 *** Changes since GDB 6.6
 
-* New targets
-
-Cell Broadband Engine SPU      spu-elf
-
 * The GDB remote stub, gdbserver, now has lower overhead for high 
 frequency signals (e.g. SIGALRM) via the QPassSignals packet.
 
+* GDB for MIPS targets now autodetects whether a remote target provides
+32-bit or 64-bit register values.
+
+* Support for C++ member pointers has been improved.
+
+* GDB now understands XML target descriptions, which specify the
+target's overall architecture.  GDB can read a description from
+a local file or over the remote serial protocol.
+
+* Arrays of explicitly SIGNED or UNSIGNED CHARs are now printed as arrays
+  of numbers.
+
+* New commands
+
+set mem inaccessible-by-default
+show mem inaccessible-by-default
+  If the target supplies a memory map, for instance via the remote
+  protocol's "qXfer:memory-map:read" packet, setting this variable
+  prevents GDB from accessing memory outside the memory map.  This
+  is useful for targets with memory mapped registers or which react
+  badly to accesses of unmapped address space.
+
+set breakpoint auto-hw
+show breakpoint auto-hw
+  If the target supplies a memory map, for instance via the remote
+  protocol's "qXfer:memory-map:read" packet, setting this variable
+  lets GDB use hardware breakpoints automatically for memory regions
+  where it can not use software breakpoints.  This covers both the
+  "break" command and internal breakpoints used for other commands
+  including "next" and "finish".
+
+catch exception
+catch exception unhandled
+  Stop the program execution when Ada exceptions are raised.
+
+catch assert
+  Stop the program execution when an Ada assertion failed.
+
+set sysroot
+show sysroot
+  Set an alternate system root for target files.  This is a more
+  general version of "set solib-absolute-prefix", which is now
+  an alias to "set sysroot".
+
+* New native configurations
+
+OpenBSD/sh                     sh*-*openbsd*
+
+set tdesc filename
+unset tdesc filename
+show tdesc filename
+  Use the specified local file as an XML target description, and do
+  not query the target for its built-in description.
+
+* New targets
+
+OpenBSD/sh                     sh*-*-openbsd*
+MIPS64 GNU/Linux (gdbserver)   mips64-linux-gnu
+
 * New remote packets
 
 QPassSignals:
   Ignore the specified signals; pass them directly to the debugged program
   without stopping other threads or reporting them to GDB.
 
+qXfer:features:read:
+  Read an XML target description from the target, which describes its
+  features.

 * The "set trust-readonly-sections" command works again.  This command was
 broken in GDB 6.3, 6.4, and 6.5.
 
+* The "load" command now supports writing to flash memory, if the remote
+stub provides the required support.
+
 * Support for GNU/Linux Thread Local Storage (TLS, per-thread variables) no
 longer requires symbolic debug information (e.g. DWARF-2).
