GNOME 3.11.4 now depends on GTK+ 3.10, removes the fullscreen mode, uses symbolic icons in the bottom bar, adds a “linked” style to the navigation buttons, uses a symbolic light bulb in the Preferences dialog, removes the extra space between Black and White timers, and it no longer automatically pauses the game when the user views the menu or switches windows. Moreover, GtkToolbar has been replaced with GtkMenuButton and GtkHeaderBar, the pause key has been transformed into an accelerator for the resume and pause actions, better error messages are now displayed when something wrong happens with the chess engine, and it will no longer display false error messages about engine crashes that did not happen.
