Hi 👋 @lparrott! Release Engineering asks that teams use the following process for routine reviews:

1. After creating a non-draft pull request that includes automation updates, a release engineer will be auto-assigned to the PR.
2. When dev review is complete and the PR is ready for the release engineer to review, add a "ready for RE review" label to the PR to let us know when the PR is ready for us to review.
3. If you've added the "ready for RE review" label but haven't received a review within a 36 hours, @-mention the assigned RE in a comment on the PR.
4. If you don't receive a response from the assigned RE by the end of the next business day (or your request is urgent), post a message to #sfdo-releng-support that includes a link to this PR and one of us will review as soon as we're able.

@lparrott Thank you for making this update so quickly! I added a suggestion with the CX-approved text that I just got back from the reviewer.

±: Since the option was just added we need to update the minimum_cumulusci_version to 3.74.0.

This will break your builds until we get MetaCI updated, however.
