According to Notch the latest patch will be delayed until next week “There’s been significant feature creep (we’ve got powered rails now, and lightning hitting a pig will turn it into a zombie pigman), so we don’t have time to get it out this week.” So people waiting for the latest patch which includes weather, stats and achievements will have to wait a bit longer.

First tameable wolves, now achievments and weather? I love this game.
Still excited for the update, possibly more so with all the features that are supposed to be included!
