Fixed in the new version

Same here:

Also it has the sodium 0.5 listed as a dependency on modrinth
https://modrinth.com/mod/chunks-fade-in/version/v1.0.1-1.20

I'm working on compatibility with Sodium 0.5.x and I hope that I'll finish it soon

Also it has the sodium 0.5 listed as a dependency on modrinth
https://modrinth.com/mod/chunks-fade-in/version/v1.0.1-1.20

This happens because I did not explicitly set a specific version of Sodium, so Modrinth automatically displays latest one
