The GMDN Agency is introducing GMDN Category Versioning on 1st April 2026, as part of an update to our data model.

This change will improve stability, allowing GMDN Categories to evolve in a controlled way with stakeholder feedback.

For any questions, please contact the GMDN Agency at communications@gmdnagency.org.
