As a user of selecting a cluster version, I see a new "Channel Group" field, but I do not know what it is.   A tooltip after the field label would be helpful which explains "What is a channel group" and "Why would I want to change it?  ..."to benefit from a longer support cycle..."

Note: "Learn more..." link in tooltip will need to be dynamic based on if in OSD .vs Rosa wizard

A longer discussion on the tooltip content in this slack thread.

Please reach out to wolfeallison tech writer

Per Allison on tooltip text: "A channel group determines the versions and updates available for your cluster. For a longer support life cycle, change the channel group to an Extended Update Support (EUS) version.
