+* GDB now supports range stepping, which improves the performance of
+ single stepping over a source line by reducing the number of control
+ packets from GDB.

* New remote packets
QTBuffer:size
Set the size of trace buffer. The remote stub reports support for this
packet to gdb's qSupported query.
+vCont;r
+ Tell the remote stub to do range stepping in an address range. The remote
+ stub reports a stop reply when the program goes out of the range or is
+ stopped due to other reasons, such as hitting a breakpoint.
