Sorry, I totally missed your post.
The easiest way to follow development is via Github: https://github.com/Mark-H/VersionX2
I've been having some great help from Adam Lundrigan, but unfortunately am totally swamped right now to get his latest development work pulled in and finishing the last bits before I'm uploading it.
I'm going to stop giving out release dates for open source projects: they all seem perfect when you set them, but end up being impossible to hit.
You can get the latest copy from Git as well, in the _packages dir I keep the latest builds: https://github.com/Mark-H/VersionX2/tree/master/_packages
- it may be alpha, but already employing it in many sites myself and works great so far.
