We've started our open beta release. See the post here
We will put it on our main download page when it gets a bit further through the beta QA process. This is an early release.
Note that this is still a very early beta and there's lots to fix. In particular, we need to correct some issues with the visualization and the EUE handling. However, we've got that in our roadmap and should be rolling that out over the next few weeks or so (hopefully sooner, but it may be longer depending on how tricky these bugs are to handle).
If this release looks to run well for most people, we'll put it on our main download page.
