:*SHOW-ENTRY-POINT-DETAILS*.
+    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".
+    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.
+    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)
