Task 12 is a single use task that removes and replaces certain deprecated parameters in existing {{London Gazette}} templates. The original {{London Gazette}} has been converted to be a wrapper template around {{cite news}} and later around {{cite magazine}}. To make the template both stylistically and functionally similar to common cs1|2 templates, some of the original parameters have been supplemented with their equivalent cs1|2 parameters. Task 12 revises existing instances of the templates to use the new parameters.
