+changes in sbcl-0.8.6 relative to sbcl-0.8.5:
+  * fixed a bootstrapping bug: the build process no longer assumes

+    host and target lisps.  (noted by Paul Dietz' test suite on an

+  * The system can now be dynamically linked on the MIPS platform,

+    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)

+changes in sbcl-0.8.7 relative to sbcl-0.8.6:
+  * When built with the :SB-FUTEX feature, threaded builds now take

+  * Incompatible change (but one you probably shouldn't have been using

+  * 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

+  * 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
