This is about the naming of releases in Azure DevOps (formerly known as TFS and VSTS). The default pattern of release names has been, as long as I can remember, sequential within the definition's scope: "Release 1", "Release 2", etc. That's been a minor pet peeve of mine for a while, and now we've come up with a technique to change this format to something more informative. Specifically, one can name releases with respect to the current product version, as every reasonable project team would want to.
