[Christophe R. <cs...@ca...>]

Dear all,

It's the loveliest time of the year to get a shiny new SBCL release.
Find the SBCL 2.5.11 sources and some binary artifacts available for
download at SourceForge, tagged in version control, or with your
friendliest purveyor of seasonal gifts; while you wait for your
delivery, peruse the list of changes in this released appended below.
As ever, please report any problems you may have to the bug tracker on
launchpad or to the mailing lists.

changes in sbcl-2.5.11 relative to sbcl-2.5.10:
  * incompatible change: the compiler's internal representation of "source
    paths" for unquoted forms within backquotes has changed.  Other developer
    tools using this representation, including callers of some exported
    SB-INTROSPECT functions, will misreport the location of signalled
    conditions and/or definitions in top-level forms including backquotes and
    commas.
  * minor incompatible change: undefined syntaxes following
    *READ-BASE*-related reader macros (such as #B, #O, #X, #R) now signal
    reader errors.
  * minor incompatible change: the convenience reader syntax pkg::(...) no
    longer triggers package locks for the PKG package.
  * minor incompatible change: building with the SB-DEVEL feature inhibits
    identical code folding at the end of the build of the SBCL system itself.
  * enhancement: improve the compiler's knowledge of the dimensions of the
    result of MAKE-ARRAY.  (lp#2130477, thanks to Vasily Postnicov)
  * enhancement: the SB-COVER contributed module has been made substantially
    more robust; collecting coverage no longer inhibits various CLOS
    optimizations.  (For SBCL developers, it is now capable of reporting on
    the coverage of the SBCL system itself, provided it is built with the new
    :SB-COVER-FOR-INTERNALS build-time feature.)
  * bug fix: REQUIREing the SB-MD5 contributed module no longer installs a
    compiler optimization policy restriction of SPACE being at least 1.
  * bug fix: don't miscompute the sizes of garbage collector data structures
    for running with dynamic space heap sizes above 128GiB.
  * bug fix: ENOUGH-NAMESTRING when the pathname and defaults arguments are
    both logical pathnames with the same host returns a shorter string than
    previously.
  * bug fix: the compiler retains fewer temporary data structures when
    compiling code with coverage data.
  * bug fix: requiring the SB-MD5 contrib module no longer installs a
    restriction on the SPACE optimization quality.
  * bug fix: internal compiler floating point error while compiling certain calls
    to CEILING.  (lp#2132231)
  * bug fix: miscompilation of TYPEP on intersections of types including
    rational ranges.  (lp#2132207)
  * bug fix: miscompilation of MISMATCH from insufficiently cautious type
    derivation.  (lp#2132187)
  * bug fix: internal compiler error while compiling ASH from an incorrect
    consistency check.  (lp#2132156)
  * bug fix: internal compiler error from missing constant-folding stub for
    internal function.  (lp#2132126)
  * bug fix: miscompilation of GET-PROPERTIES at low SAFETY optimization
    qualities.  (lp#2131985)
  * bug fix: internal compiler error while generating code for multiplications
    of fixnums where the result is also asserted to be a fixnum. (lp#2131894)
  * bug fix: the asserted real range of ATANH was incorrectly stated as
    [-1,1].  (lp#2131711)
  * bug fix: incorrect type error resulting from wrong type derivation of
    REDUCE #'LOGIOR.  (lp#2131699)
  * bug fix: specialized XEPs should not be generated during
    block-compilation or interpretation.  (lp#2131118)
  * bug fix: fix a wrong compiler transform for MAKE-ARRAY leading to
    miscompilation.  (lp#2131048)
  * bug fix: miscompilation of type checks of (UNSIGNED-BYTE <X>) for large
    <X>.  (lp#2130028)
  * bug fix: it is now possible to inline functions containing SPECIAL
    declarations on symbols in locked packages.  (lp#2129827, reported by
    Scott L. Burson)
  * bug fix: various internal compiler errors.  (lp#2132022, lp#2129649)
  * bug fix: various wrong results and inconsistencies from SUBTYPEP on ARRAY
    types.  (lp#2130374, lp#2130424, lp#2130441, lp#2130457, lp#2130508,
    lp#2130518, lp#2130526, lp#2130542, lp#2130588, lp#2130950, lp#2131079,
    lp#2131149, lp#2131179, lp#2131186, lp#2131271, lp#2131618, lp#2130262)
  * optimization: LOGTEST participates in compiler transforms related to
    modular (machine-sized) arithmetic.
  * optimization: more arithmetic combinations simplifications.
  * optimization: (car (list a)) doesn't allocate a list.
