 *** Changes since GDB 8.2
 
+* GDB now has experimental support for the compilation and injection of
+  C++ source code into the inferior.  This beta release does not include
+  support for several language features, such as templates, constructors,
+  and operators.
+
+  This feature requires GCC 7.1 or higher built with libcp1.so
+  (the C++ plug-in).
+
 * GDB and GDBserver now support IPv6 connections.  IPv6 addresses
   can be passed using the '[ADDRESS]:PORT' notation, or the regular
   'ADDRESS:PORT' method.
 
+* DWARF index cache: GDB can now automatically save indices of DWARF
+  symbols on disk to speed up further loading of the same binaries.
+
+* GDB in batch mode now exits with status 1 if the last command to be
+  executed failed.
+
+* Changes to the "frame", "select-frame", and "info frame" CLI
+  commands.  These commands all now take a frame specification which
+  is either a frame level, or one of the keywords 'level', 'address',
+  'function', or 'view' followed by a parameter.  Selecting a frame by
+  address, or viewing a frame outside the current backtrace now
+  requires the use of a keyword.  Selecting a frame by level is
+  unchanged.  The MI comment "-stack-select-frame" is unchanged.
+
 * New commands
 
+set debug compile-cplus-types
+show debug compile-cplus-types
+  Control the display of debug output about type conversion in the
+  C++ compile feature.  Commands have no effect while compiliong
+  for other languages.
+
+set debug skip
+show debug skip
+  Control whether debug output about files/functions skipping is
+  displayed.

 * Changed commands
 
+target remote FILENAME
+target extended-remote FILENAME
+  If FILENAME is a Unix domain socket, GDB will attempt to connect
+  to this socket instead of opening FILENAME as a character device.
+
 thread apply [all | COUNT | -COUNT] [FLAG]... COMMAND
   The 'thread apply' command accepts new FLAG arguments.
   FLAG arguments allow to control what output to produce and how to handle
   errors raised when applying COMMAND to a thread.
 
+* MI changes
+
+  ** The '-data-disassemble' MI command now accepts an '-a' option to
+     disassemble the whole function surrounding the given program
+     counter value or function name.  Support for this feature can be
+     verified by using the "-list-features" command, which should
+     contain "data-disassemble-a-option".
+
+  ** Command responses and notifications that include a frame now include
+     the frame's architecture in a new "arch" attribute.
+
+* New native configurations

+  ** The gdb.Inferior type has a new 'progspace' property, which is the program
+     space associated to that inferior.
+
+  ** The gdb.Progspace type has a new 'objfiles' method, which returns the list
+     of objfiles associated to that program space.
