JBoss.org has been fairly regularly upgrading the JIRA instance, and a recent upgrade has incorporated a small improvement to how JIRA integrates with GitHub. We've had for some time a GitHub-based workflow in JIRA, so that you can use "Workflow -> Link Pull-Request" and "Workflow -> Pull Request Closed" and similar actions to point JIRA to the appropriate GitHub pull-request. But now each of ModeShape's issues have a new "Commits" tab that shows a summary of all commits merged on the affiliated pull-request(s). Links within the Commits tab will take you to our GitHub repository.
This is a small change and improvement, especially when looking at older issues and wanting to know what changed.
