+* Sections in the parser test framework have been renamed and the old
+ section names are deprecated. Please use "!!wikitext" and "!!html"
+ (or "!!html/php") instead of "!!input" and "!!result". This allows
+ us to extend parser tests to accommodate additional input/output
+ pairs, such as "!!html/parsoid" (for the output of the Parsoid
+ parser, where it differs from the PHP parser).
