Highlights

1.21.10 alpha

Now supports 1.21.10 alpha. Not recommended for production use as its still in an alpha state.

Support for 1.21.7 and 1.21.8 has been dropped in favor of 1.21.10. In the future, I will likely only actively support LTS releases (1.20.1, 1.21.1) and the latest hotfix (1.21.10 currently). If you still need 1.21.4/1.21.5, let me know.

missing on 1.21.4: ebe, leaf culling, and cit resewn

missing on 1.21.5: previous missing, modernfix

missing on 1.21.10 alpha: 1.21.5 missing mods, continuity, ears, fastquit, language reload, polytone, worldhost, animatica. along with noisium and threadtweak from adrenaline
