== Trivia ==
* 1.17 is the first update since 1.3 to have no official name. However, it has been widely nicknamed by the community as "Nether Update Part II".
* This is the first update to keep version-specific menu panoramas from previous versions since they were introduced in 1.13.
*Java Edition 1.17 has several unused features intended for the Cave Update. Mojang has stated that these features were added early because they "just had some free time to make them right now, and [they] can't be sure about how much time [they] will have [for 1.18], so [they] decided to make them early to save some time later."
**These features may also exist in Bedrock Edition 1.17.0 but are unobtainable there without third-party software, but this claim has not been confirmed.
