+changes in sbcl-0.9.7 relative to sbcl-0.9.6:
+  * minor incompatible change: (SETF CLASS-NAME) and (SETF
+    GENERIC-FUNCTION-NAME) are no longer generic functions, and
+    therefore are not customizeable by user code (as seems to be at
+    least permitted and maybe required by AMOP).  As a consolation,
+    however, the SBCL implementation of these functions now calls
+    REINITIALIZE-INSTANCE as specified by AMOP.
+  * bug fix: REINITIALIZE-INSTANCE on generic functions calls
+    COMPUTE-DISCRIMINATING-FUNCTION (almost) unconditionally, as
+    specified by AMOP.
+  * bug fix: it is now possible to have more than one subclass of
+    STANDARD-GENERIC-FUNCTION without causing stack overflow.
+    (reported by Bruno Haible, Pascal Costanza and others)
+  * bug fix: the dependent update protocol now works for generic
+    functions.  (thanks to Gerd Moellmann; reported by Bruno Haible
+    and Pascal Costanza)
+  * bug fix: *COMPILE-FILE-PATHNAME* now contains the user's pathname
+    merged with *DEFAULT-PATHNAME-DEFAULTS*.
+  * enhancement: the x86-64 disassembler is much better at
+    disassembling SSE instructions.  (thanks to Lutz Euler)
+  * optimization: improved performance of EUC-JP external format.
+    (thanks to NIIMI Satoshi)
+  * optimization: performance improvements to IO on file streams of
+    :ELEMENT-TYPE CHARACTER
+  * optimization: much faster memory allocation on x86-64
+  * optimization: faster garbage collections (latency and throughput)
+    on gencgc

+  * bug fix: Unicode symbols are correctly printed in LDB backtraces
+    (thanks to David Lichteblau)
+  * bug fix: local bindings shadow global symbol macros for
+    macroexpansion.  (reported by Matthew D Swank on comp.lang.lisp)
+  * optimization: non-open coded uses of numeric comparison operators
+    (e.g. >) no longer cons when called with more than one parameter
+    on platforms supporting dynamic-extent allocation.
+  * enhancement: saving cores with foreign code loaded is now supported
+    on MIPS/Linux in addition to the previously supported platforms.
+  * bug fix: FIND-RESTART now tests for activity, not applicability when given
+    a restart object as identifier. (reported by Helmut Eller for CMUCL)
+  * bug fix: division by zero in sb-sprof when no samples were collected
+  * bug fix: a race when a slow to arrive sigprof signal killed sbcl
+  * bug fix: asdf-install uses CRLF as required by the HTTP spec.
+    (thanks to Alexander Kjeldaas)
+  * new feature: ignoring the return values of destructive functions
+    like NREVERSE signals a compile-time style-warning.
+    (thanks to Kevin Reid)
+  * new feature: the alignment of alien structure fields can be
+    explicitly specified. (thanks to Cyrus Harmon)
+  * bug fix: run cleanup forms (in all threads) when receiving a SIGTERM
+    and dump core on SIGQUIT
+  * threads
+    ** incompatible change: threads do not inherit values of specials
+       from their parents (see manual)
+    ** bug fix: threads stacks belonging to dead threads are freed by the
+       next exiting thread, no need to gc to collect thread stacks anymore
+    ** minor incompatible change: INTERRUPT-THREAD-ERROR-ERRNO removed
+    ** WITH-RECURSIVE-LOCK can be nested in a WITH-MUTEX for the same lock
+    ** bug fix: dynamic variable and thread start related gc lossage
+    ** bug fix: job control (SIGSTOP/SIGCONT) no longer confuses threads
+       suspended for gc
+  * fixed some bugs revealed by Paul Dietz' test suite:
+    ** SUBTYPEP is slightly more accurate on heinously complicated
+       CONS types where some of the members have uncertain (in the
+       NIL, NIL sense) type relationships to each other.
+  * GENCGC
+    ** Cores produced by SAVE-LISP-AND-DIE on GENCGC platforms are
+       no longer purified unless :PURIFY T is explicitly specified.
+    ** Non-purified cores are significantly smaller than before
