You'd see a Beta Testing forum. In there are instructions for how to download via our Subversion repository. There have been no public releases from 1.0E, mainly because the mod has added two completely new races. This requires a lot of polish and retweaking of many areas of the mod. Lavo, sloosecannon, and others have done a large amount of work. I don't think you'll see a public release until it's done. The reason to get beta testers is to report issues, make suggestions, do playtesting, even contribute where possible. It is really the people in this community putting their free time and effort into it. So say thank you to those people, and, if you find time to contribute - please do so with your feedback.
