ℹ️  Tip: if you want a nice short link to a changelog entry use<version>


  • 1.0 "Bloody Gobblers!": Initial release. Game ported to SDL, OpenGL, OpenAL and the amd64 architecture while maintaining native Direct X backends. Fixes some performance issues with newer operating systems, adds more configuration options and improves the interface scaling for widescreen resolutions. (announcement)
    • 1.0.1: Fixes text rendering bug in 1.0 that breaks the Russian version, a crash on some Linux systems and uses DirectX by default for rendering and input under Windows. You can still select the renderer in the video settings and if you set it to anything other than the default "Auto-Select" nothing will change for you. (announcement)
    • 1.0.2: Fixes various crashes, disappearing items when sorting the inventory, and minor rendering and input bugs. This release also fixes a bug that left the Spanish version with no text. (announcement)
    • 1.0.3: Fixes two regressions introduced in 1.0.2 for Windows users: Crashes on startup after selecting the OpenGL renderer and low mouse sensitivity with the DirectInput backend. There are also fixes for other crashes, rendering glitches, missing speech during cinematics in the Russian and Italian versions, missing ambient sound effects as well as bugs in how some skill values were calculated. (announcement)
  • 1.1 "Rhaa Movis": Fixes player movement issues, minimap scaling, and a bunch of crashes and other bugs. We also continued our work on restructuring the engine, to facilitate new features in the future. Further, there is an improved installer for the data files on *nix systems as well as minor graphics and sound tweaks. See the changelog for full details. While we haven't managed to include everything originally planned for 1.1, we felt it was high time for another release after nearly a year of development since 1.0.3. (announcement)
    • 1.1.1: This release is a hotfix addressing a regression introduced in 1.1, that caused map markers to not be saved correctly and then removed when such a save is loaded. We encourage all users of Arx Libertatis 1.1 to upgrade to 1.1.1 as soon as possible. (announcement)
    • 1.1.2: This is another small hotfix, this time to fix a crash when hovering over map markers after the window size or resolution has changed. (announcement)
  • 1.2 "Mega Mega Mega": This release brings improved rune recognition when casting spells, as well as a new bow aim mode. Support for high resolutions and wide monitors is enhanced with configurable HUD and player book scaling. The text and audio language can now be changed in the menu. Further, item physics have been fixed and item dragging has been refined. On top of that, this release adds a console to execute arbitrary script commands. (announcement)
    • 1.2.1: This release is a hotfix addressing an unintended change to the calculation of the player armor class as well as poison and magic resistance. It also restores death screams which were missing for most NPCs and fixes issues with using stacks of potions by dropping them on the player book and fixes number of crashes, performance issues and bugs. This release also restores Windows XP support for the official binaries. (announcement)
