fr.wikipedia.org has hundreds of pages that contain lists of recent articles by portal.
(all these pages, plus some updated by other bots):

This is the main way new articles can be reviewed by users interested in a specific domain.

Each portal has a tracking category, so this is certainly something that MediaWiki could support in a generic way. Ideally, there would be a special page to list the last n members of a category that can be included into others (like Special:PrefixIndex).

Note: MediaWiki already tracks these timestamps and makes them available through the API, but this request is not as simple as providing a UI for this. Based on the feedback received for bots, two additional constraints are that:

• changing the defaultsort should not reset the timestamp ;
• a quickly reverted removal of the category should not reset the timestamp.
