Aleph One 0.22 is available from http://source.bungie.org/get/
Highlights for this release include Lua persistence, a network stats display, and joystick support (from Eric Peterson). Jeremiah Morris has also joined us to add terminal and classic HUD scaling, as well as a new customizable HUD; and Solra Bizna added gamma-corrected alpha blending.
Jeremiah and TychoVII have also created an amazing custom HUD script based on the HUD in the XBLA game Marathon: Durandal, which you can get from Fileball: http://fileball.bungie.org/index.php?option=com_remository&Itemid=53&func=fileinfo&id=3468
Aleph One 0.22 is network compatible with the previous release, except for the new Lua features. Aleph One 0.22 is the last release which will support Mac OS X 10.2.8; future releases will require Mac OS X 10.3.9
