Version lifecycle/de

MediaWiki wendet bei der Softwareentwicklung das Modell der „kontinuierlichen Integration“ an, bei dem Softwareänderungen regelmäßig von den Websites von Wikimedia, wie bspw. die Wikipedia, übernommen und somit produktiv genutzt werden.

Theoretisch werden halbjährlich neue Hauptversionen veröffentlicht, wobei die Release-Zweige weiterhin bis zu einem Jahr nach der ersten Veröffentlichung weitere Sicherheitsaktualisierungen erhalten. Aus Zeitmangel und der schnellen Veränderung der Code-Basis können wir überholte Versionen nicht für immer pflegen, daher werden kritische Updates und Sicherheitsaktualisierungen nicht weiter gepflegt wenn sie das Ende ihres Lebenszyklus erreicht haben.

Der Veröffentlichungsmanager empfiehlt, dass Wikibetreiber die -Mailingliste abonnieren, die Mitteilung von allen Versionen erhält und sicherstellen, dass ihr Wiki möglichst mit der aktuellsten Version der Software läuft. Diese Ankündigungen werden auch zur  und   geschrieben.

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

Wichtige Daten für zukünftige Versionen
This table sets out the plan for future MediaWiki releases, including the date the branch will be made.

The branch dates may be incorrect, see for correct dates.

Release-Richtlinie

 * Point releases will be made at least monthly, on the last Wednesday of the month. Every point release will include updated i18n files as well as any bug fixes. No new features will be back-ported to point releases and support doesn't include extensions in general, see below (e.g. doesn't support current LTS).
 * A major release will be made every six months.
 * A long term support release (LTS) will be made every two years. There will be a one-year overlap in LTS support. For example, 1.19 was supported until May 2015. 1.23 was released the year before that so that people had it available as an LTS to move to and a year to make the transition.
 * Release notes will continue to be the basis for seeing what has changed. Because of the nature of a volunteer-driven project, it isn't possible to say with any certainty what will happen in the next 6-12 months.
 * To mitigate the problem of release notes, we will publish a list of new features in the upcoming LTS relative to the last LTS six months before it comes out. This means that about the time when 1.22 came out, an announcement was made for 1.19 users letting them know what changes they could expect in 1.23.

Verröffentlichungszeitplan
This timeline is a schedule for what needs to happen before the release of a new version. The date of the actual release is given here as REL (for “release”) and the suffix -# (for “number of weeks prior to release”).

Extension lifecycle management
Most MediaWiki installation include a significant number of extensions (WMF MediaWikis often around 80 extensions). 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, is a major challenge for all maintainers of MediaWiki installations.

Extension maintainers are therefore strongly encouraged to maintain a git tag or branch for their version corresponding to the release tag the stable and oldstable version. An initial version, that simply points to the state of the code at the time of the release may be created centrally. However, it is the responsibility of the extension maintainer to fix bugs not only in HEAD but also in the oldstable and stable versions. If the extension works with all of oldstable, stable and HEAD, this requires only to update the tags. However, if some changes are specific to later versions, the lifecycle rule require that branches are created and individual merges of the bugfix to each branch be made.

The goal of these rules is that people or organizations 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 REL1_20 in git.
