New pages is a special page that lists recently created pages in reverse order of creation, with creation date and time, current size, user who created the page, and first edit summary. It also provides links to patrol these new pages when that feature is enabled.
The ability to filter by user was added as part of Phabricator task T8448.
Please note that transclusion of special pages, including Special:NewPages, is disabled on Gamepedia due to technical issues. Specifically, the issue was that any user visiting a page on which a special page is transcluded would be logged out.
