-WorldEnvironment cleanup issues fixed (#563) -Text Editor improvement to shift-mouse selection (#648) -(Hopefully) fixed rare (but horrible) indexing bug in GDScript compiler (#652) -Some changes to PhysicsBody API, renamed property "active" to "sleeping", which makes more sense -Added add_collision_exception() API in PhysicsBody (more accessible) -ability to select and copy in the output messages panel
