* Per-inferior thread numbers.
* Breakpoint "explicit locations" (via CLI and GDB/MI).
* New convenience variables ($_gthread, $_inferior).
* Record btrace now supports non-stop mode.
* Various improvements on AArch64 GNU/Linux:
- Multi-architecture debugging support.
- displaced stepping.
- tracepoint support added in GDBserver.
* In Ada, the overloads selection menu provides the parameter
types and return types for the matching overloaded subprograms.
* Various remote protocol improvements, including several
new packets which can be used to support features such as
follow-exec-mode, exec catchpoints, syscall catchpoints, etc.
* Some minor improvements in the Python API for extending GDB.
