In theory, new major releases are issued on a quarterly basis, and release branches continue to receive security updates for up to a year as of first release. Due to time constraints and rapid refactoring of the code base, we cannot support obsolete releases forever, and security and critical updates are not applied to releases which have reached their end of life status. The legacy (''previous'') version is supported up to six months after release of the current (''latest'') version.

In theory, new major releases are issued on a half-year basis, and release branches continue to receive security updates for up to a year as of first release. Due to time constraints and rapid refactoring of the code base, we cannot support obsolete releases forever, and security and critical updates are not applied to releases which have reached their end of life status.
The release manager strongly recommends that wiki operators subscribe to the [[mail:mediawiki-announce|mediawiki-announce mailing list]], which receives notification of all releases, and ensure that their wiki runs the most up to date version of the software possible. These announcements are also posted to mediawiki-l and wikitech-l.
