-  * improvement: SBCL now emits a compiler note where stack allocation was
-    requested but could not be provided.

   * optimization: compiler now generates faster array typechecking code.
   * optimization: ARRAY-DIMENSION is now faster for multidimensional and
     non-simple arrays.
   * optimization: multidimensional array accesses in the absence of type
     information regarding array rank are approximately 10% faster due to
     open coding of ARRAY-RANK.
