Release Manager (Wikimedia)

The WMF Release Manager is the person who is in charge of all releases (or deployments) to the WMF servers (commonly referred to as the "WMF Cluster"). This person is the point of contact and owner of the Deployments Calendar where the schedule of deployments is maintained. This schedule includes everything from new WMF-internal releases of the MediaWiki software (currently every two weeks, see eg MediaWiki_1.22/Roadmap) to major changes to the production servers. This role is currently filled by User:Greg_(WMF). Please contact him with any questions you might have concerning these topics.

This role differs from the MediaWiki Release Manger in that the MediaWiki Release Manager focuses solely on the release of the MediaWiki software for non-WMF users, specifically the official numbered releases that can be found on the en:MediaWiki version history page.
