## [Unreleased]
### Changed
- [Tweaked ore generation to better fit Minetest's new defaults.](https://github.com/minetest-mods/moreores/pull/45)
- Three layers (two underground and one high air/space) are now used instead of just one layer.
- Chunk size is no longer used as clust size anymore. Clust sizes are usually
just 3 nodes and not the whole area ("chunk"), where the ores are generated.
- Adjusted several default values.
- Mithril is now generated *below* diamond. Note that there was a change
in Minetest 5.0.0 where most ore generation was shifted to much lower
altitude (shifting diamond generation altitude below mithril generation altitude).
- The mithril ores are now also grouped together and not just found as a
single node in one chunk.
- The same overall ore density is retained in the deep layer.
