+set print frame-arguments
+ The new value 'presence' indicates to only indicate the presence of
+ arguments using ..., instead of printing argument names and values.
+
+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.

+
+* 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]
+ -frame-info auto|source-line|location|source-and-location
+ |location-and-address|short-location
+ -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]
+
+ ** The new "info sources" options -dirname and -basename options
+ are using the standard '-OPT' infrastructure.
+
+ 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
+
+ ** The "info types" command now supports the '-q' flag to disable
+ printing of some header information in a similar fashion to "info
+ variables" and "info functions".
+
+ ** The "info variables", "info functions", and "whereis" commands
+ now take a '-n' flag that excludes non-debug symbols (symbols
+ from the symbol table, not from the debug info such as DWARF)
+ from the results.
+
+* 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", "info
+ functions", "info variables", "info locals", and "info args"
+ commands.
+
+ ** 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".
