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.
Some of the new stuff in 1.1.10: Bright cursor, custom resolution set to follow the desktop, nicer loading screen quotes, skipping missions. New in Minimalist: Playstyle restrictions now shown in the briefing, non-silent creep, classic HUD with optional original health bar and lightgem, optional arrow trails.
