1.2 version minecraft | Iron golem |
1.2.1 was a major update to Minecraft (Java Edition) released on March 1, 2012,[1] which adds a new height limit of 256 blocks (changed from 128) as a result of the new Anvil file format, zombie sieges, and generated features including jungle biomes, wooden bridges in mineshafts, and desert wells. It also added new blocks and items – bottles o' enchanting, redstone lamps, fire charges and chiseled stone bricks – and two new mobs, iron golems and ocelots.
