+changes in sbcl-1.0.22 relative to 1.0.21:
+ * 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)
+
+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.

changes in sbcl-1.0.20 relative to 1.0.19:
* minor incompatible change: OPTIMIZE qualities
SB-C::STACK-ALLOCATE-DYNAMIC-EXTENT, SB-C::STACK-ALLOCATE-VECTOR,
and SB-C::STACK-ALLOCATE-VALUE-CELLS no longer exist. See documentation
and SB-EXT:*STACK-ALLOCATE-DYNAMIC-EXTENT* for details.
+ * documentation: some slot access efficiency guidelines have been
+ added to the user manual.
* optimization: ASSOC-IF, ASSOC-IF-NOT, MEMBER-IF, MEMBER-IF-NOT,
RASSOC, RASSOC-IF, and RASSOC-IF-NOT are now equally efficient
as ASSOC and MEMEBER.
elided in more cases, eg: (let ((x 'foo)) (funcall foo)).
* optimization: compiler is able to derive the return type of
(AREF (THE STRING X) Y) as being CHARACTER.
+ * optimization: CLRHASH on empty hash-tables no longer does pointless
+ work. (thanks to Alec Berryman)
+ * optimization: REPLACE deftransforms don't punt when :START1 or
+ :START2 is given
+ * bug fix: compiling DESTRUCTURING-BIND on constant list arguments
+ no longer emits a code deletion note. (reported by Andrew
+ Gasparovic)
+ * bug fix: bogus odd-number-of-keywords STYLE-WARNINGs from calls to
+ functions with an odd number of &OPTIONAL arguments, a &REST
+ argument, and one or more &KEY arguments at the call site.
+ * bug fix: STYLE-WARNINGs for functions with both &OPTIONAL and &KEY
+ arguments appeared at call sites as well.
+ * bug fix: fixed #425; CLOSE drops input buffers from streams, so
+ READ-LINE &co can no longer read from them afterwards. (reported
+ by Damien Cassou)
* bug fix: fixed #427: unused local aliens no longer cause compiler
breakage. (reported by Stelian Ionescu, Andy Hefner and Stanislaw
Halik)
