                What has changed in GDB?
             (Organized release by release)
 
-*** Changes since GDB 7.8
+*** Changes since GDB 7.9
+
+* The "info source" command now displays the producer string if it was
+  present in the debug info.  This typically includes the compiler version
+  and may include things like its command line arguments.
+
+* Python Scripting
+
+  ** gdb.Objfile objects have a new attribute "username",
+     which is the name of the objfile as specified by the user,
+     without, for example, resolving symlinks.
+
+* New commands
+
+maint print symbol-cache
+  Print the contents of the symbol cache.
+
+maint print symbol-cache-statistics
+  Print statistics of symbol cache usage.
+
+maint flush-symbol-cache
+  Flush the contents of the symbol cache.
+
+record btrace bts
+record bts
+  Start branch trace recording using Branch Trace Store (BTS) format.
+
+* New options
+
+set max-completions
+show max-completions
+  Set the maximum number of candidates to be considered during
+  completion.  The default value is 200.  This limit allows GDB
+  to avoid generating large completion lists, the computation of
+  which can cause the debugger to become temporarily unresponsive.
+
+maint set symbol-cache-size
+maint show symbol-cache-size
+  Control the size of the symbol cache.
+
+set|show record btrace bts buffer-size
+  Set and show the size of the ring buffer used for branch tracing in
+  BTS format.
+  The obtained size may differ from the requested size.  Use "info
+  record" to see the obtained buffer size.
+
+* The command 'thread apply all' can now support new option '-ascending'
+  to call its specified command for all threads in ascending order.
+
+* Python/Guile scripting
+
+  ** GDB now supports auto-loading of Python/Guile scripts contained in the
+     special section named `.debug_gdb_scripts'.
+
+* New remote packets
+
+qXfer:btrace-conf:read
+  Return the branch trace configuration for the current thread.
+
+Qbtrace-conf:bts:size
+  Set the requested ring buffer size for branch tracing in BTS format.
+
+* The info record command now shows the recording format and the
+  branch tracing configuration for the current thread when using
+  the btrace record target.
+  For the BTS format, it shows the ring buffer size.
+
+* GDB now has support for DTrace USDT (Userland Static Defined
+  Tracing) probes.  The supported targets are x86_64-*-linux-gnu.
+
+*** Changes in GDB 7.9
 
 * GDB now supports hardware watchpoints on x86 GNU Hurd.
