+NOTE: In GitLab 11.7, we introduced the full fledged [Releases](index.md)
+feature. You can still create release notes on this page, but the new method is preferred.

+You can add release notes to any Git tag using the notes feature. Release notes
+behave like any other markdown form in GitLab so you can write text and
