The first 1.18 pre-release is here!

From now on, you should mostly see bugs being fixed. In addition to that, pre-releases don't follow the regular snapshot cadence of releasing on Wednesdays, so keep an eye out!

That being said, this pre-release introduces biome blending, which means that you should no longer find harsh borders between new and old terrain. On top of that, we've also reintroduced the Amplified and Large Biome world types.

Happy mining!

CHANGES IN 1.18 PRE-RELEASE 1

Amplified and Large biome worlds have been adapted to the new terrain and are now once again available in the Create World screen
Removed world types “Caves” and “Floating islands” from the world creation screen
The transition between new and old terrain is less “cliffy”
- Will surface height blend? Yes
- Will biomes blend? Yes
- Will caves blend? Your mileage may vary

TECHNICAL CHANGES IN 1.18 PRE-RELEASE 1

--report option in data generator now creates full worldgen reference files instead of just biomes
