Nikodemus Siivola just announced that SBCL 1.0.19 has been released. From the announcement:
Source is available in SourceForge CVS and on the SourceForge File
changes in sbcl-1.0.19 relative to 1.0.18:
* new feature: user-customizable variable SB-EXT:*MUFFLED-WARNINGS*;
warnings that go otherwise unhandled will be muffled if they are
of the type that's the value of this variable.
* optimization: stack allocation is slightly more efficient on x86
* bug fix: DEFSTRUCT forms with user-specified :CONSTRUCTOR options,
where a raw slot always is initialized using the initform whose
type is not know sufficiently well a compile-time are now compiled
correctly. (reported by John Morrison)
* bug fix: compiler no longer makes erronous assumptions in the
presense of non-foldable SATISFIES types.
* bug fix: stack analysis missed cleanups of dynamic-extent
arguments in non-let-converted calls to local functions.
* improvements to the Windows port:
** adjusted address spaces for building on both Win32 and
Win64. (thanks for John Connors)
* fixed some bugs revealed by Paul Dietz' test suite:
** interval arithmetic during type derivation used inexact integer
to single-float coercions.
** arithmetic operations involving large integers and single
floats give the same results in compiled and interpreted code.
** deriving the result type of COERCE no longer signals an error
if the derived type of the second argument is a MEMBER type
containing invalid type specifiers.
** ADJOIN with constant NIL as second argument works correctly.
** FUNCTION-KEYWORDS was called SB-PCL::FUNCTION-KEYWORD-PARAMETERS.
