@floehopper so we've tested the alpha release in one of our biggest repos, and it seems to be working + the warnings can be captured by https://github.com/Shopify/deprecation_toolkit, so I think we're good 👍 (Thanks @byroot for the help). We'll wait for the stable release before integrating it though 😄.

@wasabigeek @byroot Brilliant - thanks so much for doing that and for letting me know. I'll try to get the stable version released early next week.

@wasabigeek I'm afraid there's going to be a bit of a delay on the release due to a family emergency. Hopefully later this week. 🤞
