## Upgrading
*If you have any Incompatible Changes in the above Changelog, outline how users of prior versions can upgrade once this PR lands or when reviewers are testing locally. A common upgrading step is "Database reset and re-index required".*
## Checklist for your PR
<!--
Ideally a PR has all of the checkmarks set.
If something in this list is irrelevant to your PR, you should still set this
checkmark indicating that you are sure it is dealt with (be that by irrelevance).
If you don't set a checkmark (e. g. don't add a test for new functionality),
you must be able to justify that.
-->
- [ ] I added an entry to `CHANGELOG.md` with this PR
- [ ] If I added new functionality, I added tests covering it.
- [ ] If I fixed a bug, I added a regression test to prevent the bug from silently reappearing again.
- [ ] I checked whether I should update the docs and did so if necessary
