1.4.6[1] is an update to Minecraft (Java Edition) that was released on December 20, 2012.[2] It introduced fireworks, enchanted books and the Thorns enchantment. It also added a warning for users playing on soon-to-be unsupported systems (PowerPC and Java 5). While it was not the last update to 1.4, it was the last one before the snapshots of 1.5 started.

A pre-release version of 1.4.6 was released on December 17, 2012;[3] this pre-release version was later re-uploaded to fix an issue with mobs spinning.[4][5] The release version of 1.4.6 differs from the reuploaded pre-release by fixing a crash issue.[6]
