Just spotted over at Doomworld that the latest version of the Eternity Engine has released around Christmas. There is a long list of changes with numerous improvements, fixes and new features that are worth checking out - not only in a player's perspective. This update also features some EDF improvements, some more steps toward Hexen support, various bug fixes, further improvements to compatibility, and even more speed optimizations. Downloads, more information, and a full readme text can be found in the release thread in the Eternity subforum, just as usual. And if you are too keen to wait, just pick v3.40.20 "Mjolnir" here. Might be a good moment to play the Vaporware demo again...
