Trivia

  • 1.17 is the first update since 1.3 to have no official name referring to the entire update. However, part of the update is placed under the name "Nether Update Part II", and it is not uncommon for people to use it to refer to the entire update.
  • This is the first update to keep version-specific menu panoramas from previous versions since they were introduced in 1.13.
  • In Java Edition, Cave Update features are planned to be released gradually, between versions 1.17 and 2.2. However, in Bedrock Editions, all Cave Update features are released between 1.17.x and 2.0.x, in versions 1.18.x, making most Cave Update features, except those introduced in 1.17, Bedrock Edition exclusives when they were first introduced.
  • After 1.17, there is a brief moment where version numbers are not the same between Java and Bedrock editions, when the Cave Update features are released on Bedrock Edition in 1.18.0. Soon after, the phase number was incremented to 2 on both platforms, the first time it has been incremented since they were re-introduced in Alpha in July 2010 on Java Edition, or since version 1.0.0 in December 2016 on Bedrock Edition.
