+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
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.
changes in sbcl-1.0.20 relative to 1.0.19:
