Trivia[edit]

  • 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.
  • One of the new advancements, "Ol' Betsy", is possibly a reference to Disney's Robin Hood.[2]
