## Checklist The [contributor guide](https://forgejo.org/docs/next/contributor/) contains information that will be helpful to first time contributors. There also are a few [conditions for merging Pull Requests in Forgejo repositories](https://codeberg.org/forgejo/governance/src/branch/main/PullRequestsAgreement.md). You are also welcome to join the [Forgejo development chatroom](https://matrix.to/#/#forgejo-development:matrix.org). ### Tests - I added test coverage for Go changes... - [x] in their respective `*_test.go` for unit tests. - [ ] in the `tests/integration` directory if it involves interactions with a live Forgejo server. ### Documentation - [ ] I created a pull request [to the documentation](https://codeberg.org/forgejo/docs) to explain to Forgejo users how to use this change. - [ ] I did not document these changes and I do not expect someone else to do it. ### Release notes - [ ] I do not want this change to show in the release notes. - [ ] I want the title to show in the release notes with a link to this pull request. - [ ] I want the content of the `release-notes/<pull request number>.md` to be be used for the release notes instead of the title.
