+changes in sbcl-0.8.22 relative to sbcl-0.8.21:
+ * incompatible change: the --noprogrammer option, deprecated since
+ version 0.7.5, has been removed. Please use the equivalent
+ --disable-debugger option instead.
+ * optimization: REPLACE on declared (UNSIGNED-BYTE 8) vectors, as well
+ as other specialized array types, is much faster. SUBSEQ and
+ COPY-SEQ on such arrays have also been sped up.
+ * fixed inference of the upper bound of an iteration variable.
+ (reported by Rajat Datta).
+ * fixed bug 376: CONJUGATE type deriver.
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** MISC.549 and similar: late transformation of unsafe type
+ assertions into derived types caused unexpected code
+ transformations.
+ ** SCALE-FLOAT type deriver is less wrong.
+ ** type derivers for EXP, LOG and similar functions compute result
+ types for complex arguments better.
+ ** (MISC.563) CONJUGATE type deriver works for very restricted
+ complex types.
+ ** out-of-line type testers for character strings are available.
+ ** EQUAL compiler transform understands specialness of objects
+ of type BIT-VECTOR.
