We have a couple of Release Pipelines (GUI) that are triggered on new Universal Packages. We have been using YAML for CI builds, and recently I discovered that Release stages can be defined in YAML as well.
The only issue I found is that I can't find a way to trigger this Release-YAML-pipeline on new arrival of a Universal Package in a Feed, like you can in the GUI Release pipelines.
The only option seems to be a Build Completion trigger?
