https://github.com/HansKristian-Work/vkd3d-proton/releases/tag/v2.8 I wanted to make a pull request but saw that you're using a separate clone of their repo to distribute this component. Wouldn't it be better to add ZSTD support to Bottles via one of the 3 Python libraries mentioned by Facebook? See below: http://facebook.github.io/zstd/ Then we could point directly at the official repo to simplify maintenance of Bottles.
