GitLab 14.0 removes support for the release description in the Tags API. You can no longer add a release description when [creating a new tag](https://docs.gitlab.com/ee/api/tags.html#create-a-new-tag). You also can no longer [create](https://docs.gitlab.com/ee/api/tags.html#create-a-new-release) or [update](https://docs.gitlab.com/ee/api/tags.html#update-a-release) a release through the Tags API. Please migrate to use the [Releases API](https://docs.gitlab.com/ee/api/releases/#create-a-release) instead.
