  • 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.[15]
  • This is one of the few updates where bedrock 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.[16]
