review "build definition"
Within VSTS, ensure changes to build and release definitions go through a similar review process to code. Essentially, I'd want to protect our build and release definitions in the same way we protect our master branch - only reviewed & approved changes make the cut.
- Make your changes and save as a draft.
- Test the build / release using that draft
- When wanting to publish this draft, it needs 'n' reviews to approve it
