That’s a lot of numbers, but now Minecraft 1.7.6 pre-release is available for testing! This is a huge step towards one of the most requested features since the birth of Minecraft: Name changes! This version provides complete support for identifying players through unique IDs and not by names, so that no matter what a player is called they will remain banned/whitelisted/oped/etc on servers.
To get pre-releases, open your launcher and press the “New Profile” button. Call it “pre-releases” and check the box saying “Enable experimental development snapshots”, select the version from the dropdown and save. To switch to the normal version, you can select it in the dropdown at the bottom left corner of the launcher. Back up your world first or run the game on in a different folder (See the “new profile” dialog).
Snapshots and pre-releases can corrupt your world, please backup and/or run them in a different folder from your main worlds.
