This week's snapshot doesn't have any new mobs, but it does include some nifty additions. First, many bug fixes relating to mobs, probably mobs with the new AI. Ocelots, the mob added in last week's snapshot, are now easier to tame and can sit. Villagers will now stay in their houses and not roam the land around them like pigs. The language files were also updated with, "with 50% less profanities," referring to the racist comment found in last week's snapshot. Lastly, a host of bugfixes have been added to this release, as always. You can download the jar files below.
