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.
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.
The stable version is even more stable than the beta. It will receive maintenance and security fixes until it becomes a legacy version.
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).
Older versions are no longer supported and will not receive security fixes; see Ciclo de vida de las versiones.
