With an epic you can enter a start and end date, or have it be automatically calculated. The problem/idea is that this automatic calculation of start and end date should be based on the release dates for the releases in which the epics reside.
Epics can now automatically inherit their start and end dates from the release they belong to. This ensures epic timelines stay aligned with release schedules and removes the need to manually manage dates when epics are planned within a release.
Teams doing Quarterly releases move epics around and want them slated under what release they all under. They would also help if there was logic to also adjust the features under both the release and the epic.
This makes the translation of reprioritized Epics to the Engineering plans much more seamless.
