Trivia

 * The first snapshot of 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, having nearly 3 times as much content as 1.4.2 had in October 2012.
 * The previous record was held by 15w31a for 1.9.
