Iris will need an update to work with Sodium 0.8.12 on 1.21.1.

I need it too! Please!

Would be great to have, since the newest sodium is required to use Veil on some AMD GPU driver versions.

Now since Sodium 0.8 for 1.21.1 is released, other mods start requiring Sodium 0.8 too (e.g. Supplementaries, Aeronautics, Sable)
