Data-read watchpoints on x86 targets no longer erroneously trigger when the address is written. It is possible to catch signals that happened in the debuggee, deliver signals to it, interrupt it with Ctrl-C, etc. Interrupting GDB with Ctrl-C also works. Gould support removed Support for the Gould PowerNode and NP1 has been removed. Overload resolution now works properly in almost all cases.
RTTI support is on the way.
64 bits has been fixed. Breakpoint commands accept ranges. This interface is designed for debug environments running GDB as a separate process. This is part of the long term libGDB project.
