Version lifecycle/pt-br

O MediaWiki opera em um modelo de desenvolvimento de "integração contínua", onde as mudanças de software são enviadas diretamente para sites da Wikimedia como a Wikipédia em uma base regular.

Em teoria, os novos grandes lançamentos são emitidos numa base semestral, e pacotes de lançamento continuar a receber atualizações de segurança para até um ano a partir da primeira versão. Devido a limitações de tempo e de refatoração rápida da base de código, não podemos apoiar lançamentos obsoletos para sempre, e as atualizações de segurança e críticas não são aplicadas aos lançamentos que atingiram o término do status de vida.

O gerenciador de lançamento recomenda enfaticamente que os operadores wiki se inscrevam na lista de discussão, que recebe a notificação de todos os lançamentos, e garante que o seu wiki executa a mais atualizada versão do software possível. Estes anúncios também são destacados para  e.

Versões e seu fim de vida
For the planned upcoming release cycles see this page.

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

Release Policy

 * 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 is supported until May 2015. 1.23 will be released the year before that so that people will have 1.23 available as an LTS to move to and a year to make the transition.


 * Releases 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 comes out, we'll have an announcement for 1.19 users letting them know what changes they can expect in 1.23.


 * Point releases will be made periodically. 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. Extension:UniversalLanguageSelector doesn't support current LTS).

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.
