In addition to mapping custom fields between Productboard and Jira, you can now map Jira story points to Productboard effort.

You can now push features as well as subfeatures into Jira. Features most often map to epics but can also map to stories, bugs, subtasks, and other issue types. Subfeatures often map to stories but can also map to bugs, subtasks, other issue types.

Optionally, link Productboard features to existing Jira issues.
