 *** Changes since GDB 8.0
 
+* GDB now uses the GNU MPFR library, if available, to emulate target
+  floating-point arithmetic during expression evaluation when the target
+  uses different floating-point formats than the host.  At least version
+  3.1 of GNU MPFR is required.
+
+* GDB now supports access to the guarded-storage-control registers and the
+  software-based guarded-storage broadcast control registers on IBM z14.
+
 * On Unix systems, GDB now supports transmitting environment variables
   that are to be set or unset to GDBserver.  These variables will
   affect the environment to be passed to the remote inferior.

+  ** A new command, "rbreak" has been added to the Python API.  This
+     command allows the setting of a large number of breakpoints via a
+     regex pattern in Python.  See the manual for further details.
+
 * New features in the GDB remote stub, GDBserver
 
+  ** GDBserver is now able to start inferior processes with a
+     specified initial working directory.
+
+     The user can set the desired working directory to be used from
+     GDB using the new "set cwd" command.
+
   ** New "--selftest" command line option runs some GDBserver self
      tests.  These self tests are disabled in releases.
