The Winter 2016 FreeBSD Bugzilla Cleanup is a recommended process of cleaning up open (Status != Closed) issues in an automated or semi-automated way conforming to the following criteria:
1. Update requests, with or without attached patches, for ports that have meanwhile updated. Recommended action: Close → FIXED with a quote of revision where it was fixed.
2. Build failure reports, for ports that Portsmon shows are buildable since. Recommended action: Close → Unable to reproduce
3. Issues about ports that have been deleted from the tree. Recommended action: Close → Overcome by Events
