After updating to 1.11, all recipes from Compressed no longer work.

I noticed Compressed was updated to 2.0 in 1.11, which requires Fabric Loader 0.15.3 or greater. Downgrading to Compressed 1.80, which is the version used in 1.10.1, resolves this issue.

Just stumbled upon it too - apparently there are two 2.0.0 uploads for Compressed, and the one from December doesn't have the recipes bundled.
The February upload is a good one.
