The Lithium II Mod for Quake II page has the new version 1.24 of this Quake II mod. The new release is "finally" based on the Quake II 3.20 game source, and fixes some bugs, including one that caused version 1.23 server to crash. Lithium is one of my favorite Quake II mods, offering a bunch of features that can be toggled on or off, including: strength, resist, regen, haste, and vampire Runes, and an improved HUD offering info like your frags/hr.
