 ## v1.14: The untitled update (unreleased)
  - Add `//dome+`, which allows you to change the direction the dome is pointing in, and also create multiple domes at once
+ - Add `//metaball`, which renders 2 or more [metaballs](https://en.wikipedia.org/wiki/Metaballs) in Minetest
  - Migrate from `depends.txt` to `mod.conf`

 # worldeditadditions_core
 
 This mod's purpose is to provide a solid base upon which the rest of WorldEditAdditions can function. Once it is complete, we will be able to mark our dependency on `worldedit` itself optional. To get to that point though will still require a significant effort in implementing enhanced versions of all existing WorldEdit commands. If you've got some free time and a great idea for a command, please do open a pull request! :D
+
+In short, `worldeditadditions_core` is a reimplementation of a number of underlying parts of the worldedit engine. Parts of `worldeditadditions_core` are likely to look very similar to parts of WorldEdit - this is because inspiration was taken from Uberi/WorldEdit when implementing `worldeditadditions_core`.
