Release 3.24.0 (31 Oct 2024)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This release supports X86/Linux, AMD64/Linux, ARM32/Linux, ARM64/Linux,
PPC32/Linux, PPC64BE/Linux, PPC64LE/Linux, S390X/Linux, MIPS32/Linux,
MIPS64/Linux, ARM/Android, ARM64/Android, MIPS32/Android, X86/Android,
X86/Solaris, AMD64/Solaris, AMD64/MacOSX 10.12, X86/FreeBSD, AMD64/FreeBSD
and ARM64/FreeBSD  There is also preliminary support for X86/macOS 10.13,
AMD64/macOS 10.13 and nanoMIPS/Linux.

* ==================== CORE CHANGES ===================

* Bad file descriptor usage now generates a real error with
  --track-fds=yes that is suppressible and shows up in the xml output
  with full execution backtrace. The warnings shown without using the
  option are deprecated and will be removed in a future valgrind
  version.

* Ada name demangling is now supported in error messages.

* ================== PLATFORM CHANGES =================

* S390X added support for the DFLTCC instruction provided by the
  deflate-conversion facility (z15/arch13).

* S390X added support for the instructions provided by the MSA facility
  and MSA extensions 1-9.

* ==================== TOOL CHANGES ===================

* ==================== FIXED BUGS ====================

The following bugs have been fixed or resolved.  Note that "n-i-bz"
stands for "not in bugzilla" -- that is, a bug that was reported to us
but never got a bugzilla entry.  We encourage you to file bugs in
bugzilla (https://bugs.kde.org/enter_bug.cgi?product=valgrind) rather
than mailing the developers (or mailing lists) directly -- bugs that
are not entered into bugzilla tend to get forgotten about or ignored.
