Update for anyone downloading the latest version. Was getting frustrated trying to find this info so thought Id post it now that I found it.
- The Alt + left click no longer works to rotate your 'canvas' unless you use 'simulate third mouse button' in settings. Otherwise you use your middle mouse button to rotate.
- To get mirror working it will be on the right panel, now on the bottom, the bottom is now for your animation.
- k is no longer loop cut, search loop cut in your settings to change this, also it doesn't knife cut the same, maybe there is another button? not sure. If you know let me know

Other than that i haven't found much difference so far for how far along I am.
