 * New system-wide configuration scripts
   A GDB installation now provides scripts suitable for use as system-wide
   configuration scripts for the following systems:
     ** ElinOS
     ** Wind River Linux
 
+* GDB now supports target-assigned range stepping with remote targets.
+  This improves the performance of stepping source lines by reducing
+  the number of control packets from/to GDB.  See "New remote packets"
+  below.
+
+* GDB now understands the element 'tvar' in the XML traceframe info.
+  It has the id of the collected trace state variables.
+
+* New remote packets
+
+vCont;r
+
+  The vCont packet supports a new 'r' action, that tells the remote
+  stub to step through an address range itself, without GDB
+  involvemement at each single-step.

+qXfer:libraries-svr4:read's annex
+  The previously unused annex of the qXfer:libraries-svr4:read packet
+  is now used to support passing an argument list.  The remote stub
+  reports support for this argument list to GDB's qSupported query.
+  The defined arguments are "start" and "prev", used to reduce work
+  necessary for library list updating, resulting in significant
+  speedup.
+
+* New features in the GDB remote stub, GDBserver
+
+  ** GDBserver now supports target-assisted range stepping.  Currently
+     enabled on x86/x86_64 GNU/Linux targets.
+
+  ** GDBserver now adds element 'tvar' in the XML in the reply to
+     'qXfer:traceframe-info:read'.  It has the id of the collected
+     trace state variables.
+
+  ** GDBserver now supports hardware watchpoints on the MIPS GNU/Linux
+     target.
