Details

The current version of MediaWiki (e.g, "1.41.1"). You shouldn't need to set this option; it is used internally.

MW_VERSION

<td class="mw-version-versionbox" title="<translate nowrap> The latest stable version is <tvar name=1>1.41</tvar></translate>">

<translate> ≥</translate> 1.35

<translate> MediaWiki version:</translate>

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:

global $wgVersion;
$oldVersion = version_compare( $wgVersion, '1.18', '<=' );
if ( $oldVersion ) {
    # Do stuff for MediaWiki 1.18 and older
} else {
    # Do stuff for MediaWiki 1.19+
}

<td class="mw-version-versionbox" title="<translate nowrap> The latest stable version is <tvar name=1>1.41</tvar></translate>">

<translate> ≥</translate> 1.35

<translate> MediaWiki version:</translate>

$oldVersion = version_compare( MW_VERSION, '1.39', '<' );
if ( $oldVersion ) {
    #  Do stuff for MediaWiki 1.35 - 1.38
} else {
    #  Do stuff for MediaWiki 1.39+
}

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.
