[Sbcl-announce] sbcl-2.4.9 released

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

Dear all,

Following a relatively quite development month, with many changes to
internals but relatively few directly user-visible changes (which are
nevertheless summarized below), I have tagged SBCL 2.4.9 and uploaded
artifacts to SourceForge.  There has been additional progress on merging
the adaptive hash-table work presented by Gábor Melis at ELS24 -- which
is good, because ELS25 has just been announced; maybe see some of you in
Zürich in May 2025?

Best wishes,

Christophe

changes in sbcl-2.4.9 relative to sbcl-2.4.8:
  * minor incompatible change: FIND, POSITION (and variants) now check :START
    and :END arguments for validity as bounding index designators for list
    sequences.
  * platform support:
    ** improve support for Solaris and variants on x86 and x86-64.  (thanks to
       Masatoshi SANO)
    ** fix a bug in handling timeouts and interrupted system calls in
       SB-UNIX:UNIX-SIMPLE-POLL.  (lp#2078824, thanks to Michał phoe Herda)
    ** fix a bug in the lisp understanding of ssize_t under Windows.
    ** fix large constant encoding in RISC-V.  (lp#2077307, reported by
       Guillaume LE VAILLANT)
    ** more parsimonious low-level type tests on arm64.
    ** building from the result of git-archive should complete without error.
  * bug fix: exporting a symbol during package iteration no longer skips other
    symbols.  (lp#2080387, reported by kbhit)
  * optimization: improvements to EQ hash tables and associated hash functions.
  * optimization: type checking of string and string-designator is more efficient.
  * optimization: the compiler better understands the nature of the results of
    CONCATENATE.
