Trivia

The first snapshot of Java Edition 1.13, 17w43a, was released in the same week of the year as 18w43a.
In the minecraft.net blog post introducing 18w43a, Adrian Östergård captioned the section describing loom using the phrase "Bröther, may I have some lööm?". This is a reference to the cat wanting fruit loops internet meme.
18w43a holds the record as having the most content in one developmental release, adding nearly 3 times as much content as the entirety of Java Edition 1.4.2 did in October 2012.
- The previous record for most content added in one developmental release was held by 15w31a for Java Edition 1.9.
As with 18w43b, 18w43a was released exactly 6 years after the Minecraft issue tracker.
