Just setting expectation here...
The update will be the biggest update to RHP since its inception, but it does not bring new features (nothing not UI related anyway).
-This is primarily new board code (it will still look the same and function as before, but will also support drag and drop. It is a total re-write.)
-We are trying to address the shift to tablets. There is still a lot to decide here, and almost certaintiy not all the changes will please everyone.
The Beta period will take as long as it takes, but I would hope to get quite a wide sample of users due to the nature of the large update. (and risks associated with a release of such a size.) A beta is not available yet, this is still ongoing work. And it is taking way longer than expeceted...!
