The latest version (post Wave Cyclone Update) But now in 1.18.2!!!

Projectiles are more "Primitive" as making projectile models work in this version causes issues, so projectiles use the default models, but the items should work relatively the same as the 1.20.1 versions.

Updates to this version may be slower, as everything would need to be copied over, but besides that, this version gives more freedom to those who play older versions of minecraft java.
