Snapshots and subsequent updates

There were 42 snapshots and ten pre-releases for 1.13.

1.13.1

Released on August 22, 2018, this is a minor update that added dead corals, a world list search bar, the /forceload command, made some changes to fish mobs, coral, squids, tropical fish buckets, and fixed 149 bugs.

1.13.2

Released on October 22, 2018, this update included a few performance improvements and upgrade issue fixes left over from 1.13.1.

Trivia

• Originally, this update was intended to be released as two separate updates: 1.13 "Technically Updated" would have made the technical changes and 1.14 "Update Aquatic" would have added the ocean features, but Mojang later decided to merge the two updates into one.
• Snapshot 18w03a was released on January 17, 2018. However, the snapshot contained some broken commands, so just one hour later, 18w03b was released. This was the shortest time ever between two updates.
• This is one of the few updates where Bedrock Edition gets these features first.
• The first planned release day was May 30, 2018. However, due to crucial bug fixes needing to happen, its full release had been pushed back.
• It is currently the update with the most pre-releases, at 10 prior to its official release.
