- Revert the change that made all 1.21.x versions a single file, as it seems to be causing crashes
- Switch semver versioning system
Add support for 1.21.3 + make all the 1.21.x versions a single file (the CyanLib doesn't use things that changed between the different 1.21 versions, so separating each version is not needed)
Add support for 1.21.2
Make compatible with both 1.21 and 1.21.1
Backport to 1.20.1
