* enhancement: on 64-bit targets, in src/compiler/generic/early-vm.lisp,
the parameter n-fixnum-tag-bits may now vary from 1 (fixnum =
(signed-byte 63)) to 3 (fixnum = (signed-byte 61)) at build-time.
+ * enhancement: SB-EXT:WAIT-FOR allows waiting for arbitrary events.
* minor(?) incompatible(?) change: The default fixnum width on 64-bit
targets is now 63 bits (up from 61).
* enhancement: DESCRIBE now reports a lambda-list and source location
GETF, LOGBITP, LDB, and MASK-FIELD now arrange for non-primary values
of multiple-valued places to be set to NIL, instead of signalling an
error (per a careful reading of CLHS 5.1.2.3).
+ * bug fix: floating-point traps now work on darwin/x86 and /x86-64.
+ * bug fix: repair crash in x86oid darwin signal handling emulation
+ when built with certain compilers.
+ * bug fix: SB-ROTATE-BYTE misrotated to the right when using constant
+ rotation arguments on x86-64. (lp#882151)
changes in sbcl-1.0.52 relative to sbcl-1.0.51:
* enhancement: ASDF has been updated to version 2.017.
