+maint check-symtabs
+  Perform consistency checks on symtabs.
+maint expand-symtabs
+  Expand symtabs matching an optional regexp.

 * Newly installed $prefix/bin/gcore acts as a shell interface for the
   GDB command gcore.
 
+* GDB now implements the the C++ 'typeid' operator.
+
+* The new convenience variable $_exception holds the exception being
+  thrown or caught at an exception-related catchpoint.
+
+* The exception-related catchpoints, like "catch throw", now accept a
+  regular expression which can be used to filter exceptions by type.
+
 * MI changes
 
   ** The -trace-save MI command can optionally save trace buffer in Common
      Trace Format now.
 
+  ** The new command -dprintf-insert sets a dynamic printf breakpoint.
+
+  ** The command -data-list-register-values now accepts an optional
+     "--skip-unavailable" option.  When used, only the available registers
+     are displayed.
+
+  ** The new command -trace-frame-collected dumps collected variables,
+     computed expressions, tvars, memory and registers in a traceframe.
+
+* 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.
+
+* New 'z' formatter for printing and examining memory, this displays the
+  value as hexadecimal zero padded on the left to the size of the type.

 *** Changes in GDB 7.6
 
 * Target record has been renamed to record-full.
