Weekly Minecraft Snapshot now available for download

After a long Christmas vacation, it seems Mojang is coming back to work. Jeb has published another Minecraft Snapshot this week. There are numerous changes, like brewing time reduced to twenty seconds, slight changes to biomes (less flat), world type options are back (only flat and default right now), new language translations, and "Updated fence gate collision box to align with fences." If this sounds great to you, the links are below to download.
