In this week I stumbled again into very common Azure Devops guestion.
Where I can see the changelog?
Build based changelog is available at pipelines page, but Azure Devops has also deployment changelog, which is indeed quite well hidden under releases tab.
First open latest deployment from “Releases” tab, then click the “Stage 1” or what ever your stage name is under the Stages box (yes, it is a link even though it doesn’t look like it!). Now on commits tab you can review changes compared to previous release and even change the compared release with change button.
Azure DevOps has also few very good extensions for changelog / release notes. Check them out also if this out of the box solution is not enough.
