-fixed TouchScreenButton with stretch2d -fixed(?) OSX crash on startup (test!!) -compilation fixes on windows -CollisionPolygon editor works again -find buttons en find dialog -TileMap editor cleanup (removed "error", made nicer) -viewport flicker fixed -make .scn default extension for saving scenes -export the rest of the network classes to gdscript
