Minecraft's Caves & Cliffs update has been split into two parts, with the first still set to arrive this summer. Mojang explained the move, saying that the ambition of the update has made it difficult to stick to the original timeline. The second part of the Caves & Cliffs update will now release this holiday season.

"We know this news is disappointing to many of you, but there are several reasons for this change," Mojang said in a statement. "Firstly, we strive to deliver the most polished experience possible, and including all the Caves & Cliffs features in the summer update would have meant compromising on quality. And even though occasional bugs are a reality of game development, we want this update to be an amazing experience, not wreak havoc on your meticulously crafted worlds."

In particular, Mojang said, the update is slated to introduce a complete overhaul to the overworld generation, which also naturally impacts caves and mountains. "Not only do we have to consider every effect this can have on the world but also how it will affect performance. Basically, having more stuff in the game also slows it down and we want to avoid that."
