That's right, release *FOUR*. I guess we've been forgotten about by ReneX's Public Relations team, oh well.
Check out the new stuff here (dunno what was in release two and three):
http://www.moddb.com/mods/renegade-x/news/renegade-x-05-beta-releaseAlso take note that it's the Mod DB Mod Of The Year awards. Both First Strike and RenX have made it to the top 100 and need votes, so if you could *please* make a ModDB account (Guest votes only are counted if there is a tie between two mods, very unlikley with thousands of voters) and vote for both RenX and First Strike it would be greatly appreciated!
VOTE LINKEDIT: On related news, Epic (is it Epic???) released the development kit for the UT engine for free use, so soon we'll see RenX as a full game, not just a mod, as it ports over to use that instead of basing everything from UT3.
