Minecraft has split off and delayed parts of its big Caves & Cliffs update

Minecraft’s big Caves & Cliffs Update has been split in two, with the latter part now not due until “around the holiday season”, developer Mojang said today.

While some of the update will still arrive this summer – more on that below – this constitutes a delay for many of its more ambitious parts.

Explaining the cause in a detailed blog post and FAQ, Mojang said that “significant technical challenges” had stemmed from the far-ranging nature of this update, which touches on fundamental parts of Minecraft’s world-generation system.

“With this feature, we are completely reshaping the Overworld, including the build height,” Mojang wrote. “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.”
