Also, keep in mind that once 2.x is finished and we move to 3.0, it is likely that all versions of 2.x other than the final version will be removed, just like with other versions of the game. So if you are using a mod that prevents you from updating the game, it would be a good idea to try to get that mod updated so that it will work in newer versions before all other 2.x versions get removed in the future.
