The snapshot allows experienced Minecraft players to test out new features before they are released in a normal update. Jens posted on the Mojang website the details of the snapshot:
- Anvil block has been tweaked (it’s cheaper to create, minor visual changes, and you can repair tools using wood/ingots/diamonds)
- Bats no longer trample crops or trigger pressure plates
- Redstone repeaters can be “locked” (fixed output) by having a powered repeater connected to its left or right side
- Added an option to hide a server’s IP address
- Updated language files
- More bugfixes & tweaks!
So if you want to try out the latest Minecraft content before most players head over to the Mojang website now to download the snapshot.
