 changes in sbcl-0.8.7 relative to sbcl-0.8.6:
+  * When built with the :SB-FUTEX feature, threaded builds now take 
+    advantage of the "fast userspace mutex" facility in Linux kernel 2.6
+    for faster/more reliable mutex and condition variable support.
+  * Incompatible change (but one you probably shouldn't have been using
+    anyway): the interface and code for arbitrating between multiple
+    threads in the same user session has been redesigned.
   * bug fix: GET-SETF-EXPANSION no longer throws an internal type
     error when called without an explicit environment argument.
     (thanks to Nikodemus Siivola)
   * bug fix: buffered :DIRECTION :IO streams are less likely to become
     confused about their position.  (thanks to Adam Warner and Gerd 
     Moellmann)
+  * bug fix: Pretty printing backquoted forms with unquotations in the
+    argument list position of various code constructs such as LAMBDA
+    now works correctly.  (reported by Paul Dietz)
+  * bug fix: Pretty printing unquotations no longer loses all
+    stream position information.
+  * optimization: performance of string output streams is now less
+    poor for multiple small sequence writes.
+  * optimization: performance of CSUBTYPEP in the presence of complex
+    expressions involving CONS and NOT many times has been improved.
+    (reported by Paul Dietz)
   * ASDF-INSTALL bug fix: now parses *PROXY* properly.  (thanks to
     Sean Ross)
+  * SB-SIMPLE-STREAMS enhancement: simple-streams can now be used as
+    streams for the REPL, for the debugger, and so on.  (thanks to
+    David Licteblau)
+  * DEFINE-CODITION is more efficient.  (thanks to Brian Mastenbrook)
   * fixed some bugs revealed by Paul Dietz' test suite:
     ** the value of the :REHASH-THRESHOLD argument to MAKE-HASH-TABLE
        is ignored if it is too small, rather than propagating through

     ** extremely complex negations of CONS types were not being

+changes in sbcl-0.8.8 relative to sbcl-0.8.7:
+  * bug fix: DECODE-UNIVERSAL-TIME now accepts timezone arguments with
+    second-resolution: integer multiples of 1/3600 between -24 and 24.
+    (thanks to Vincent Arkesteijn)
+  * optimization: implemented multiplication as a modular
+    (UNSIGNED-BYTE 32) operation on the x86 backend.
+  * optimization: SEARCH on simple-base-strings can now be open-coded.
+    (see also contrib/compiler-extras.lisp for inspiration for
+    teaching the compiler about the Boyer-Moore algorithm).
+  * bug fix: functions =, /=, <, <=, >, >= did not check the argument
+    type when called with 1 argument; PEEK-CHAR checked type of
+    PEEK-TYPE only after having read first character from a
+    stream. (reported by Peter Graves)
+  * fixed some bugs revealed by Paul Dietz' test suite:
+    ** in stack analysis liveness information is propagated from
+       non-local entry points.
+    ** pathwise CAST removing failed when the CAST node did not start
+       a block.
+    ** INPUT-STREAM-P, OUTPUT-STREAM-P, STREAM-ELEMENT-TYPE and
+       OPEN-STREAM-P signal a TYPE-ERROR if their argument is not a
+       stream.
