If you write, maintain or are otherwise active in development, and directly
or indirectly make use of MediaWiki, then you should subscribe to:
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

* Important changes in database schema (columns or tables added, removed or
changed in such a way that you should change your queries. Think for example
of the addition of rev_deleted, queries should most likely query for

* Major changes to the HTML layout (such as the change for the sidebar id to
* Hooks in MediaWiki PHP. Mostly for extension developers. Changes or
deprecation of hooks.

Also, whenever Wikimedia has scheduled a deployment of revision(s) or entire
branches that expose any change that was previously announced, a new mail

be prepared or tested in advance)
Hope to see you soon on mediawiki-api-announce(a)lists.wikimedia.org :)
