Trailer

Template:Main Similar to Minecraft:Java Edition 1.1, an official video documenting some of the 1.2's major features was released on Mojang's official Minecraft:YouTube channel on March 1, 2012. The video was made by Minecraft:Hat Films, who have made update trailers and videos for Mojang in the past.

Trivia

• Development versions for 1.2 started only a week after 1.1 was released.
• Despite the number, 1.2.1 is the first full release, not a minor update.
