Release 3.18.0 (15 Oct 2021)

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 and
AMD64/FreeBSD.  There is also preliminary support for X86/macOS 10.13,
AMD64/macOS 10.13 and nanoMIPS/Linux.

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

* The libiberty demangler has been updated, which brings support for
  Rust v0 name demangling

* __libc_freeres isn't called anymore after the program recieves a
  fatal signal. Causing some internal glibc resources to hang around,
  but preventing any crashes after the program has ended.

* The DWARF reader is now very much faster at startup when just
  --read-inline-info=yes (the default in most cases) is given.

* glibc 2.34, which moved various functions from libpthread.so into
  libc.so, is now supported.

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

* arm64:

  - v8.2 scalar and vector FABD, FACGE, FACGT and FADD.
  - v8.2 FP compare & conditional compare instructions.
  - Zero variants of v8.2 FP compare instructions.

* s390:

  - Support the miscellaneous-instruction-extensions facility 3 and
    the vector-enhancements facility 2.  This enables programs
    compiled with "-march=arch13" or "-march=z15" to be executed
    under Valgrind.

* ppc64:

  - ISA 3.1 support is now complete
  - ISA 3.0 support for the darn instruction added.
  - ISA 3.0 support for the vector system call instruction scv added.
  - ISA 3.0 support for the copy, paste and cpabort instructions added.
* Support for X86/FreeBSD and AMD64/FreeBSD has been added.

* ==================== OTHER CHANGES ====================

* Memcheck on amd64: minor fixes to remove some false positive
  undef-value errors

* ==================== 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.
