Commit is being made to allow additions of GPL3+ code previously un-addable. With these changes, contributions back to cuberite are possible with the backporting exemtion, as well as adding stuff in minetest with minetest code properly being read through and implimented to upgrade it to GPL3 from GPL2. project still has Apache2.0 license and credits to all its contributers, but now has the freedom of GPL3+ and all the code that can be implimented and shared with it.
