ℹ️ Information

ℹ️ Version support matrix reminder

Full: The main versions we care about, typically where the team spends their effort. It's recommended that people target these versions and not intermediate versions. Can think of this as the LTS system.

Legacy: Less attention, but still supported. Not the main focus, but if doing "global" changes, should be included.

Minimal: Rarely used versions, often versions that quickly got replaced by hot-fixes from Mojang. The goal is to have the build system work for these versions. However there is no real effort from the team for back porting any fixes to these versions.
