+- In the case of a minor or patch version, move the major version tag to the latest version. This can be done by manually running the "Update major version tag" workflow.
 - Update `CHANGELOG.md` with a new section with the release name and date directly below the `## Unreleased` header, e.g., `## v2.7.1 - 2024-12-21` .
     - If you made updates to the release notes in the GitHub release, add them to `CHANGELOG.md`.
 - If there are additional commits on the release branch, merge the release branch back into `main`.
