+* When the Text User Interface (TUI) is not configured, GDB will now
+recognize the -tui command-line option and print a message that the TUI
+is not supported.

* The GDB remote stub, gdbserver, now has lower overhead for high
frequency signals (e.g. SIGALRM) via the QPassSignals packet.

* GDB and the GDB remote stub, gdbserver, now support the XScale
iWMMXt coprocessor.
ARM Windows CE (mingw32ce) debugging, and GDB Windows CE support
has been rewritten to use the standard GDB remote protocol.
+* GDB can now step into C++ functions which are called through thunks.
+
+* GDB for the Cell/B.E. SPU now supports overlay debugging.
+
+* The GDB remote protocol "qOffsets" packet can now honor ELF segment
+layout. It also supports a TextSeg= and DataSeg= response when only
+segment base addresses (rather than offsets) are available.
+
+* The /i format now outputs any trailing branch delay slot instructions
+immediately following the last instruction within the count specified.

* New commands
+set remoteflow
+show remoteflow
+ Enable or disable hardware flow control (RTS/CTS) on the serial port
+ when debugging using remote targets.

general version of "set solib-absolute-prefix", which is now
an alias to "set sysroot".
