O MediaWiki se esforça para manter ampla compatibilidade entre as versões, e com uma gama de softwares atuais e antigos. Ao mesmo tempo, não será possível manter a compatibilidade com o software antigo indefinidamente, devido a características do mais recente desenvolvimento da MediaWiki, e visto que a base de código está em constante evolução.


Software necessário para executar o MediaWiki

This sections provides an overview of the software required on the server to run MediaWiki.

The latest stable branch of MediaWiki (1.32) runs on any version of PHP 7.0.13 to PHP 7.2. PHP 7.2 support is available in MediaWiki 1.31 and newer.

MediaWiki is not fully compatible with PHP 7.3 yet. [1]

Since 2014, Wikimedia Foundation runs MediaWiki on HHVM, but plans to migrate to PHP7,[2] after which point MediaWiki will likely drop HHVM compatibility.[3] MediaWiki requires either PHP 7.0+ or HHVM from release 1.31 onwards.[4]

Features that are not used on Wikimedia wikis might not work correctly on HHVM.

MediaWiki 1.27 will continue to receive security updates until its respective end-of-life date (see version lifecycle) and retain compatibility with its respective versions of PHP.

O MediaWiki é compatível com muitos servidores de banco de dados, embora para o MySQL o suporte é melhor. (O MariaDB também pode ser usado.)

O status de suporte para outros softwares de banco de dados varia de fraco para razoável. MediaWiki provides database abstraction layers for PostgreSQL and SQLite, which are generally well-maintained. The included abstraction layers for Oracle and Microsoft SQL Server are essentially unmaintained and are unlikely to work out of the box.

Running MediaWiki on anything other than MySQL or MariaDB is not recommended for production use at this point.

Servidor Web

MediaWiki é amplamente compatível com todos os principais servidores web que podem invocar PHP. O Apache é o mais usado e testado.

Apache is the most used and tested. Nginx is a good choice as well.

MediaWiki extensions

As long as an extension is properly maintained (which you can see at the top of the infobox on its description page), the master branch of the extension should be compatible with the master branch of MediaWiki. For determining compatibility with older MediaWiki versions, there are two common policies used by extensions:

  • master (key: master): the master branch of the extension is compatible with both current and older versions of MediaWiki. Back-compatibility hacks are added to the extension source code as needed.
  • release branches (key: rel): For every MediaWiki release, there is a corresponding branch in the extension. So e.g. if you use MediaWiki 1.32, you should use the REL1_32 branch of the extension.

The compatibility policy field of the {{Extension}} infobox tells which policy is used by a given extension. Use the respective keys indicated above to specify the information.

Some extensions may have more specific compatibility policies, for instance:


General information

There is an ever-growing number of different web browsers in the world.

Too many to actively test and support each one.

Isto descreve as nossas práticas em todo o suporte ao navegador.

Each tier represents a different category of browsers.

Modern (Grade A)

This group (also known as Grade A) represents the highest level of support. Features take advantage of capabilities in modern browsers, while allowing a graceful fallback for older browsers. All features provided by the software (whether or not in a degraded form) must work in these browsers.

Browsers in this category are known (listed below) and actively tested against. Problems users perceive in these browsers are addressed with high priority.

Basic (Grade C)

O suporte de nível básico fornece a funcionalidade principal da plataforma MediaWiki. Nossas respostas o HTTP são compatíveis com os navegadores (por exemplo, o HTTP apresenta, e contamos com isso, codificação de caracteres, e formatos de imagem usados ​​no conteúdo; deve funcionar nesses navegadores). No front-end, isso significa que o conteúdo é apresentado de forma legível, e até certo ponto as ações do usuário podem ser realizadas.

Browsers nesta categoria são conhecidos e identificados por meio de uma lista negra no módulo de inicialização.

Unknown (Grade X)

This group (also known as Grade X) represents all other browsers. This includes browsers that are no longer developed or browsers not popular enough to justify the added maintenance cost for software development.

Browsers not included in any other group belong to this category.

Problems users perceive in these browsers only are given low priority.

MediaWiki handles these browsers the same as Modern (Grade A) browsers and they are thus assumed to be capable. This principle provides various important benefits:

  • New versions of modern browsers may temporarily be considered Unknown if they are not yet tested against by us. Treating Unknown browsers as capable ensures optimal user experience in these browsers.
  • Users of new and evolving browsers are given a chance to have a modern experience.
  • Users of less popular browsers based on, or derived from, known modern browsers are not negatively impacted (e.g. Iceweasel).

In practice the only difference between Unknown and Modern browsers is that we don't actively test against Unknown browsers.

These browsers are given the full feature set.

Matriz de suporte do navegador


While the principles and different grades described above apply to MediaWiki core and extensions alike, the below browser support matrix applies to MediaWiki core only (and extensions that decide to follow it). Individual extensions may have their own support matrix distributing browsers among the different levels of support. See also analytics user agent breakdown dashboard for desktop.

Navegadores: Chrome Internet Explorer Edge Firefox Safari Opera iOS Android
Modern Atual e anterior 11+[5][6][7][8] TBC Atual e anterior 5.1+ 15+ 6.1+ 4.1+
Basic 1+ 6+ TBC 3.0+ 3.0+ 15.0+ 5.0+ 2.0+
Unknown All other browsers


(Last updated: March 2017)

The Web team at the Wikimedia Foundation uses a different support matrix for mobile-specific skins e.g. Minerva skin and/or extensions designed to run on mobile devices e.g. MobileFrontend. The support matrix is compiled from the data provided by the analytics user agent breakdown dashboard. Where browser usage is over 5% a modern experience is supported. Basic support is provided for anything over 0.1% over the 12 months. In mobile we strive to provide a Grade B. Users of grade B may or may not get JavaScript and we do not test to the same level as A, thus we prioritize bug fixes lower.
