We have two environments and auto-deploy to staging in a lot of our projects. We have a release per CI build, CI builds correspond to a PR merge so usually a deployable feature.

Current flow: Some feature or features are approved for release, I go to the overview screen and memorise which version is deployed in production, then I go to the releases screen, scroll down the last release deployed to production, scroll up checking the release notes to see if there is anything that can't go out to production.

In a lot of cases we have 4-5 new releases between staging and production (more if our translations team have been working on a project). We also sometimes have batches of features approved through our QA process so it's a case of doing this flow repeatedly for several projects at once.

It would be really helpful to either see all of the release notes that are between the current production deployment and a given release, or even just an <HR> or something between entries on the Releases page that says "Environment X is here".
