From the announcement:
Cumberland Games releases the 20th Anniversary (version 2.0) edition of one of the longest-running free RPGs in the world, Risus: The Anything RPG. The new edition comes in several formats, including PDF, ePub, and two different single-sheet pamphlet-folding styles. It's also down to 4 pages long (instead of 6), making it one of the only RPGs to get smaller in a second edition.
