+changes relative to sbcl-1.1.8:
+  * enchancement: disassemble now annotates some previously missing static
+    functions, like LENGTH.
+  * optimization: calls to static functions on x86-64 use less instructions.
+  * optimization: compute encode-universal-time at compile time when possible.
+  * optimization: when referencing internal functions as #'x, don't go through
+    an indirect fdefn structure.
+  * optimization: SLEEP doesn't cons on non-immediate floats and on ratios.
+  * bug fix: problems with NCONC type derivation (reported by Jerry James).
+  * bug fix: EXPT type derivation no longer constructs bogus floating-point
+    types.  (reported by Vsevolod Dyomkin)
+  * bug fix: sb-bsd-sockets has correct declaration of the canonname field of
+    addrinfo. (lp#1187041, patch by Jerry James)

+changes in sbcl-1.1.8 relative to sbcl-1.1.7:
   * notice: The implementation of MAP-ALLOCATED-OBJECTS (the heart of
     ROOM, plus a few SB-INTROSPECT functions) has been completely
     rewritten; it may now exhibit different bugs than before.
+  * new feature: minimal runtime/compiler intrastructure support for SSE
+    SIMD values, as SB-EXT:SIMD-PACK. Enabled on x86-64 via the build-time
+    feature :sb-simd-pack. This should enable intrinsics extensions as
+    libraries, without patching SBCL itself. Thanks to Alexander Gavrilov
+    for maintaining a branch for so long.
   * enhancement: RUN-PROGRAM supports a :DIRECTORY argument to set
     the working directory of the spawned process.
