sbcl-0.8.13 released

sbcl-0.8.13 has been released. Sources are available already; Brian
Mastenbrook has volunteered to make some binaries available presently
as well.

from the NEWS file in the distribution:
changes in sbcl-0.8.13 relative to sbcl-0.8.12:
  * new feature: SB-PACKAGE-LOCKS. See the "Package Locks" section of
    the manual for details; for now, package locks can be disabled by
    removing :SB-PACKAGE-LOCKS in customize-target-features.lisp, but
    if no major problems are found then it is likely that they will be
    compiled in unconditionally.
  * major incompatible change: LOAD-FOREIGN and LOAD-1-FOREIGN are now
    unsupported operators on all platforms.  To load a shared library
    into SBCL, use SB-ALIEN:LOAD-SHARED-OBJECT.  To load a non-shared
    object file, link it into a shared library outside of SBCL and
    load it using SB-ALIEN:LOAD-SHARED-OBJECT.  (incidentally fixes
    bug #79)
  * bug workaround: ROOM T and the GC were not working together
    reliably, because invariants expected by the SB!VM:INSTANCE-USAGE
    reporting facility aren't preserved. That reporting has been
    disabled, so now until and unless someone figures out how to make it
    work reliably with the current GC, (ROOM T) is equivalent to (ROOM).
  * minor incompatible change: as threatened around sbcl-0.8.0, the
    home package of MOP-related symbols is now SB-MOP, not SB-PCL.
    The symbols are also exported from SB-PCL for backwards
    compatibility, but more so than before SB-PCL should be treated as
    an implementation-internal package.
  * fasl format changed: SBCL 0.8.13 fasls are incompatible with those
    of earlier versions
  * the SB-SPROF contrib now works on (most) non-x86 architectures.
    It is known as of this release not to work on the Alpha, however.
  * fixed bug #167: errors signalled due to illegal syntax in method 
    bodies are now more legible.
  * fixed bug #338: instances of EQL-SPECIFIER are now valid type
    designators and can hence be used with TYPEP.
  * fixed bug #333: CHECK-TYPE now ensures that the type error
    signalled, if any, has the right object to be accessed by
    TYPE-ERROR-DATUM.  (reported by Tony Martinez)
  * fixed bug #340: SETF of VALUES obeys the specification in ANSI
    5.1.2.3 for multiple-value place subforms.  (reported by Kalle
    Olavi Niemetalo)
  * fixed bug #334: programmatic addition of slots using specialized
    methods on SB-MOP:COMPUTE-SLOTS works for :ALLOCATION :INSTANCE
    and :ALLOCATION :CLASS slots.
  * fixed bug #269: SCALE-FLOAT scales floats by any integer, not just
    float exponents.  (rereported by Peter Seibel)
  * fixed a bug: #\Space (and other whitespace characters) are no
    longer considered to be macro characters in standard syntax by
    GET-MACRO-CHARACTER.
  * fixed bug: initialization of condition class metaobjects no longer
    causes an instance of the condition to be created.  (reported by
    Marco Baringer)
  * fixed bug: it is now possible to have slots such that
    SB-MOP:SLOT-DEFINITION-ALLOCATION of the effective slot
    description is neither :INSTANCE nor :CLASS.
  * fixed bug: the ctor optimization of MAKE-INSTANCE now respects
    user-defined methods on SLOT-BOUNDP-USING-CLASS and (SETF
    SLOT-VALUE-USING-CLASS), and no longer causes errors with
    non-standard SLOT-DEFINITION-ALLOCATION values.
  * fixed bugs: various race conditions handling exiting threads.  
    CL-PPCRE's thread torture test now passes.
  * fixed arguably-a-bug: GC time proportional to number of threads in 
    system even when most of them are idle
  * optimization: improved performance of BIT and SBIT on bit-vectors.
  * .fasl file incompatibility: The fasl file version number has
    been incremented because of changes associated with package locks.
