 - Added :meth:`flask.Flask.app_context` which works very similar to the
   request context but only provides access to the current application.  This
   also adds support for URL generation without an active request context.
-
+- View functions can now return a tuple with the first instance being an
+  instance of :class:`flask.Response`.  This allows for returning
+  ``jsonify(error="error msg"), 400`` from a view function.
+- :class:`flask.Flask` now provides a `get_send_file_options` hook for
+  subclasses to override behavior of serving static files from Flask when using
+  :meth:`flask.Flask.send_static_file` based on keywords in
+  :func:`flask.helpers.send_file`.  This hook is provided a filename, which for
+  example allows changing cache controls by file extension.  The default
+  max-age for `send_static_file` can be configured through a new
+  ``SEND_FILE_MAX_AGE_DEFAULT`` configuration variable, regardless of whether
+  the `get_send_file_options` hook is used.
+- Fixed an assumption in sessions implementation which could break message
+  flashing on sessions implementations which use external storage.
