Hi 👋!

Thank you 🙏 for improving the workflows here! I agree this is a good change, so I tried to rebase it and add a CHANGES entry, but I don’t think you ticked the “allow updates from the maintainers” checkbox on the PR so I can’t do so here.

Could you please rebase one more time and add a CHANGES/694.misc.rst file please?

[mjpieters]

Never mind, the permissions issue was entirely down to my own gh command line token needing an update.

This will be merged as soon as the checks complete!

Thanks for merging 👍
