+ removed.
+
+* Support for thread names on MS-Windows.

+
+*** Changes in GDB 7.12
+
+* GDB and GDBserver now build with a C++ compiler by default.
+
+ The --enable-build-with-cxx configure option is now enabled by
+ default. One must now explicitly configure with
+ --disable-build-with-cxx in order to build with a C compiler. This
+ option will be removed in a future release.
+
+* GDBserver now supports recording btrace without maintaining an active
+ GDB connection.
* GDB now supports a negative repeat count in the 'x' command to examine
memory backward from the given address. For example:
for its own control and synchronization, invisible to the command
line.
+* The "catch syscall" command catches groups of related syscalls.
+
+ The "catch syscall" command now supports catching a group of related
+ syscalls using the 'group:' or 'g:' prefix.
+
* New commands
skip -file file
** gdb.Breakpoint objects have a new attribute "pending", which
indicates whether the breakpoint is pending.
+ ** Three new breakpoint-related events have been added:
+ gdb.breakpoint_created, gdb.breakpoint_modified, and
+ gdb.breakpoint_deleted.
+
+signal-event EVENTID
+ Signal ("set") the given MS-Windows event object. This is used in
+ conjunction with the Windows JIT debugging (AeDebug) support, where
+ the OS suspends a crashing process until a debugger can attach to
+ it. Resuming the crashing process, in order to debug it, is done by
+ signalling an event.
* Support for tracepoints and fast tracepoints on s390-linux and s390x-linux
was added in GDBserver, including JIT compiling fast tracepoint's
=record-started,thread-group="i1",method="btrace",format="bts"
+* MI async record =thread-selected now includes the frame field. For example:
+
+ =thread-selected,id="3",frame={level="0",addr="0x00000000004007c0"}
+
