From the release details, on the integrations, allow sending (and re-sending) all features in the release to GitHub.
Currently, one needs to manually send each individual feature to GitHub when starting a new release, which can take a really long time. The same if we make changes to the release.
Thank you for your idea. There are a couple ways this can be done today:
If releases are mapped to a Github record (e.g. milestones) you can send the release from Aha! to Github. This will automatically send/update all features in the release.
If releases are not mapped, you can use bulk edit on the Features > List. Here you can select multiple features and send them at once.
