Right now the aha release phases just seem like an informational overlay with no connection to the features themselves or their JIRA equivalents. So when work gets estimated in jira or progresses these timelines don't change. I have to keep them in sync manually.
If I could associate a aha release phase with a sprint and have the duration and time frames stay in sync that'd be a great start
As to when I need it ... without it, I'm just going to use milestones only and that's not nearly as useful
Releases contain release phases and milestones to help you manage customer launches -- when specifically looking at release phases, they typically contain both technical and non-technical work.
Features can also be placed into release phases, to help with better understand the different aspects of the launch.
We would suggest adding a custom field at the feature level to track sprints. It would require manually updating the field, but would allow for reporting by sprint. At this time, we do not have plans to make updates in this specific area due to community feedback and current priorities. We hope you can understand.
