~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This release supports X86/Linux, AMD64/Linux, ARM32/Linux, ARM64/Linux,
PPC32/Linux, PPC64BE/Linux, PPC64LE/Linux, S390X/Linux, MIPS32/Linux,

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

* ==================== CORE CHANGES ===================
* When GDB is used to debug a program running under valgrind using
the valgrind gdbserver, GDB will automatically load some
python code provided in valgrind defining GDB front end commands
corresponding to the valgrind monitor commands.
These GDB front end commands accept the same format as
the monitor commands directly sent to the Valgrind gdbserver.
These GDB front end commands provide a better integration
in the GDB command line interface, so as to use for example
GDB auto-completion, command specific help, searching for
a command or command help matching a regexp, ...
For relevant monitor commands, GDB will evaluate arguments
to make the use of monitor commands easier.
For example, instead of having to print the address of a variable
to pass it to a subsequent monitor command, the GDB front end
command will evaluate the address argument. It is for example
possible to do:
(gdb) memcheck who_points_at &some_struct sizeof(some_struct)
instead of:
(gdb) p &some_struct
$2 = (some_struct_type *) 0x1130a0 <some_struct>
(gdb) p sizeof(some_struct)
$3 = 40
(gdb) monitor who_point_at 0x1130a0 40
* The vgdb utility now supports extended-remote protocol when
invoked with --multi. In this mode the GDB run command is
supported. Which means you don't need to run gdb and valgrind
from different terminals. So for example to start your program
in gdb and run it under valgrind you can do:
$ gdb prog
(gdb) set remote exec-file prog
(gdb) set sysroot /
(gdb) target extended-remote | vgdb --multi
(gdb) start
* The behaviour of realloc with a size of zero can now
be changed for tools that intercept malloc. Those
tools are memcheck, helgrind, drd, massif and dhat.
Realloc implementations generally do one of two things
- free the memory like free() and return NULL
(GNU libc and ptmalloc).
- either free the memory and then allocate a
minimum sized block or just return the
original pointer. Return NULL if the
allocation of the minimum sized block fails
(jemalloc, musl, snmalloc, Solaris, macOS).
When Valgrind is configured and built it will
try to match the OS and libc behaviour. However
if you are using a non-default library to replace
malloc and family (e.g., musl on a glibc Linux or
tcmalloc on FreeBSD) then you can use a command line
option to change the behaviour of Valgrind:
--realloc-zero-bytes-frees=yes|no [yes on Linux glibc, no otherwise]
* ================== PLATFORM CHANGES =================
* Make the address space limit on FreeBSD amd64 128Gbytes
(the same as Linux and Solaris, it was 32Gbytes)
* ==================== TOOL CHANGES ===================
* Memcheck:
- When doing a delta leak_search, it is now possible to only
output the new loss records compared to the previous leak search.
This is available in the memcheck monitor command 'leak_search'
by specifying the "new" keyword or in your program by using
the client request VALGRIND_DO_NEW_LEAK_CHECK.
Whenever a "delta" leak search is done (i.e. when specifying
"new" or "increased" or "changed" in the monitor command),
the new loss records have a "new" marker.
- Valgrind now contains python code that defines GDB memcheck
front end monitor commands. See CORE CHANGES.
- Performs checks for the use of realloc with a size of zero.
This is non-portable and a source of errors. If memcheck
detects such a usage it will generate an error
realloc() with size 0
followed by the usual callstacks.
A switch has been added to allow this to be turned off:
--show-realloc-size-zero=yes|no [yes]
* Helgrind:
- The option ---history-backtrace-size=<number> allows to configure
the number of entries to record in the stack traces of "old"
accesses. Previously, this number was hardcoded to 8.
- Valgrind now contains python code that defines GDB helgrind
front end monitor commands. See CORE CHANGES.
* Cachegrind:
- `--cache-sim=no` is now the default. The cache simulation is old and
unlikely to match any real modern machine. This means only the `Ir`
event are gathered by default, but that is by far the most useful
event.
- `cg_annotate`, `cg_diff`, and `cg_merge` have been rewritten in
Python. As a result, they all have more flexible command line
argument handling, e.g. supporting `--show-percs` and
`--no-show-percs` forms as well as the existing `--show-percs=yes`
and `--show-percs=no`.
- `cg_annotate` has some functional changes.
- It's much faster, e.g. 3-4x on common cases.
- It now supports diffing (with `--diff`, `--mod-filename`, and
`--mod-funcname`) and merging (by passing multiple data files).
- It now provides more information at the file and function level.
There are now "File:function" and "Function:file" sections. These
are very useful for programs that use inlining a lot.
- Support for user-annotated files and the `-I`/`--include` option
has been removed, because it was of little use and blocked other
improvements.
- The `--auto` option is renamed `--annotate`, though the old
`--auto=yes`/`--auto=no` forms are still supported.
- `cg_diff` and `cg_merge` are now deprecated, because `cg_annotate`
now does a better job of diffing and merging.
- The Cachegrind output file format has changed very slightly, but in
ways nobody is likely to notice.
* Callgrind:
- Valgrind now contains python code that defines GDB callgrind
front end monitor commands. See CORE CHANGES.
* Massif:
- Valgrind now contains python code that defines GDB massif
front end monitor commands. See CORE CHANGES.
* DHAT:
- A new kind of user request has been added which allows you to
override the 1024 byte limit on access count histograms for blocks
of memory. The client request is DHAT_HISTOGRAM_MEMORY.
* ==================== 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
