This is considered ‘beta 2’. It fixes the main bugs which we have been able to reproduce so far. The list of fixes is here: http://wiki.micasaverde.com/index.php/Release_Notes
Many thanks to the 200 beta testers who signed up the past 2 weeks and contributed their findings. It is a great help flushing out these issues.
There are still some lingering issues which we have not yet been able to reproduce. We expect to offer a beta 3 release in approximately 1 week which fixes all known bugs in the web ui, portal and basic operation. At that point we will shift the focus to improving compatibility with Z-Wave devices and other Z-Wave related changes needed for certification in anticipation of our first certified, mainstream release.
