Minecraft Snapshot 14w28a has been released. Todays snapshot is one such example, bringing (hopefully) some big optimizations to the server and client, a few less bugs to worry about, and a handful of hugs in their place.
To get snapshots, open your launcher and press the “New Profile” button. Call it “snapshots” and check the box saying “Enable experimental development snapshots” 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 can corrupt your world, please backup and/or run them in a different folder from your main worlds.
