+  provide the exitcode or exit status of the shell commands launched by

+
+* New commands
+
+| [COMMAND] | SHELL_COMMAND
+| -d DELIM COMMAND DELIM SHELL_COMMAND
+pipe [COMMAND] | SHELL_COMMAND
+pipe -d DELIM COMMAND DELIM SHELL_COMMAND
+  Executes COMMAND and sends its output to SHELL_COMMAND.
+  With no COMMAND, repeat the last executed command
+  and send its output to SHELL_COMMAND.
+
+set may-call-functions [on|off]
+show may-call-functions
+  This controls whether GDB will attempt to call functions in
+  the program, such as with expressions in the print command.  It
+  defaults to on.  Calling functions in the program being debugged
+  can have undesired side effects.  It is now possible to forbid
+  such function calls.  If function calls are forbidden, GDB will throw
+  an error when a command (such as print expression) calls a function
+  in the program.
+
+set print finish [on|off]
+show print finish
+  This controls whether the `finish' command will display the value
+  that is returned by the current function.  When `off', the value is
+  still entered into the value history, but it is not printed.  The
+  default is `on'.
+
+set print max-depth
+show print max-depth
+  Allows deeply nested structures to be simplified when printing by
+  replacing deeply nested parts (beyond the max-depth) with ellipses.
+  The default max-depth is 20, but this can be set to unlimited to get
+  the old behavior back.
+
+set logging debugredirect [on|off]
+  By default, GDB debug output will go to both the terminal and the logfile.
+  Set if you want debug output to go only to the log file.
+
+set style title foreground COLOR
+set style title background COLOR
+set style title intensity VALUE
+  Control the styling of titles.
+
+set style highlight foreground COLOR
+set style highlight background COLOR
+set style highlight intensity VALUE
+  Control the styling of highlightings.
+
+maint test-settings KIND
+  A set of commands used by the testsuite for exercising the settings
+  infrastructure.
+
+* Changed commands
+
+help
+  The "help" command uses the title style to enhance the
+  readibility of its output by styling the classes and
+  command names.
+
+apropos [-v] REGEXP
+  Similarly to "help", the "apropos" command also uses the
+  title style for the command names.  "apropos" accepts now
+  a flag "-v" (verbose) to show the full documentation
+  of matching commands and to use the highlight style to mark
+  the documentation parts matching REGEXP.
+
+show style
+  The "show style" and its subcommands are now styling
+  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.
+
+* New MI commands
+
+-complete
+  This lists all the possible completions for the rest of the line, if it
+  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.
+
+* Testsuite
+
+  The testsuite now creates the files gdb.cmd (containing the arguments
+  used to launch GDB) and gdb.in (containing all the commands sent to
+  GDB) in the output directory for each test script.  Multiple invocations
+  are appended with .1, .2, .3 etc.
