GDB 16.2 released!
Release 16.2 of GDB, the GNU Debugger, is now available. GDB is
a source-level debugger for Ada, C, C++, Fortran, Go, Rust, and many
other languages. GDB can target (i.e., debug programs running on)
more than a dozen different processor architectures, and GDB itself
can run on most popular GNU/Linux, Unix and Microsoft Windows variants.
GDB is free (libre) software.
You can download GDB from the GNU HTTPS server in the directory:
https://ftp.gnu.org/gnu/gdb/?C=M;O=D

There is a web page for GDB at:
https://www.gnu.org/software/gdb/
That page includes information about GDB mailing lists (an announcement
mailing list, developers discussion lists, etc.), details on how to
access GDB's source repository, locations for development snapshots,
preformatted documentation, and links to related information around
the net. We will put errata notes and host-specific tips for this release
on-line as any problems come up. All mailing lists archives are also
browsable via the web.
GDB 16.2 brings the following fixes and enhancements over GDB 16.1:
* PR build/32578 (cannot build GDB 16.1 out of tree when calling the configure
script with a relative path)
* PR tui/32592 ([gdb/tui] internal error in tui-winsource.c:340:refresh_window)
* PR remote/32593 (Incompatibilities between GDB's and LLDB's 'x' packet
implementation)
* PR build/32610 (Missing #include file in darwin_nat.c)
GDB 16.1 includes the following changes and enhancements:
* record/replay support now available on loongarch*-linux*
* GDB now supports watchpoints for tagged data pointers.
* MTE (Memory Tagging Extension) debugging is now supported on AArch64
baremetal.
* New bash script gstack uses GDB to print stack traces of running processes.
* Enhanced breakpoint support
** For breakpoints that are created in the 'pending' state, any
'thread' or 'task' keywords are parsed at the time the breakpoint is
created, rather than at the time the breakpoint becomes non-pending.
** Thread-specific breakpoints are only inserted into the program space
in which the thread of interest is running.
* Enhanced Intel Processor Trace support
** Support for printing of asynchronous events
** Support for printing of ptwrite payloads
* Changed commands
** The "remove-symbol-file -a ADDRESS" command now accepts a full expression
as the ADDRESS.
** The "show configuration" command now prints the version of GNU
readline that GDB is using.
** The "maintenance print remote-registers" now provides an "Expedited"
column indicating which registers were included in the last stop reply
packet received by GDB.
** Various command taking filenames as argument now require file names
to be quoted if the argument contains white spaces or quote characters.
* Python API changes
** New module gdb.missing_objfile that facilitates dealing with
missing objfiles when opening a core-file. GDB commands to query,
enable and disable handlers created using this API have also
been added.
** New event gdb.tui_enabled.
** Added the gdb.Symbol.is_artificial attribute.
** New gdb.record.clear function to clear the trace data of
the current recording.
** The 'signed' argument to gdb.Architecture.integer_type() will no
longer accept non-bool types.
** The gdb.MICommand.installed property can only be set to True or
False.
** The 'qualified' argument to gdb.Breakpoint constructor will no
longer accept non-bool types.
* Debugger Adapter Protocol changes
** The "scopes" request will now return a scope holding global
variables from the stack frame's compilation unit.
** The "scopes" request will return a "returnValue" scope holding
the return value from the latest "stepOut" command, when
appropriate.
** The "launch" and "attach" requests were rewritten in accordance
with some clarifications to the spec. Now they can be sent at
any time after the "initialized" event, but will not take effect
(or send a response) until after the "configurationDone" request
has been sent.
** The "variables" request will not return artificial symbols.
* Remote Protocol
** New remote packet: vFile:stat
** New remote packet: x addr,length
* Miscellaneous
** The Ada 'Object_Size attribute is now supported.
** Styling now available for line numbers, GDB commands and header lines
of lists.
** It is now possible to turn the warning emitted when specifying
a language that does not match the current frame off.
** For ARM targets, the offset of the pc in the jmp_buf has been fixed
to match glibc 2.20 and later. This should only matter when not
using libc probes. This may cause breakage when using an incompatible
libc, like uclibc or newlib, or an older glibc.
* Deprecated or removed
** Support for QNX Neutrino has been removed
** Support for Nios II targets has been removed
** Support for Intel MPX has been removed
