   INTERNALS:
 
+    * Default User Interface (UI) is CLIUIFactory when bzr runs in a dumb
+      terminal. It is sometimes desirable do override this default by forcing
+      bzr to use TextUIFactory. This can be achieved by setting the
+      BZR_USE_TEXT_UI environment variable (emacs shells, as opposed to
+      compile buffers, are such an example).
+      (Vincent Ladeuil)
+
     * ``TreeDelta.show()`` now accepts a ``filter`` parameter allowing log
       formatters to retrict the output.
