Two weeks after spoiling some changes for Minecraft on Title Update 12, 4J Studios have finally released a full list of changes. As we have covered before, these changes are more focused on adding brand new content, although it turns out they still had to add some fixes anyway.
Previously unnannounced additions include the addition of Chiseled Stone Brick and Mob Heads (Skeleton, Wither Skeleton, Zombie, Human and Creeper) in Creative Mode, new behaviors such as Snow Golems melting and dying in the Nether, and fixes to game lighting, memory, and smalls issues like seams in clouds. You can look at a full list of changes below.
Please note that 4J just sent the update to Microsoft two days ago and it is still awaiting approval.
