|Allow filtering by change tag in recentchanges, history, etc.
|Introduced in version:||1.15.0 (r47767)
|Removed in version:||still in use
Allow filtering by change tag in recent changes, page history, user contributions and new pages.
Has no effect if no tags are defined in the valid_tag database table and there are no extensions enabled which have defined their own tags.
Extensions can define and store their own tags and make them available by using the ListDefinedTags hook.
Extension:AbuseFilter does this: when creating one or more filters which tag edits for review, filtering by change tag in recentchanges, etc. is enabled when $wgUseTagFilter is set to true.
