sbcl-0.9.6 has been released

SBCL 0.9.6 is now in the usual places on SourceForge. Use it wisely.

from the NEWS file in the distribution:
changes in sbcl-0.9.6 relative to sbcl-0.9.5:
  * bug fix: add a workaround to SBCL looping infinitely at startup on
    Linux kernels with apparently buggy implementations of personality().
    (thanks to Svein Ove Aas)
  * bug fix: Unicode symbols are correctly printed in LDB backtraces
    (thanks to David Lichteblau)
  * bug fix: local bindings shadow global symbol macros for
    macroexpansion.  (reported by Matthew D Swank on comp.lang.lisp)
  * optimization: non-open coded uses of numeric comparison operators
    (e.g. >) no longer cons when called with more than one parameter
    on platforms supporting dynamic-extent allocation.
  * enhancement: saving cores with foreign code loaded is now supported
    on MIPS/Linux in addition to the previously supported platforms.
  * bug fix: FIND-RESTART now tests for activity, not applicability when given
    a restart object as identifier. (reported by Helmut Eller for CMUCL)
  * bug fix: division by zero in sb-sprof when no samples were collected
  * bug fix: a race when a slow to arrive sigprof signal killed sbcl
  * bug fix: asdf-install uses CRLF as required by the HTTP spec.
    (thanks to Alexander Kjeldaas)
  * new feature: ignoring the return values of destructive functions
    like NREVERSE signals a compile-time style-warning.
    (thanks to Kevin Reid)
  * new feature: the alignment of alien structure fields can be
    explicitly specified. (thanks to Cyrus Harmon)
  * bug fix: run cleanup forms (in all threads) when receiving a SIGTERM
    and dump core on SIGQUIT
  * threads
    ** incompatible change: threads do not inherit values of specials
       from their parents (see manual)
    ** bug fix: threads stacks belonging to dead threads are freed by the
       next exiting thread, no need to gc to collect thread stacks anymore
    ** minor incompatible change: INTERRUPT-THREAD-ERROR-ERRNO removed
    ** WITH-RECURSIVE-LOCK can be nested in a WITH-MUTEX for the same lock
    ** bug fix: dynamic variable and thread start related gc lossage
    ** bug fix: job control (SIGSTOP/SIGCONT) no longer confuses threads
       suspended for gc
  * fixed some bugs revealed by Paul Dietz' test suite:
    ** SUBTYPEP is slightly more accurate on heinously complicated
       CONS types where some of the members have uncertain (in the
       NIL, NIL sense) type relationships to each other.
  * GENCGC
    ** Cores produced by SAVE-LISP-AND-DIE on GENCGC platforms are
       no longer purified unless :PURIFY T is explicitly specified.
    ** Non-purified cores are significantly smaller than before
