Skins version 2 are pretty stable starting at version 2.1.
Note: In real life Monument Valley is actually located on the border between Utah and Arizona. Not really in Nevada. Just so you know... :P
Plugins from 1.10 will generally work with this version.
Skins from 1.10 need some changes (upgrade instructions). NOTE: the 2.0 skintags are not final yet!
Skins from 1.9 can be used in this version.
Skins from 1.8 can be used in this version.
Skins from 1.6 will need some changes.
Skins from 0.x will need some changes.
The main focus of this new version was to remove the b2 legacy code from the evoCore framework in order to move to a more stable, reliable and scalable architecture (with Objects and all the rest...). This was mostly behind the scenes work without immediate features to show off for gratification. However, the new evoCore now allows to add functionnality more quickly and more efficiently.
Anyway, there are already quite a few new features available:
var $display = false;
to var $display = true;
