+ * 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)
+ * bug fix: disable address space randomization Linux/x86-64 as well,
+ not just x86-64. (reported by Ken Olum)
+ * bug fix: #201; type inference for CONS and ARRAY types could derive
+ wrong results in the presence of eg. RPLACA or ADJUST-ARRAY.
+ * bug fix: special variables with a proclaimed specific subtype of FUNCTION
+ could not be assigned to or bound with PROGV. (reported by Lorenz
+ Mösenlechner)

changes in sbcl-1.0.28 relative to 1.0.27:
+ * a number of bugs in cross-compilation have been fixed, with the ultimate
+ result that building under (at least) clisp should be much more reliable.
* minor incompatible changes: echo-streams now propagate unread-char to the
underlying input stream, and no longer permit unreading more than one
character.
potentially-invalid effective methods in its cache.
* bug fix: SB-INTROSPECT:FIND-DEFINITION-SOURCE now works with funcallable
instances as well (thanks to Paul Khuong)
+ * bug fix: using RUN-PROGRAM does not interfere with SB-POSIX:WAIT,
+ SB-POSIX:WAITPID and their C equivalents.
+ * bug fix: RUN-PROGRAM does not crash on Darwin when stressed.
changes in sbcl-1.0.27 relative to 1.0.26:
* new port: support added for x86-64 OpenBSD. (thanks to Josh Elsasser)
