The United States Code is updated on a six-year revision cycle. The main volumes are released as a comprehensive revised edition roughly every six years, reflecting reorganizations and consolidations of statutes. In between these major revisions, changes enacted by Congress are kept current through annual cumulative supplements. So the six-year schedule is the best description of when the main volumes are published, making annual updates part of the ongoing maintenance rather than a full new edition. The other options—annual, every ten years, or never revised—don’t fit how the Code is actually maintained.
