 * [#1278](https://github.com/bbatsov/prelude/issues/1278): Don't disable `menu-bar-mode` unless `prelude-minimalistic-ui` is enabled.
 * [#1277](https://github.com/bbatsov/prelude/issues/1277): Make it possible to disable the creation of `Super`-based keybindings via `prelude-super-keybindings`.
 * Removed deprecated alias `prelude-ensure-module-deps`.
+* Remove `prelude-fullscreen`, as these days people can use `toggle-frame-fullscreen` instead. (it was introduced in Emacs 24.4)
