Beta
Minecraft officially enters beta with the 1.0 update. The price increases from €9.95 to €14.95 (about $14 to $20). The beta 1.0 update mostly consists of minor bug fixes but also includes a patch for an inventory duplication glitch that existed previously.
Well, holy moly, beta is out. We'll update the website and increase the price now. 😀
