We are pleased to announce a new release of Valgrind, version 3.22.0,
available from https://valgrind.org/downloads/current.html.
See the release notes below for details of changes.
Our thanks to all those who contribute to Valgrind's development. This
release represents a great deal of time, energy and effort on the part
of many people.
Happy and productive debugging and profiling,
-- The Valgrind Developers

AMD64/macOS 10.13 and nanoMIPS/Linux.
* ==================== CORE CHANGES ===================
* A new configure option --with-gdbscripts-dir lets you install
the gdb valgrind python monitor scripts in a specific location.
For example a distro could use it to install the scripts in a
safe load location --with-gdbscripts-dir=%{_datadir}/gdb/auto-load
It is also possible to configure --without-gdb-scripts-dir so no
.debug_gdb_scripts section is added to the vgpreload library and
no valgrind-monitor python scripts are installed at all.
* ================== PLATFORM CHANGES =================
* Support has been added for FreeBSD 14 and FreeBSD 15.
* Add support for the folllowing FreeBSD system calls:
close_range, kqueuex, membarrier, timerfd_create,
timerfd_settime and timerfd_gettime (all added in FreeBSD 15).
* ==================== TOOL CHANGES ===================
* Memcheck now tests and warns about the values used for
alignment and size. These apply to various functions: memalign,
posix_memalign and aligned_alloc in C and various overloads
of operators new and delete in C++. The kinds of error that can
be detected are
- invalid alignment, for instance the alignment is usually required
to be a power of 2
- mismatched alignment between aligned allocation and aligned
deallocation
- mismatched size when sized delete is used
- bad size for functions that have implementation defined behaviour
when the requested size is zero
* Cachegrind:
- You can now profile part of a program's execution using the new
`CACHEGRIND_START_INSTRUMENTATION` and `CACHEGRIND_STOP_INSTRUMENTATION`
client requests, along with the new `--instr-at-start` option. The
behaviour is the same as Callgrind's equivalent functionality.
* ==================== 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.
