development model, where software changes are pushed live to Wikimedia websites such as Wikipedia regularly. </p><p>In theory, new major releases are issued every half-year, and release branches continue to receive security updates for up to a year after the first release. However, 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 that have reached their end-of-life status. </p><p>The release manager strongly recommends that wiki operators subscribe to the <code><a href="https://lists.wikimedia.org/postorius/lists/mediawiki-announce.lists.wikimedia.org/" class="extiw" title="mail:mediawiki-announce">mediawiki-announce</a></code> mailing list, which receives notification of all releases, and ensure that their wiki runs the most up to date version of the software possible.

Managing the maintenance bug fixing of extensions and choosing the right version of an extension in cases where the HEAD development version relies on features not yet available in stable or oldstable MediaWiki core can be challenging. </p><p>Extension maintainers are therefore strongly encouraged to maintain a git branch for each extension version corresponding to a MediaWiki version. (See <a href="/wiki/Special:MyLanguage/Compatibility#MediaWiki_extensions" title="Special:MyLanguage/Compatibility">Compatibility#MediaWiki extensions</a><span style="display:none"><a href="/wiki/Compatibility#MediaWiki_extensions" title="Compatibility"> </a></span> for details.) For extensions hosted in Wikimedia's git repos, such branches (with names such as <code>REL1_30</code> for MediaWiki 1.30) are created automatically from master when a new MediaWiki version is branched (on the assumption that the extension master is compatible with MediaWiki master at all times). However, it's preferable for the extension maintainer to fix bugs not only in HEAD but also in the oldstable and stable versions (by backporting the fix to the old branches if necessary). </p><p>The goal of these rules is that people or organisations installing MediaWiki can rely on installing the newest release of a version and matching extensions by a simple method, e.g., for 1.20.x core by referring to <code>REL1_20</code> in git. It avoids tarballs and zip files with non-relevant and unpredictable names. </p> <div class="mw-heading mw-heading2 ext-discussiontools-init-section"><h2 id="See_also" data-mw-thread-id="h-See_also"><span data-mw-comment-start="" id="h-See_also"></span>See also<span data-mw-comment-end="h-See_also"></span></h2></div> <ul><li><a href="/wiki/Special:MyLanguage/Compatibility" title="Special:MyLanguage/Compatibility">Compatibility information for MediaWiki, most importantly PHP and MySQL</a><span style="display:none"><a href="/wiki/Compatibility" title="Compatibility"> </a></span></li> <li><a href="/wiki/Special:MyLanguage/Stable_interface_policy" title="Special:MyLanguage/Stable interface policy">Stable interface policy</a><span style="display:none"><a href="/wiki/Stable_interface_policy" title="Stable interface policy"> </a></span></li> <li><a href="//wikiapiary.com/wiki/Generator:Generators" class="extiw" title="wikiapiary:Generator:Generators">Generators on WikiApiary</a> - Statistics about the use of different versions of MediaWiki.</li></ul>    </div><noscript><img src="https://login.wikimedia.org/wiki/Special:CentralAutoLogin/start?type=1x1" alt="" width="1" height="1" style="border: none; position: absolute;"></noscript> <div class="printfooter" data-nosnippet="">Retrieved from "<a dir="ltr" href="https://www.mediawiki.org/w/index.php?title=Version_lifecycle&oldid=6822851">https://www.mediawiki.org/w/index.php?title=Version_lifecycle&oldid=6822851</a>"</div></div> <div id="catlinks" class="catlinks" data-mw="interface"><div id="mw-normal-catlinks" class="mw-normal-catlinks"><a href="/wiki/Special:Categories" title="Special:Categories">Categories</a>: <ul><li><a href="/wiki/Category:MediaWiki_development" title="Category:MediaWiki development">MediaWiki development</a></li><li><a href="/wiki/Category:MediaWiki_Releases" title="Category:MediaWiki Releases">MediaWiki Releases</a></li></ul></div><div id="mw-hidden-catlinks" class="mw-hidden-catlinks mw-hidden-cats-hidden">Hidden category: <ul><li><a href="/wiki/Category:Pages_using_the_EasyTimeline_extension" title="Category:Pages using the EasyTimeline extension">Pages using the EasyTimeline extension</a></li></ul></div></div> </div> </main> </div> <div class="mw-footer-container"> <footer id="footer" class="mw-footer" > <ul id="footer-info"> <li id="footer-info-lastmod"> This page was last edited on 1 November 2024, at 21:51.</li> <li id="footer-info-copyright">Text is available under the <a rel="nofollow" class="external text" href="https://creativecommons.org/licenses/by-sa/4.0/deed.en">Creative Commons Attribution-ShareAlike License</a>; additional terms may apply.
