+ * 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.
+ * bug fix: potential miscompilation of array stack allocation on x86 and
+ x86-64. (reported by Time Tossavainen)
+ * bug fix: some forms of AND, OR, and COND resulted in expansions that could
+ result in their subforms being treated as top level forms. (reported by
+ James Knight)
