* GDB and GDBserver now support access to additional registers on
PowerPC GNU/Linux targets: PPR, DSCR, TAR, EBB/PMU registers, and
* GDB in batch mode now exits with status 1 if the last command to be
executed failed.
-* Changes to the "frame", "select-frame", and "info frame" CLI
- commands. These commands all now take a frame specification which
- is either a frame level, or one of the keywords 'level', 'address',
- 'function', or 'view' followed by a parameter. Selecting a frame by
- address, or viewing a frame outside the current backtrace now
- requires the use of a keyword. Selecting a frame by level is
- unchanged. The MI comment "-stack-select-frame" is unchanged.
-
* The RISC-V target now supports target descriptions.
* System call catchpoints now support system call aliases on FreeBSD.

* MI changes
+ ** The default version of the MI interpreter is now 3 (-i=mi3).

** The '-data-disassemble' MI command now accepts an '-a' option to
disassemble the whole function surrounding the given program
counter value or function name. Support for this feature can be
** Command responses and notifications that include a frame now include
the frame's architecture in a new "arch" attribute.
+ ** The output of information about multi-location breakpoints (which is
+ syntactically incorrect in MI 2) has changed in MI 3. This affects
+ the following commands and events:
+
+ - -break-insert
+ - -break-info
+ - =breakpoint-created
+ - =breakpoint-modified
+
+ The -fix-multi-location-breakpoint-output command can be used to enable
+ this behavior with previous MI versions.
