* [x] I have deployed and tested my changes
LetsEncrypt challenges passed
* [x] I have [updated relevant versions in `abra.sh`](https://docs.coopcloud.tech/maintainers/upgrade/#updating-versions-in-the-abrash)
No relevant versions to update
* [x] I have made my environment variable changes [backwards compatible](https://docs.coopcloud.tech/maintainers/upgrade/#backwards-compatible-environment-variable-changes)
Only new env vars were added
* [ ] I have added a [release note entry](https://docs.coopcloud.tech/maintainers/upgrade/#creating-new-release-notes)
Unsure if this is necessary but I'm happy to add notes if we want them 😄
