Hello, could you split out the migration from the fix for #105 ? 🙏
I would like to have some analysis done on the consquences as this is a breaking change layered on top of the breaking change from OTP

@Shakadak Reverting the changes made to the test files?

[Shakadak]

Yes, you can open a new pull request with the changes to the test files, though I may not have much time to deal with it this week. I'll ask around if someone else could handle it.

thanks :)
