This seems really bizarre to not be included with the .0 release. The features are live, but the label states "Your instance (current version) is 13.9". It could do with some more refining perhaps.
Hi Operyl, GitLab PM here. Thanks for the feedback on What's New. As you point out, it looks like we have some opportunity for refinement and better/clearer messaging for folks that update right away to the .0 release. I've opened up this issue to track that work and welcome your feedback or ideas there. Thank you! https://gitlab.com/gitlab-org/gitlab/-/issues/325591
