            GDB 11.1 released!

Release 11.1 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 FTP server in the directory:

The vital stats:

  Size   md5sum                            Name
  22MiB  257cb0f67927f79acf636d8c01e19990  gdb-11.1.tar.xz
  37MiB  eb6596d83bdccea06caa6d49d923e119  gdb-11.1.tar.gz

There is a web page for GDB at:

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 11.1 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

* 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'

  ** 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

* 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)
