Uh oh. I think this updated automatically from the repo which is fine.
I have custom main menu items. Selecting them slide opens the custom submenu now. In the past if I selected a main menu item and pressed 'enter' it opened the main menu item such as 'Movies' or 'Settings'. Now if I select a main menu item it just opens the submenu. The submenu item opens but the main menu does not. I am locked out of my main menu 'Settings' and can't change anything without access. I'm also locked out of my 'Movies' and TV folders since they have submenus.

Any main menu item without a submenu opens correctly fwiw.

Weather widget, the only widget I use, displays nothing but blank rectangle boxes.

I have no choice but to completely rebuild, understandable with a beta build. Maybe I can alter something in the guisettings.xml but a quick glance tells me.... nope.
I take it there have indeed been some major changes and welcome them despite the setback. Something this drastic should probably be rebuilt from scratch anyway.
Just bringing 1st observation to the table and many thanks to marcelveldt for the dedication. Can't wait to rebuild and see what you've given us!
Thanks again and will report back with any quirks after installing.
