Versión
Hay varias versiones de MediaWiki disponibles para descargar en cualquier momento. Las extensiones también pueden tener distintos estados de lanzamiento.
Núcleo
Versión en desarrollo
The development version is available by downloading from Git. It is generally quite stable, and there are some wikis that run from the trunk.
Versión Beta
The beta version has been reviewed and is thought to be good. It is more stable than the development version. However, you are encouraged to report any bugs you encounter to Phabricator, so that they can be fixed for the officially stable version.
Versión estable
The stable version is even more stable than the beta. It will receive maintenance and security fixes until it becomes a legacy version.
Versión preexistente
The legacy version is even more stable than the beta. It is like a stable version but will only receive security fixes during the period of one year after its release. Some legacy versions are designated as long-term supported (LTS).
Versiones antiguas
Older versions are no longer supported and will not receive security fixes; see Ciclo de vida de las versiones.
Extensiones
Extensions can be classified as unstable, experimental, beta, stable, or unknown; see here for more details. See also Compatibility#MediaWiki extensions.
