Caves & Cliffs split up into two updates
Mojang has announced that they'll need a bit more time to deliver the upcoming Caves & Cliffs update for Minecraft, so they'll split it up and release it in two parts instead.
The first half of the update will be released this summer, while the second part will come closer to the holiday season. Releasing the full package this summer would mean “compromising on quality,” and Mojang wouldn't take the chance of running into game-breaking bugs.
The new world: “There are also significant technical challenges we need to overcome before certain parts of the update are ready to ship,” Mojang explained. World generation is being overhauled, so once Cliffs & Caves is out newly generated worlds will look quite different from old ones.
Slowed down: The studio is also concerned about performance, since “more stuff in the game also slows it down and we want to avoid that.” There is also COVID-19 restrictions in play, and the team has been progressing a bit more slowly since it started working from home.
