Feb 19th, 2023: GDB 13.1 Released!

The latest version of GDB, version 13.1, is available for download.
This version of GDB includes the following changes and enhancements:
Support for the following new targets has been added in both GDB and GDBserver:
GNU/Linux/LoongArch (gdbserver) loongarch*-*-linux*
GNU/Linux/CSKY (gdbserver) csky*-*linux*
The Windows native target now supports target async.
FreeBSD:
Arm and AArch64: Support for Thread Local Storage (TLS) variables
Hardware watchpoint support on AArch64 FreeBSD
Floating-point support has now been added on LoongArch GNU/Linux.
New commands:
set print nibbles [on|off]
show print nibbles

This controls whether the 'print/t' command will display binary
values in groups of four bits, known as "nibbles". The default is
'off'.

Various styling-related commands. See the gdb/NEWS file for more details.
Various maintenance commands. These are normally aimed at GDB
experts or developers. See the gdb/NEWS file for more details.

Python API improvements:
New Python API for instruction disassembly.

The new attribute 'locations' of gdb.Breakpoint returns a list of
gdb.BreakpointLocation objects specifying the locations where the
breakpoint is inserted into the debuggee.
New Python type gdb.BreakpointLocation.
New function gdb.format_address(ADDRESS, PROGSPACE, ARCHITECTURE)
that formats ADDRESS as 'address '
New function gdb.current_language that returns the name of the
current language. Unlike gdb.parameter('language'), this will never
return 'auto'.
New function gdb.print_options that returns a dictionary of the
prevailing print options, in the form accepted by gdb.Value.format_string.
New method gdb.Frame.language that returns the name of the frame's language.
gdb.Value.format_string now uses the format provided by 'print',
if it is called during a 'print' or other similar operation.
gdb.Value.format_string now accepts the 'summary' keyword. This
can be used to request a shorter representation of a value, the
way that 'set print frame-arguments scalars' does.
The gdb.register_window_type method now restricts the set of
acceptable window names. The first character of a window's name
must start with a character in the set [a-zA-Z], every subsequent
character of a window's name must be in the set [-_.a-zA-Z0-9].
` GDB/MI changes:  MI version 1 is deprecated, and will be removed
in GDB 14.  The async record stating the stopped reason 'breakpoint-hit'
now contains an optional field locno.

Miscellaneous improvements:
gdb now supports zstd compressed debug sections (ELFCOMPRESS_ZSTD) for ELF.
New convenience variable $_inferior_thread_count contains the number
of live threads in the current inferior.
New convenience variables $_hit_bpnum and $_hit_locno, set to the
breakpoint number and the breakpoint location number of the breakpoint
last hit.
The "info breakpoints" now displays enabled breakpoint locations
of disabled breakpoints as in the "y-" state.
The format of 'disassemble /r' and 'record instruction-history /r'
has changed to match the layout of GNU objdump when disassembling.

A new format "/b" has been introduce to provide the old behavior of "/r".
The TUI no longer styles the source and assembly code highlighted
by the current position indicator by default. You can however
re-enable styling using the new "set style tui-current-position"
command.
It is now possible to use the "document" command to document
user-defined commands.
Support for memory tag data for AArch64 MTE.
Support Removal notices:
DBX mode has been removed.
Support for building against Python version 2 has been removed. It
is now only possible to build GDB against Python 3.
Support for the following commands has been removed:

set debug aix-solib on|off
show debug aix-solib
set debug solib-frv on|off
show debug solib-frv

Use the "set/show debug solib" commands instead.
See the NEWS file for a more complete and detailed list of what
this release includes.

Multithreaded symbol loading is now enabled by default

Deprecation Notices:
GDB 12 is the last release of GDB that will support building against Python 2
DBX mode is deprecated, and will be removed in GDB 13
GDB/MI changes:
The '-add-inferior' with no option flags now inherits the connection
of the current inferior, this restores the behaviour of GDB as it
was prior to GDB 10.
The '-add-inferior' command now accepts a '--no-connection' option,
which causes the new inferior to start without a connection.

Python API enhancements:
It is now possible to add GDB/MI commands implemented in Python
New function gdb.Architecture.integer_type()
New gdb.events.gdb_exiting event
New 'gdb.events.connection_removed' event registry
New gdb.TargetConnection object
New gdb.Inferior.connection property
New read-only attribute gdb.InferiorThread.details
New gdb.RemoteTargetConnection.send_packet method
New read-only attributes gdb.Type.is_scalar and gdb.Type.is_signed
The gdb.Value.format_string method now takes a 'styling' argument
Various new function in the "gdb" module
Miscellaneous:
The FreeBSD native target now supports async mode

Improved C++ template support
Support for disabling source highlighting through GNU of the Pygments
library instead.
The "print" command has been changed so as to print floating-point
values with a base-modifying formats such as "/x" to display the
underlying bytes of the value in the desired base.
The "clone-inferior" command now ensures that the TTY, CMD and ARGS
settings are copied from the original inferior to the new one. All
modifications to the environment variables done using the 'set
environment' or 'unset environment' commands are also copied to
the new inferior.
Various new commands have been introduced

See the NEWS file for a more complete and detailed list of what
this release includes.

September 13th, 2021: GDB 11.1 Released!
The latest version of GDB, version 11.1, is available for download.

This version of GDB includes the following changes and enhancements:

Support for ARM Symbian (arm*-*-symbianelf*) has been removed.
Building GDB now requires GMP (The GNU Multiple Precision Arithmetic Library).
New command-line options "--early-init-command" (or "-eix") and
"--early-init-eval-command" (or "-eiex")

GDB/MI Changes:
New --qualified option for the '-break-insert' and '-dprintf-insert' commands.
New --force-condition option for the '-break-insert' and
'-dprintf-insert' commands.
New --force option for the '-break-condition' command.
The '-file-list-exec-source-files' now accepts an optional regular
expression to filter the source files included in the result.
The results from '-file-list-exec-source-files' now include a
'debug-fully-read' field to indicate if the corresponding source's
debugging information has been partially read (false) or has been
fully read (true).

TUI Improvements:
Mouse actions are now supported. The mouse wheel scrolls the
appropriate window.  Key combinations that do not have a specific
action on the focused window are now passed to GDB.

Python enhancements:
Inferior objects now contain a read-only 'connection_num' attribute
that gives the connection number as seen in 'info connections' and
'info inferiors'.
New method gdb.Frame.level() which returns the stack level of the frame object.
New method gdb.PendingFrame.level() which returns the stack level
of the frame object.
When hitting a catchpoint, the Python API will now emit a
gdb.BreakpointEvent rather than a gdb.StopEvent. The gdb.Breakpoint
attached to the event will have type BP_CATCHPOINT.
Python TUI windows can now receive mouse click events. If the Window
object implements the click method, it is called for each mouse
click event in this window.  New setting "python ignore-environment
on|off"; if "on", causes GDB's builtin Python to ignore any
environment variable that would otherwise affect how Python behaves
(needs to be set during "early initialization" (see above).  New
setting "python dont-write-bytecode auto|on|off".

Guile API enhancements:
Improved support for rvalue reference values.
New procedures for obtaining value variants: value-reference-value,
value-rvalue-reference-value and value-const-value.
New "qMemTags" and "QMemTags" remote protocol packets (associated
with Memory Tagging).
GDB will now look for the .gdbinit file in a config directory before
looking for ~/.gdbinit. The file is searched for in the following
locations: $XDG_CONFIG_HOME/gdb/gdbinit, $HOME/.config/gdb/gdbinit,
$HOME/.gdbinit. On Apple hosts the search order is instead:
$HOME/Library/Preferences/gdb/gdbinit, $HOME/.gdbinit.  The "break
[...] if CONDITION" command no longer returns an error when the
condition is invalid at one or more locations. Instead, if the
condition is valid at one or more locations, the locations where
the condition is not valid are disabled.
The behavior of the "condition" command is changed to match the
new behavior of the "break" command.

Support for general memory tagging functionality (currently limited
to AArch64 MTE)

Core file debugging now supported for x86_64 Cygwin programs.
New "org.gnu.gdb.riscv.vector" feature for RISC-V targets.
GDB now supports fixed point types which are described in DWARF as
base types with a fixed-point encoding. Additionally, support for
the DW_AT_GNU_numerator and DW_AT_GNU_denominator has also been
added.

Miscellaneous:
New "startup-quietly on|off" setting; when "on", behaves the same
as passing the "-silent" option on the command line.
New "print type hex on|off" setting; when 'on', the 'ptype' command
uses hexadecimal notation to print sizes and offsets of struct
members. When 'off', decimal notation is used.
The "inferior" command, when run without argument, prints information
about the current inferior.
The "ptype" command now supports "/x" and "/d", affecting the base
used to print sizes and offsets.
The output of the "info source" has been restructured.
New "style version foreground | background | intensity" commands
to control the styling of the GDB version number.
Various debug and maintenance commands (mostly useful for the GDB
developers) See the NEWS file for a more complete and detailed list
of what this release includes.

January 18th, 2025: GDB 16.1 Released!

    The latest version of GDB, version 16.1, is available for download.
    This version of GDB 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

    See the NEWS file for a more complete and detailed list of what this
    release includes.
