+* The $_siginfo convenience variable now also works on Windows targets,
+ and will display the EXCEPTION_RECORD of the last handled exception.
+
+* TUI windows can now be arranged horizontally.
+
+* The command history filename can now be set to the empty string
+ either using 'set history filename' or by setting 'GDBHISTFILE=' in
+ the environment. The effect of setting this filename to the empty
+ string is that GDB will not try to load any previous command
+ history.
+
+* On Windows targets, it is now possible to debug 32-bit programs with a
+ 64-bit GDB.
+
+* New commands
+
+set exec-file-mismatch -- Set exec-file-mismatch handling (ask|warn|off).
+show exec-file-mismatch -- Show exec-file-mismatch handling (ask|warn|off).
+ Set or show the option 'exec-file-mismatch'. When GDB attaches to a
+ running process, this new option indicates whether to detect
+ a mismatch between the current executable file loaded by GDB and the
+ executable file used to start the process. If 'ask', the default,
+ display a warning and ask the user whether to load the process
+ executable file; if 'warn', just display a warning; if 'off', don't
+ attempt to detect a mismatch.
+
+tui new-layout NAME WINDOW WEIGHT [WINDOW WEIGHT]...
+ Define a new TUI layout, specifying its name and the windows that
+ will be displayed.
+
+* New targets
+
+GNU/Linux/RISC-V (gdbserver) riscv*-*-linux*
+
+* Python API
+
+ ** gdb.register_window_type can be used to implement new TUI windows
+ in Python.
+
+ ** Dynamic types can now be queried. gdb.Type has a new attribute,
+ "dynamic", and gdb.Type.sizeof can be None for a dynamic type. A
+ field of a dynamic type may have None for its "bitpos" attribute
+ as well.
+
+ ** Commands written in Python can be in the "TUI" help class by
+ registering with the new constant gdb.COMMAND_TUI.
