[Switching to thread 2.1 (Thread 0x7ffff7fc2740 (LWP 8157))] (running)
(gdb)
+* In commands that accept a list of thread IDs, you can now refer to
+ all threads of an inferior using a star wildcard. GDB accepts
+ "INF_NUM.*", to refer to all threads of inferior INF_NUM, and "*" to
+ refer to all threads of the current inferior. For example, "info
+ threads 2.*".
+
* You can use "info threads -gid" to display the global thread ID of
all threads.
* The new convenience variable $_inferior holds the number of the
current inferior.
+* GDB now displays the ID and name of the thread that hit a breakpoint
+ or received a signal, if your program is multi-threaded. For
+ example:
+
+ Thread 3 "bar" hit Breakpoint 1 at 0x40087a: file program.c, line 20.
+ Thread 1 "main" received signal SIGINT, Interrupt.
+
* Record btrace now supports non-stop mode.
* Support for tracepoints on aarch64-linux was added in GDBserver.
