   * 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.

     of quadratically with the size of the input in the worst case.
