* Two new convenience functions $_cimag and $_creal that extract the
imaginary and real parts respectively from complex numbers.
+* New built-in convenience variables $_shell_exitcode and $_shell_exitsignal

* Python API
** The gdb.Value type has a new method 'format_string' which returns a
** gdb.Type has a new property 'objfile' which returns the objfile the
type was defined in.

a style name in their output using its own style, to help
the user visualize the different styles.
+set print raw-frame-arguments
+show print raw-frame-arguments
+
+ These commands replace the similarly-named "set/show print raw
+ frame-arguments" commands (now with a dash instead of a space). The
+ old commands are now deprecated and may be removed in a future
+ release.
+
+maint test-options require-delimiter

+ Commands used by the testsuite to validate the command options
+ framework.
+
+* New command options, command completion
+
+ GDB now has a standard infrastructure to support dash-style command
+ options ('-OPT'). One benefit is that commands that use it can
+ easily support completion of command line arguments. Try "CMD
+ -[TAB]" or "help CMD" to find options supported by a command. Over
+ time, we intend to migrate most commands to this infrastructure. A
+ number of commands got support for new command options in this
+ release:
+
+ ** The "print" and "compile print" commands now support a number of
+ options that allow overriding relevant global print settings as
+ set by "set print" subcommands:
+
+ -address [on|off]
+ -array [on|off]
+ -array-indexes [on|off]
+ -elements NUMBER|unlimited
+ -null-stop [on|off]
+ -object [on|off]
+ -pretty [on|off]
+ -repeats NUMBER|unlimited
+ -static-members [on|off]
+ -symbol [on|off]
+ -union [on|off]
+ -vtbl [on|off]
+
+ Note that because the "print"/"compile print" commands accept
+ arbitrary expressions which may look like options (including
+ abbreviations), if you specify any command option, then you must
+ use a double dash ("--") to mark the end of argument processing.
+
+ ** The "backtrace" command now supports a number of options that
+ allow overriding relevant global print settings as set by "set
+ backtrace" and "set print" subcommands:
+
+ -entry-values no|only|preferred|if-needed|both|compact|default
+ -frame-arguments all|scalars|none
+ -raw-frame-arguments [on|off]
+ -past-main [on|off]
+ -past-entry [on|off]
+
+ In addition, the full/no-filters/hide qualifiers are now also
+ exposed as command options too:
+
+ -full
+ -no-filters
+ -hide
+
+ ** The "frame apply", "tfaas" and "faas" commands similarly now
+ support the following options:
+
+ -past-main [on|off]
+ -past-entry [on|off]
+
+ All options above can also be abbreviated. The argument of boolean
+ (on/off) options can be 0/1 too, and also the argument is assumed
+ "on" if omitted. This allows writing compact command invocations,
+ like for example:
+
+ (gdb) p -r -p -o 0 -- *myptr
+
+ The above is equivalent to:
+
+ (gdb) print -raw -pretty -object off -- *myptr
+
+* Completion improvements
+
+ ** GDB can now complete the options of the "thread apply all" and
+ "taas" commands, and their "-ascending" option can now be
+ abbreviated.
+
+ ** GDB can now complete the options of the "info threads" command.
+
+ ** GDB can now complete the options of the "compile file" and
+ "compile code" commands. The "compile file" command now
+ completes on filenames.
+
+ ** GDB can now complete the backtrace command's
+ "full/no-filters/hide" qualifiers.
+
+* In settings, you can now abbreviate "unlimited".
+
+ E.g., "set print elements u" is now equivalent to "set print
+ elements unlimited".
* New MI commands
were to be given as a command itself. This is intended for use by MI
frontends in cases when separate CLI and MI channels cannot be used.
+-catch-throw, -catch-rethrow, and -catch-catch
+ These can be used to catch C++ exceptions in a similar fashion to
+ the CLI commands 'catch throw', 'catch rethrow', and 'catch catch'.

* Testsuite
The testsuite now creates the files gdb.cmd (containing the arguments
