Lithium 0.12.3 for Minecraft 1.20.6

Lithium 0.12.3 is the first release for 1.20.6.
The new minimal_nonvanilla package is introduced, which is meant for optimizations which technically are different from vanilla in an observable way, but do not affect any gameplay or any contraptions. If any negative effect on your contraptions or gameplay is noticeable, please report this to our issue tracker, as this would be considered to be a bug. Check https://github.com/CaffeineMC/lithium-fabric/blob/mc1.20.6-0.12.3/lithium-mixin-config.md for a detailed description of what each package does, and how to disable certain optimizations if needed.
