The latest Minecraft developments have largely targeted on the ‘caves’ aspect of the Caves and Cliffs replace, but now we’re finally getting some more cliff motion - or quite, a big revamp to how mountains get generated, with the addition of 5 new sub biomes to spice up your tall, rocky terrain.
The most recent Bedrock Version beta introduces five new mountain sub biomes, called lofty peaks, snow capped peaks, snowy slopes, mountain grove, and mountain meadow. These will work alongside the prevailing mountain sorts to create a more diverse selection of alpine locations to discover. The new peaks look spectacular in the official picture above, but scroll down a bit to see a fan-made comparison of new and old mountains. It’s a large change.
While this is a Bedrock beta, these changes should come to Java as properly - as the Java snapshots have given us early appears at options like deepslate, glow squids, and the brand new ore textures, it looks like Bedrock beta gamers are getting their own early looks at some new features, too. https://minecraft-server.live/ (This update, by the way, also adds glow squids and the ore textures to the Bedrock beta.)
You may get full patch notes on Reddit, and a greater take a look at the new mountains on the official site.
