= MediaWiki release notes = Security reminder: MediaWiki does not require PHP's register_globals setting since version 1.2.0. If you have it on, turn it *off* if you can. == MediaWiki 1.18 == THIS IS NOT A RELEASE YET MediaWiki is now using a "continuous integration" development model with quarterly snapshot releases. The latest development code is always kept "ready to run", and in fact runs our own sites on Wikipedia. Release branches will continue to receive security updates for about a year from first release, but nonessential bugfixes and feature developments will be made on the development trunk and appear in the next quarterly release. Those wishing to use the latest code instead of a branch release can obtain it from source control: http://www.mediawiki.org/wiki/Download_from_SVN === Configuration changes in 1.18 === * The WantedPages::getSQL hook has been removed and replaced with WantedPages::getQueryInfo . This may break older extensions. * $wgUseCombinedLoginLink controls whether to output a combined login / create account link in the personal bar, or to output separate login and create account links * Skin names are no longer created based on a ucfirst version of the key in $wgValidSkinNames but now the value. This means for $wgValidSkinNames["monobook"] = "MonoBook"; the skin loader will no longer try loading SkinMonobook and will instead load SkinMonoBook. * The parser now attempts to output markers for editsection tokens and defer the rendering of them so skin and language specific markup does not need to be saved inside the parser cache note that this changes the cache key making all old entries in the parser cache invalid you can set $wgUseEditSectionTokens to false to disable this and keep your old parser cache entries. Note that this feature should reduce parser cache fragmentation when enabled. * $wgMaxUploadSize may now be set to an array to specify the upload size limit per upload type. * $wgAPICacheHelp added in 1.16 is now removed. To disable API help caching, set $wgAPICacheHelpTimeout = 0; === New features in 1.18 === * Added a special page, disabled by default, that allows users with the 'disableaccount' privilege to permanently deactivate user accounts. * (bug 8130) Query pages should limit to content namespaces, not just main namespace * Search suggestions (other than in the Vector skin) will now use the HTML5 datalist feature where supported, currently only Firefox 4. * Special:Contribs now redirects to Special:Contributions * (bug 6672) Images are now autorotated according to their EXIF orientation. This only affects thumbnails; the source remains unrotated. * (bug 25708) Update case mappings and normalization to Unicode 6.0.0 === Bug fixes in 1.18 === * (bug 23119) WikiError class and subclasses are now marked as deprecated * (bug 10871) Javascript and CSS pages in MediaWiki namespace are no longer treated as wikitext on preview. * (bug 22753) Output from update.php is more clear when things changed, entries indicating nothing changed are now all prefixed by "..." * Page existence is now not revealed (in the colour of the tabs) to users who cannot read the page in question. * (bug 19006) {{REVISIONUSER}} no longer acts like {{CURRENTUSER}} in some cases * (bug 16019) $wgArticlePath = "/$1" no longer breaks API edit/watch actions * (bug 18372) File types blacklisted by $wgFileBlacklist will no longer be shown as "Permitted file types" on the upload form * (bug 26379) importImages.php gives more descriptive error message on failure. * (bug 26410) + signs are no longer treated as spaces in internal links if link has a % sign in it. * (bug 26412) Search results headers no longer show a bogus edit link. * (bug 26540) Fixed wrong call to applyPatch in MysqlUpdater * (bug 26574) Added 'upload' to $wgRestrictionTypes, allowing upload protected pages to be queried via the API and Special:ProtectedPages, and allowing disabling upload protection by removing it from $wgRestrictionTypes. * If an edit summary exceeds 250 bytes and is truncated, add an ellipse * (bug 26638) Database error pages display correctly in RTL languages * (bug 26187) Confirmrecreate no longer parses the edit summary * (bug 25506) Exception is thrown if OutputPage::parse is called inside a tag hook, which would reset parser state * (bug 26208) Mark directionality of some interlanguage links * (bug 26034) Make the "View / Read" tab in content_navigation style tabs remain selected when the action is "purge". === API changes in 1.18 === * (bug 26339) Throw warning when truncating an overlarge API result * (bug 14869) Add API module for accessing QueryPage-based special pages * (bug 14020) API for Special:Unwatchedpages * (bug 24287) Wrap API Help output at 100 characters * Add a realname uiprop option to query=userinfo so a user's realname can be extracted * Add a &watchuser option to ApiBlock * (bug 26541) Generator-ise ApiQueryRecentChanges * action=parse now correctly returns an error for nonexistent pages * (bug 25767) Add userrights properties to allusers and users query lists * (bug 26558) list=allusers auprop=groups does not list groups a user is automatically a member of * (bug 26559) list=allusers auprop=rights does not match list=users usprop=rights * (bug 26560) On allusers if limit < total number of users, last user gets duplicate * (bug 25135) add "normalized" to action=parse * (bug 26460) Add support for listing category members by category pageid * (bug 26482) add a imimages param to prop=images * (bug 26498) allow LinksUpdate with API * (bug 26485) add a elextlinks param to prop=extlinks * (bug 26483) add a iwtitles param to prop=iwlinks * (bug 26484) add a lltitles param to prop=langlinks * (bug 26480) add a pppageprops param to prop=pageprops * (bug 26650) Remove $wgAPICacheHelp in favour of $wgAPICacheHelpTimeout === Languages updated in 1.18 === MediaWiki supports over 330 languages. Many localisations are updated regularly. Below only new and removed languages are listed, as well as changes to languages because of Bugzilla reports. == Compatibility == MediaWiki 1.18 requires PHP 5.1 (5.2 recommended). PHP 4 is no longer supported. MySQL 3.23.x is no longer supported; some older hosts may need to upgrade. At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases. == Upgrading == 1.18 has several database changes since 1.17, and will not work without schema updates. If upgrading from before 1.11, and you are using a wiki as a commons reposito- ry, make sure that it is updated as well. Otherwise, errors may arise due to database schema changes. If upgrading from before 1.7, you may want to run refreshLinks.php to ensure new database fields are filled with data. If you are upgrading from MediaWiki 1.4.x or earlier, some major database changes are made, and there is a slightly higher chance that things could break. Don't forget to always back up your database before upgrading! See the file UPGRADE for more detailed upgrade instructions. === Caveats === Some output, particularly involving user-supplied inline HTML, may not produce 100% valid or well-formed XHTML output. Testers are welcome to set $wgMimeType = "application/xhtml+xml"; to test for remaining problem cases, but this is not recommended on live sites. (This must be set for MathML to display properly in Mozilla.) For notes on 1.17.x and older releases, see HISTORY. === Online documentation === Documentation for both end-users and site administrators is currently being built up on MediaWiki.org, and is covered under the GNU Free Documentation License (except for pages that explicitly state that their contents are in the public domain) : http://www.mediawiki.org/wiki/Documentation === Mailing list === A MediaWiki-l mailing list has been set up distinct from the Wikipedia wikitech-l list: http://lists.wikimedia.org/mailman/listinfo/mediawiki-l A low-traffic announcements-only list is also available: http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce It's highly recommended that you sign up for one of these lists if you're going to run a public MediaWiki, so you can be notified of security fixes. === IRC help === There's usually someone online in #mediawiki on irc.freenode.net
