If you write, maintain or are otherwise active in development, and directly or indirectly make use of MediaWiki, then you should subscribe to:
mediawiki-api-announce@lists.wikimedia.org
That is a mailing list that only brings important announcements for developers that use MediaWiki as an API.
Note that this list is not limited to API as "api.php" but about MediaWiki as a application programming interface (API) in general.

If you're asking people to sign up for a mailing list, it's generally nice to link them to a form where they can do so. ;-)
