Details
The current version of MediaWiki (e.g, "1.40.0"). You shouldn't need to set this option; it is used internally.
MW_VERSION
| MediaWiki version: | ≥ 1.35 |
Starting with MediaWiki 1.35, $wgVersion is deprecated, and replaced with the MW_VERSION constant.
It is also available in MediaWiki 1.31.7, 1.33.3 and 1.34.1, though this should not be relied on as its presence is required for some release tools.
$wgVersion will continue to function the same as before in those versions.
Example code
If you're implementing a new feature that only works in MediaWiki 1.19 or later, but you want to maintain backwards compatibility, you could use a test such as the following:
$oldVersion = version_compare( $wgVersion, '1.18', '<=' );
if ( $oldVersion ) {
# <translate nowrap><!--T:9--> Do stuff for MediaWiki 1.18 and older</translate>
} else {
# <translate nowrap><!--T:10--> Do stuff for MediaWiki 1.19 and newer</translate>
}
However, it is typically recommended that you use feature detection to see whether the method or class you wish to use is available instead of depending upon raw version strings.
