Register history
Each change to the register, or to the rules behind it, is recorded here with its date, newest first. Past lines are never rewritten.
A data line means entries were added or revised; a correction came from a reader through the form; wording and method lines concern the text of the site and the way its entries are compiled.
| Date | Change | |
