*** Changes since GDB-4.18:
+* Remote targets can connect to a sub-program
+
+A popen(3) style serial-device has been added. This device starts a
+sub-process (such as a stand-alone simulator) and then communicates
+with that. The sub-program to run is specified using the syntax
+``|<program> <args>'' vis:
+
+ (gdb) set remotedebug 1
+ (gdb) target extended-remote |mn10300-elf-sim program-args
+
* New targets
TI TMS320C80 tic80-*-*
Convex c1-*-*, c2-*-*
Pyramid pyramid-*-*
+* MIPS 64 remote protocol
+
+A long standing bug in the mips64 remote protocol where by GDB
+expected certain 32 bit registers (ex SR) to be transfered as 32
+instead of 64 bits has been fixed.
+
+The command ``set remote-mips64-transfers-32bit-regs on'' has been
+added to provide backward compatibility with older versions of GDB.
+
