The patch contains various bugfixes and game improvements such as widescreen support, and provides some GUI tweaks. It also enables the use of the FMSel fan mission loader frontend with Thief 3 and bundles the most important T3 mods. It works with the GOG and Steam versions of the game.
New in 1.1.11 / T3G 1.4: Each merged mission map has been divided into sections corresponding to the two original half-maps. This makes it possible to use all the original map titles, savegame titles and loading screens according to the player's location in the map.
