Version 1.7.8 is now officially released. This version contains some bugfixes, a few updates to make Realms even better than it already is and prepares Minecraft for the renaming feature that will eventually allow you to rename your player. The renaming feature will not be available right now, but this is an important step towards it. We have also changed the internal handling of player skins to make use of our new, improved skin servers.
