Summary for Tech News readers
- importScriptURI( url ) and importStylesheetURI( url ) functions are deprecated. They have been superseded by ResourceLoader. You should replace their usages with mw.loader.load( url ). The old functions will be removed in the future.
- importScript( wikiPage ) and importStylesheet( wikiPage ) functions are not deprecated yet. They will be deprecated when a suitable ResourceLoader-based replacement is created. For new scripts, it is recommended to use the Gadgets system instead.
Original bug summary:
If they are in fact deprecated, users should see a warning in the console so that they can start migrating their code to mw.loader.load before these functions are finally removed from MW core.
