Version lifecycle
MediaWiki operates on a "continuous integration" development model, where software changes are pushed live to Wikimedia web sites such as Wikipedia on a regular basis.
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.
The release manager strongly recommends that wiki operators subscribe to the 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.

Versions not included in this table are to be considered obsolete and will not receive security fixes. The release manager has also issued a strong recommendation that versions not listed above as current version or legacy version should not be used in a productive environment. They may contain critical security vulnerabilities and other major bugs, including the threat of possible data loss and/or corruption.
