+changes in sbcl-1.0.22 relative to 1.0.21:
+  * minor incompatible change: LOAD-SHARED-OBJECT no longer by default looks
+    for the shared object in the current directory, but passes the native
+    namestring of the designated pathname to the operation system's shared
+    object loading function as-it.
+  * minor incompatible change: --disable-debugger toplevel option now takes
+    effect before processing of initialization files and --eval or --load
+    options.
+  * new feature: new commandline argument: --script, which supports
+    shebang lines. See documentation for details. (based on work by
+    Kevin Reid)
+  * new feature: SAVE-LISP-AND-DIE can save current values of
+    --dynamic-space-size and --control-stack-size in the executable core,
+    causing it to skip normal runtime option processing. See documentation
+    for details. (thanks to Zach Beane)
+  * enhancement: inoccous calls to EVAL or generic functions dispatching
+    on subclasses of eg. STREAM no longer cause compiler notes to appear.
+  * enhancement: the system no longer resignals errors from --load and
+    --eval toplevel arguments as SIMPLE-ERRORS, which caused restarts
+    associated with the original error to be lost. (thanks to Ariel
+    Badichi)
+  * enhancement: :DONT-SAVE keyword argument has been added to
+    LOAD-SHARED-OBJECT for controlling interaction with
+    SAVE-LISP-AND-DIE.
+  * bug fix: ADJUST-ARRAY on multidimensional arrays used bogusly give
+    them a fill pointer unless :DISPLACED-TO or :INITIAL-CONTENTS were
+    provided. (reported by Cedric St-Jean)
+  * bug fix: circularity handling in the reader did not treat raw
+    structure slots correctly. (reported by Cedric St-Jean)
+  * bug fix: SERVE-EVENT occasionally signaled an error about bogus
+    file descriptors when there were none.
+  * bug fix: DEFINE-COMPILER-MACRO support of destructuring lambda-lists
+    was broken. (reporteed by Willem Broekema)
+  * bug fix: SB-EXT:NATIVE-NAMESTRING on Windows did not work on
+    pathnames without a directory.
+  * bug fix: COMPILE-FILE did not warn about undefined variable
+    references at toplevel, and LOAD of the resulting fasl did
+    not signal an error.
+
+changes in sbcl-1.0.21 relative to 1.0.20:
+  * new feature: the compiler is able to track the effective type of a
+    generic function across method addition and removal.
+  * new feature: SB-EXT:ATOMIC-INCF allows atomic incrementation of
+    appropriately typed structure slots without locking.
+  * new feature: SB-EXT:CALL-WITH-TIMING provides access to timing
+    information like those gathered by TIME using a programming-friendly
+    interface.
+  * new feature: TIME reports time taken even if the form performs a
+    non-local transfer of control.
+  * enhancement: reduced conservativism on GENCGC platforms: on
+    average 45% less pages pinned (measured from SBCL self build).
+  * bug fix: SB-EXT:COMPARE-AND-SWAP on SYMBOL-VALUE can no longer
+    mutate constant symbols or violate declaimed type of the symbol.
+  * bug fix: SB-THREAD:SIGNAL-SEMAPHORE could fail to wakeup threads
+    sleeping on the semaphore in heavily contested semaphores.
+  * bug fix: semaphores and condition variables were not interrupt
+    safe.
+  * bug fix: SB-THREAD:CONDITION-WAIT doesn't allow waits on mutexes
+    owned by other threads anymore.
+  * bug fix: FIND on lists called KEY outside the specified
+    subsequence. (reported by budden)
+  * bug fix: LOG doesn't use single-float intermediate results when
+    given mixed integer and double-float arguments, leading to better
+    precision. (reported by Bob Felts)
+  * bug fix: LOG with base zero returned values of inconsistent type.
