The three (so far) clients for reLive are getting constant updates from their authors becker, Floaf and Gulrak. The latest in the row to get some major updates is the Windows client by Floaf. In its v0.19 it has gotten a bunch of bug fixes as well as an auto-updater and the chatlog word wrapping. It now also has an installer, if you're not pleased with only using the .exe itself.
