 *** Changes since GDB 7.3
 
 
 *** Changes since GDB 7.3
 

+* GDB has two new commands: "set remote hardware-watchpoint-length-limit"
+  and "show remote hardware-watchpoint-length-limit".  These allows to
+  set or show the maximum length limit (in bytes) of a remote
+  target hardware watchpoint.
+
+  This allows e.g. to use "unlimited" hardware watchpoints with the
+  gdbserver integrated in Valgrind version >= 3.7.0.  Such Valgrind
+  watchpoints are slower than real hardware watchpoints but are
+  significantly faster than gdb software watchpoints.
+
+* Python scripting
+
+  ** The "maint set python print-stack on|off" command has been
+     deprecated, and a new command: "set python print-stack on|off" has
+     replaced it.  Additionally, the default for "print-stack" is now
+     "off".
+   
+  ** A prompt subsitution hook (prompt_hook) is now available to the
+     Python API.
+
+* libthread-db-search-path now supports two special values: $sdir and $pdir.
+  $sdir specifies the default system locations of shared libraries.
+  $pdir specifies the directory where the libpthread used by the application
+  lives.
+
+  GDB no longer looks in $sdir and $pdir after it has searched the directories
+  mentioned in libthread-db-search-path.  If you want to search those
+  directories, they must be specified in libthread-db-search-path.
+  The default value of libthread-db-search-path on GNU/Linux and Solaris
+  systems is now "$sdir:$pdir".
+
+  $pdir is not supported by gdbserver, it is currently ignored.
+  $sdir is supported by gdbserver.
+
+* New configure option --with-iconv-bin.
+  When using the internationalization support like the one in the GNU C
+  library, GDB will invoke the "iconv" program to get a list of supported
+  character sets.  If this program lives in a non-standard location, one can
+  use this option to specify where to find it.
+

 * When natively debugging programs on PowerPC BookE processors running
   a Linux kernel version 2.6.34 or later, GDB supports masked hardware
   watchpoints, which specify a mask in addition to an address to watch.

+* New commands "info macros", and "info definitions" have been added.

 * Changed commands
 
 watch EXPRESSION mask MASK_VALUE
   The watch command now supports the mask argument which allows creation
   of masked watchpoints, if the current architecture supports this feature.

+info auto-load-scripts [REGEXP]
+  This command was formerly named "maintenance print section-scripts".
+  It is now generally useful and is no longer a maintenance-only command.
+
+* Tracepoints can now be enabled and disabled at any time after a trace
+  experiment has been started using the standard "enable" and "disable"
+  commands.  It is now possible to start a trace experiment with no enabled
+  tracepoints; GDB will display a warning, but will allow the experiment to
+  begin, assuming that tracepoints will be enabled as needed while the trace
+  is running.
+
+* New remote packets
+
+QTEnable
+  
+  Dynamically enable a tracepoint in a started trace experiment.
+
+QTDisable
+
+  Dynamically disable a tracepoint in a started trace experiment.
+
+* Dcache size (number of lines) and line-size are now runtime-configurable
+  via "set dcache line" and "set dcache line-size" commands.
