Just dropping a quick change request to avoid this being merged by accident. We'll want to undo the changes to the download URLs.

[mwbrooks]

I don't think we want to change this URL because our download URL is not changing.

[lukegalbraithrussell]

ah yes my bad i thought i undid all these

[mwbrooks]

👍🏻 Everything else is looking good! We'll just want to undo that one line and then we can merge away!

✅ Thanks a bunch for the updates! Looks good to me.
