The current available Beta download says it’s expired as soon as you try to open it. Also if you opt to open the release notes they are shown as from 6.1.
Here is a response from Keely Chen @ Dell regarding my inquiry about dropping a new beta:
For Beta, we may not to post a new beta version till we add some new functionality . But I don’t know the exactly time for next new Beta either.
I’m so… sorry for this.
So I guess we do nothing until they post a new version which sounds like they are not sure when that will happen.
Then why do they continue to let people download a beta version that’s already expired?
And all they have to do is change the expiration date and post it again and let users keep finding bugs.
But hey, what do I know…
