@@ -2173,14 +2173,93 @@ changes in sbcl-0.8.6 relative to sbcl-0.8.5:
     that the various BOOLE-related constants have the same value in
     host and target lisps.  (noted by Paul Dietz' test suite on an
     SBCL binary built from CLISP)
+  * The system can now be dynamically linked on the MIPS platform,
+    which enables dynamic loading of foreign code from Lisp.  (thanks
+    to Ralf Baechle for discussions on the MIPS ABI)
+  * The system now records debugging information for its own source
+    files in a filesystem-position-independent manner, relative to 
+    the "SYS" logical host.
   * fixed a compiler bug: MV-LET convertion did not check references
     to the "max args" entry point.  (reported by Brian Downing)
+  * tweaked disassembly notes to be less confident about proclaiming
+    some instruction as an LRA.  (thanks to Brian Downing)
+  * contrib update: SB-ACLREPL is now threadsafe; multiple listeners
+    now each have their own history, command character, and other
+    characteristics.  (thanks to David Lichteblau)
   * fixed some bugs revealed by Paul Dietz' test suite:
     ** compiler failure in compiling LOGAND expressions including a
-       constant 0.
-    ** implementation of ASH-MOD32 on X86 did not work for the shift
-       greater than 32.
+       constant 0
+    ** Implementation of ASH-MOD32 on X86 and PPC did not work for the
+       shift greater than 32.
     ** FLUSH-DEST did not mark blocks for type check regeneration.
+    ** HANDLER-CASE failed to accept declarations in handler clauses
+       in some circumstances.
+
+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
+       to cause DIVIDE-BY-ZERO or FLOATING-POINT-OVERFLOW errors.
+    ** extremely complex negations of CONS types were not being
+       sufficiently canonicalized, leading to inconsistencies in
+       SUBTYPEP.
+    ** VALUES tranformer lost derived type.
+
+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.
+    ** LOAD-LOGICAL-PATHNAME-TRANSLATIONS returns NIL if the logical
+       host is already defined.
+    ** RENAME-FILE works on streams instead of signalling an internal
+       type error.
+    ** PEEK-CHAR now uses the current readtable when determining
+       whether a character is whitespace.
