Changes to Sitefinity are released as NuGet packages that you can decide whether or not to apply. The infrastructure provided by Sitefinity Cloud can be used to test, verify, accept, or reject the changes. This includes the staging environment, combined with the control provided by the deployment pipeline. Progress cannot offer the ability to test, verify, and accept or reject changes to Sitefinity Cloud services that are directly provided by Microsoft, such as Azure DevOps.
