Minecraft creator Mojang Specifications' unswerving work ethic. The developer launched Beta Update 1.6 for the world-building title yesterday, adding mapmaking, hatches, some new vegetation and multiplayer Nether functionality to the title. Unfortunately, the update also added a handful of nasty bugs and performance problems into the game -- problems which Mojang managed to fix by releasing four subsequent mini-patches in the very same day.
You can check out all of the game's latest patch notes after the jump, including patches 1.6.1 through 1.6.4. We suggest reading them in order, like a short story that was really, really frustrating for the author to write.
