## Description of the problem, including code/CLI snippet It seems that the code we use to create a release from a tag [here](https://github.com/python-gitlab/python-gitlab/blob/8753add72061ea01c508a42d16a27388b1d92677/gitlab/v4/objects/tags.py#L19) has been deprecated and removed We should update to use the new release API I'll try to investigate a little later tonight as it is blocking my team for some automated release tools. ## Expected Behavior - set_release_description() create or update a release ## Actual Behavior - 404 error ## Specifications - python-gitlab version: 2.8 (and 2.5) - API version you are using (v3/v4): v4 - Gitlab server version (or gitlab.com): gitlab.com
