 *** Changes since GDB 7.11

+  GDB connection.

+* Support for running interpreters on specified input/output devices
+
+  GDB now supports a new mechanism that allows frontends to provide
+  fully featured GDB console views, as a better alternative to
+  building such views on top of the "-interpreter-exec console"
+  command.  See the new "new-ui" command below.  With that command,
+  frontends can now start GDB in the traditional command-line mode
+  running in an embedded terminal emulator widget, and create a
+  separate MI interpreter running on a specified i/o device.  In this
+  way, GDB handles line editing, history, tab completion, etc. in the
+  console all by itself, and the GUI uses the separate MI interpreter
+  for its own control and synchronization, invisible to the command
+  line.
