Module documentation

[view] [edit] [history] [purge]

The main entrypoint is the get function.

First parameter is the release type, which can be one of the following:

• stable
• legacy
• lts
• beta
• alpha

Second parameter is the format, which can be one of the following:

• version
• branch
• git
• date

Note that alpha and beta only work with branch, the behavior of other output formats is undefined.

Examples

• {{#invoke:Version|get|alpha|branch}}: 1.45
• {{#invoke:Version|get|beta|branch}}: 1.44
• {{#invoke:Version|get|stable|version}}: 1.43.0
• {{#invoke:Version|get|stable|branch}}: 1.43
• {{#invoke:Version|get|stable|git}}: REL1_43
• {{#invoke:Version|get|stable|date}}: 2024-12-21
• {{#invoke:Version|get|lts|version}}: 1.43.0
• {{#invoke:Version|get|legacy|version}}: 1.42.4
• {{#invoke:Version|get|legacylts|version}}: 1.39.11

That said, you probably want to use one of the wrapper templates in Category:MediaWiki version information templates instead of calling this module directly.
