+ * bug fix: SB-EXT:MUFFLE-CONDITIONS declarations no longer trigger a
+ bogus warning in DEFMETHOD bodies. (reported by Kevin Reid)
+ * bug fix: an &environment argument with the correct variable information
+ is passed to macros that are expanded during byte compilation.
+ (reported by Samium Gromoff)
+ * bug fix: a logic error was causing the hash function for bignums to
+ have excessive amounts of collisions. (reported by Faré Rideau)
+ * bug fix: modifying the contents of an array could change the return
+ value of SXHASH on that array, which is only allowed for strings
+ and bit vectors. (bug introduced in 0.9.16)
+ * improvement: the x86-64/darwin port now passes all tests (except
+ for the debugger tests) but should still be considered
+ experimental until this is fixed.
+ * improvement: a style-warning is signaled for CASE (etc) clauses with
+ duplicate keys. (thanks to Kevin Reid)
+ * improvement: macos/x86 and macos/x86-64 now use mach exception
+ handlers for dealing with illegal instructions (for trapping and
+ error handling) and memory protection violations (for GC).
