What you need to know

  • Mojang Studios is preparing to release 1.18 'Caves and Cliffs Update' Part Two before the end of the year.
  • Laying the groundwork for the upcoming content update is Minecraft: Bedrock Edition patch update 1.17.40.
  • The update is rolling out to all players everywhere with a wealth of bug fixes, improvements, and optimizations.

As the Minecraft community recovers from all the news and announcements during Minecraft Live 2021, Mojang Studios is releasing Minecraft: Bedrock Edition 1.17.40, a patch update that includes a ton of bug fixes and general changes across every platform Minecraft is available. The update is now rolling out to everyone, and continues to polish and stabilize Minecraft ahead of a new content update arriving later this year.

1.18 Caves and Cliffs Update Part Two is slated to release before the end of the year, and will bring massive alterations to world generation and plenty of brand-new features to Minecraft when it does. The 1.17.40 is building the foundation upon which the 1.18 content update will release on, and as such focuses primarily on bug fixes and polish for one of the best Xbox games around.

Even before we have the second half of the Caves and Cliffs Update in our hands, Mojang has already announced what's coming next. The Wild Update is arriving at some point in 2022 with its own batch of features, but we'll have to wait a while yet before we see any sign of that release, and the new Minecraft toys and gifts that will inevitably arrive with it.

In the meantime, Minecraft: Bedrock Edition patch update 1.17.40 is now available, so be sure to download and install it as soon as possible for the best Minecraft experience. In case you missed it, Minecraft is also heading to Xbox Game Pass for PC as part of a new bundle, making it even easier to play the game wherever you want.
