A few weeks ago I was wondering if I should migrate my PRs from Well, that's my bad, I should have done it to avoid you the trouble of opening this PR. But thank you for this change ❤️ On that topic, feel free to reach out if you need help with the zstd stuff in the future. You will probably not need it, but we never know! |
Nice! Thanks! ❤️
I think opening myself gave me context on why this is a good idea, so we are good. 😄 |
