sbcl-1.4.13 released

Dear all,

I have released sbcl-1.4.13 and uploaded a source tarball and an x86-64
binary to SourceForge.  The somewhat laconic list of major changes is
appended to this message; there are some other changes, ideally not
user-visible, such as: folding identical code in building the system
itself, ideally resulting in a more compact core; and fixing a few
errors in the garbage collector, which might cause memory corruption in
rare circumstances.  As ever, download responsibly, and please report
any problems.

Best wishes,

Christophe

changes in sbcl-1.4.13 relative to sbcl-1.4.12:
  * minor incompatible change: PRINT-TYPE and PRINT-TYPE-SPECIFIER are not
    exported from SB-EXT. These were never announced, so this change would
    only affects users who discovered these undocumented functions.
  * enhancement: SB-EXT:SEARCH-ROOTS and SB-EXT:GC-AND-SEARCH-ROOTS
    are supported on all backends that use gencgc.
