 *** Changes since GDB 5.3:
 
+* The meaning of "detach" has changed for gdbserver
+
+The "detach" command will now resume the application, as documented.  To
+disconnect from gdbserver and leave it stopped, use the new "disconnect"
+command.
+
+* d10v `regs' command deprecated
+
+The `info registers' command has been updated so that it displays the
+registers using a format identical to the old `regs' command.
+
+* Profiling support
+
+A new command, "maint set profile on/off", has been added.  This command can
+be used to enable or disable profiling while running GDB, to profile a
+session or a set of commands.  In addition there is a new configure switch,
+"--enable-profiling", which will cause GDB to be compiled with profiling
+data, for more informative profiling results.
+
 * Default MI syntax changed to "mi2".
 
 The default MI (machine interface) syntax, enabled by the command line
 option "-i=mi", has been changed to "mi2".  The previous MI syntax,
-"mi1", can be enabled by sepcifying the option "-i=mi1".
+"mi1", can be enabled by specifying the option "-i=mi1".
 
 Support for the original "mi0" syntax (included in GDB 5.0) has been
 removed.

 *** Changes in GDB 5.3:
 
+* GNU/Linux shared library multi-threaded performance improved.
+
+When debugging a multi-threaded application on GNU/Linux, GDB now uses
+`/proc', in preference to `ptrace' for memory reads.  This may result
+in an improvement in the start-up time of multi-threaded, shared
+library applications when run under GDB.  One GDB user writes: ``loads
+shared libs like mad''.
