MediaWiki

MediaWiki was a starting point for Wikipedia, but has now evolved into its stand-alone version.

Written in PHP, MediaWiki allows easy real-time editing of Web pages, just like on all WikiMedia projects.

Support for themes, wiki text, page history, diff views, and WYSIWYG editing is also included.

What is new in this release:

• Change tags can now be hidden in the interface by disabling the associated "tag-<id>" interface message.
• ':' (colon) is now invalid in usernames for new accounts. Existing accounts are not affected.
• Added a new hook, 'LogException', to log exceptions in nonstandard ways.
• Revive the 'SpecialSearchResultsAppend' hook which occurs after the list of search results are rendered. The initial use case is to append a "give us feedback" link beneath the search results.
• Added a new hook, 'RejectParserCacheValue', which allows extensions to reject an otherwise-successful parser cache lookup. The intent is to allow extensions to manage the eviction of archaic HTML output from the cache.
• (T68699) The expiration of the UserID and Token login cookies ($wgExtendedLoginCookieExpiration) can be configured independently of the expiration of all other cookies ($wgCookieExpiration).
• (T50519) Support for generating JPEG/PNG thumbnails from WebP images added if ImageMagick is used as image scaler ($wgUseImageMagick = true). Uploading of WebP images still disabled by default. Add $wgFileExtensions[] = 'webp'; to LocalSettings.php to enable uploading of WebP images.
• Added new hooks 'EnhancedChangesListModifyLineData' & 'EnhancedChangesListModifyBlockLineData', to modify the data used to build lines in enhanced recentchanges and watchlist.
• Callers needing fast light-weight data stores use $wgMainStash to select the store type from $wgObjectCaches. The default is the local database.
• Interface message overrides in the MediaWiki namespace will now be cached in memcached and APC (if available), rather than memcached and local files.
• Added a new hook, 'RandomPageQuery', to allow modification of the query used by Special:Random to select random pages.
• $wgTransactionalTimeLimit was added, which controls the request time limit for potentially slow POST requests that need to be as atomic as possible.
• ResourceLoader now loads all scripts asynchronously. The top-queue and startup modules are no longer synchronously loaded.
• 'mediawiki.ui.button' styles are no longer unconditionally loaded on every page. During the deprecation period, the styles will only be loaded on pages which contain 'mw-ui-button' in their HTML. Starting in 1.28, the styles will only be loaded if explicitly required.

What is new in version 1.25.3:

• Added new hook WatchlistEditorBeforeFormRender, allowing subscribers to manipulate the list of pages and/or preload lots of data at once.
• Added new argument &$link in hook WatchlistEditorBuildRemoveLine, allowing the link to the title to be changed.
• Added a new hook, "WhatLinksHereProps", to allow extensions to annotate WhatLinksHere entries.
• Added a new hook, "ContentGetParserOutput", to customize parser output for a given content object.
• Deprecated the hook "ShowRawCssJs", use "ContentGetParserOutput" instead.
• HTMLForm's HTMLTextField now supports the 'url' type.
• HTMLForm fields may now be dynamically hidden based on the values of other fields in the form.
• HTMLForm now supports multiple copies of an input field or set of input fields, e.g. the form may request "one or more usernames" without having to have the user enter delimited list of names into a text field.
• Added a new hook, "SidebarBeforeOutput", to allow to edit the structure of the sidebar just before its display.
• (bug 49156) Added the mediawiki.cookie ResourceLoader module, which wraps jquery.cookie so that getting/setting a cookie is syntactically and functionally similar to using the WebRequest::getCookie() and WebResponse::setcookie() methods.
• (bug 44740) jQuery upgraded from 1.8.3 to 1.11.1. A new configuration option, $wgIncludejQueryMigrate, also loads the jQuery Migrate hack to let extensions and gadgets use the long-deprecated functions that were removed in jQuery 1.9.
