How notices are selected

A change counts when an official listing gives a shutdown, retirement or deprecation date, or a lifecycle past active. It also counts when its title or text names a deprecation, retirement, sunset, shutdown, end of life or discontinuation that is not negated. Dates are the ones the listing or text names.
