CC wolfeallison rhn-support-nemiller

Background 

Due to recent change, automatic upgrade for cluster version are now only doing latest z-stream only.

We like to change that, and allow customers who wish doing so, be able to automatically upgrade y-stream as well.

The new API will contain a boolean if y-stream upgrades are enabled (default: false). If the customer wants to opt-in on automatic y-stream upgrades they should have an option in the UI to enable it.

Deliverables

Marvel mockups for new y-stream option (WIP) https://marvelapp.com/prototype/hj71d5h/screen/85644006
