New 3D effects like Fog; Improved Android keyboard handling; Bug fixes.
Ashley, I'm not sure how that's supposed to work.
Its third party.
As others have mentioned this version appears to introduce a breaking change affecting ALL custom plugins.
3rd party addons register using class.Register(), but now they need to use class.prototype.Register() instead.
File an issue anyway including the exact version of the affected addon you're using and we'll look in to it. We don't want any accidental regressions for third-party addons.
