-- Managed Dependency Upgrade
-You DO NOT need to raise an issue for a managed dependency version upgrade as there's a semi-automatic process for checking managed dependencies for new versions before a release. BUT pull requests for upgrades that are more involved than just a version property change are still most welcome.

 An issue will be closed as a duplicate of the immediate pull request, so you don't have to raise an issue if you plan to create a pull request immediately.
