We use continuous build and deploys up through a test environment, and each changeset is tied to a work item (story). After the build is deployed to an environment, I think we can see every associated story for that build. Question is what has changed, functionally, both for verification/acceptance tests and for release notes, support training, and marketing. This is related to How can I identify which work items/user stories are in a selected build in Azure DevOps? except that we want to know before the candidate moves to a higher level environment and to collect the sum of unique changes since this pipeline last promoted to that environment
