It has been at least three months since we've breached changset 2 million. That changeset had to do with making some corrections in a train depot in Brussels. The user, who "owned" the changeset, is now (mostly) making corrections for data consistency's sake.
My last changeset ID is 2955015. Good luck to the future owner of changeset 3000000, and to the persons who will break even more milestones for OpenStreetMap!
