If you have it on, turn it '''off''' if you can. + +== MediaWiki 1.18 == +2011-11-24 + +This is the first stable release of the MediaWiki 1.18 branch. + +=== Summary of selected changes in 1.18 === + +Selected changes since MediaWiki 1.17 that may be of interest: + +* Some of the more commonly used MediaWiki extensions are now included in the + release tarball. These extensions are ConfirmEdit, Gadgets, Nuke, ParserFunctions, + Renameuser, Vector and WikiEditor. + +* Gender support has been improved, meaning user pages can display the correct gender + variant of "User" can now be used. + +* MediaWiki can now detect the camera orientation of an image from the Exif metadata, and + can rotate the image thumbnail appropriately. Metadata support has been generally + improved, and can now extract IPTC and XMP metadata. + +* Improved directionality support in 1.18 means that MediaWiki is better to use for + RTL users. + +* MediaWiki now supports protocol - relative URLs in links, interwiki targets and $wgServer + +* Math support has been removed from core + +=== Changes since 1.18.0rc1 === +* (bug 32228) regression in Special:Search which did not conserve profile on new search +* (bug 32460) Categories were improperly aligned in Simple and CologneBlue +* (bug 32412) TOC links on [[Special:EditWatchlist]] points to the fieldsets +* (bug 32582) Fix TOC show/hide link regression on IE 8 + +=== Changes since 1.18 beta 1 === +* (bug 31886) Wrong titles redirecting to Special:Badtitle in the 1.18 deployment. +* (bug 32051) Fix description for wlprop=sizes. +* (bug 31913) Special:MostLinkedTemplates had an incorrect GROUP BY clause + under Microsoft SQL. +* (bug 32100) installer complains about suhosin GET limit. +* (bug 31933) fix 1.18 regression in Monobook sidebar: huge spacing between portlets + on IE 7 and IE 8/9 in compatibility view. +* (bug 32126) Fix 1.18 regression in watchlist editor when items already removed + from watchlist. +* (bug 32183) remove the client-* classes added from user-agent-sniffing onto + the <html> element. +* (bug 29912) Unit tests break if parsertest tables are still present. +* (bug 31694) During installation, tabbing order (cursor focus) goes to logo + instead of 'continue'. +* (bug 29102) Upgrade fails "Unknown character set: 'mysql4". +* (bug 31990) justify paragraphs pref adds extra space to category listing. +* (bug 20148) Better title for [[Special:Disambiguations]] page. +* (bug 31502) TOC is missing on Special:EditWatchlist. +* (bug 32256) API list=search stops at first invalid result. +* (bug 32047) jquery.tablesorter.js: thead is before caption. +* (bug 29854) Store protocol-relative links twice in the externallinks table, + one with http: in el_index and once with https. +* (bug 31822) Error during upgrade due to output buffer reset in stdout. + +=== Configuration changes in 1.18 === +* The WantedPages::getSQL hook has been removed and replaced with + WantedPages::getQueryInfo. This may break older extensions. +* The SkinTemplateBuildContentActionUrlsAfterSpecialPage, + SkinTemplateContentActions and SkinTemplateTabs hooks have been removed in + favor of SkinTemplateNavigation and SkinTemplateNavigation::SpecialPage. +* $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. +* $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; +* OutputPage::isUserJsAllowed() no longer returns false when scripts are allowed + by the page, but $wgAllowUserJs is set to false. +* Pure "Skin" class based custom skins are no longer supported, all custom skins + should be put together using SkinTemplate and BaseTemplate or QuickTemplate. +* The transliteration for passwords in case they were migrated from an old + Latin-1 install (previous to MediaWiki 1.5) is now only done for wikis with + $wgLegacyEncoding set. +* (bug 27508) Add $wgSVGMetadataCutoff to limit the maximum amount of an SVG we + look at when finding metadata to prevent excessive resource usage. +* $wgSysopUserBans and $wgSysopRangeBans (deprecated in 1.17) are now removed. + Use $wgBlockCIDRLimit = array( 'IPv4' => 43, 'IPv6' => 128 ) to achieve the + same functionality as $wgSysopRangeBans; you can use the BlockIp hook to + replicate $wgSysopUserBans functionality. +* The options on the block form have been standardised such that checking a box + makes the block 'more serious'; so while "check to prevent account creation" + and "check to enable autoblock" remain the same, "check to allow user-talk + edit" is reversed to "check to *disable* user-talk edit", and "check to block + anon-only" becomes "check to block logged-in users too". The default settings + remain the same. +* Most of the field names on the Special:Block form have been changed, which + will probably break screen-scraping bots. +* (bug 26866) The 'trackback' right is no longer granted to sysops by default. + $wgUseTrackbacks is already false by default. +* (bug 17009) the hiddenStructure CSS class, a highly hackish way of at least + *appearing* to hide article elements, has been removed. Use the + ParserFunctions extension to actually remove unwanted elements from the + output. +* (bug 14202) $wgUseTeX has been superseded by the Math extension. To re-enable + math conversion after upgrading, obtain the Math extension from SVN or from + http://www.mediawiki.org/wiki/Extension:Math and add to LocalSettings.php: + require_once "$IP/extensions/Math/Math.php"; +* $wgProfiler is now a configuration array, see StartProfiler.sample for + details. +* $wgProfiling has been removed. +* The spyc library is now no longer included in phase3. +* (bug 28343) Unused preferences contextlines/contextchars have been removed +* $wgSkinExtensionFunctions has been removed. Use $wgExtensionFunctions instead. +* $wgProto has been removed. You now only need to set $wgServer to change the + URL protocol. +* $wgRateLimitsExcludedGroups (deprecated in 1.13) has been removed. +* $wgInputEncoding and $wgOutputEncoding (deprecated in 1.5) have now been removed. +* $wgAllowUserSkin (deprecated in 1.16) has now been removed. +* $wgExtraRandompageSQL (deprecated in 1.16) has now been removed. +* LogReader and LogViewer classes (deprecated in 1.14) have now been removed. +* (bug 26033) Added $wgArticleCountMethod to select the method to use to say + whether a page is an article or not. $wgUseCommaCount is now deprecated. +* $wgEnableDublinCoreRdf and $wgEnableCreativeCommonsRdf no longer work in core, + and the functionality has been moved to the relevant extensions. See + http://www.mediawiki.org/wiki/Extension:DublinCoreRdf and + http://www.mediawiki.org/wiki/Extension:CreativeCommonsRdf as appropriate. +* (bug 21107) Split error "customcssjsprotected" into separate messages for JS and CSS +* Removed $wgCheckCopyrightUpload from DefaultSettings, since the relevant feature + was removed in about 1.5. +* LogPageValidTypes, LogPageLogName, LogPageLogHeader and LogPageActionText + hooks have been removed. +* New hook "Collation::factory" to allow extensions to create custom + category collations. +* $wgGroupPermissions now supports per namespace permissions. +* $wgEnableAutoRotation enables or disables auto-rotation. Leaving it set to + null will cause MediaWiki to determine if auto-rotation is available. + +=== New features in 1.18 === +* BREAKING CHANGE: action=watch / action=unwatch now requires a token. +* BREAKING CHANGE: Article class hierarchy split into WikiPage (backend). + and Article (frontend) hierarchies. Several hooks now pass a WikiPage object instead + of an Article object. These hooks all use an $article paramater as documented in hooks.txt. + Extensions should be updated to account for this, though most won't require any changes. +* (bug 27860) Minor edit after clicking 'new section' tab + Now the "This is a minor edit" checkbox is not available when you + create a page or new section. +* (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. +* New hook ArticlePrepareTextForEdit added, called when preparing text to be + saved. +* New parser option PreSaveTransform added, allows the pre-save transformation + to be selectively disabled. +* Alternative to $wgHooks implemented, using the new Hooks class. +* Add width parameter to Special:Filepath to allow getting the file path of a + thumbnail. +* (bug 26870) Add size to {{filepath:}}. +* Upload warnings now show a thumbnail of the uploaded file. +* Introduced the edittools-upload message, which will be inserted under the + upload form instead of edittools if available. +* (bug 26285) Extensions will be automatically generated on upload if the user + specified a filename without extension. +* (bug 26851) Special:UserRights now allows to prefill the reason field +* New maintenance script to fix double redirects + (maintenance/fixDoubleRedirects.php). +* (bug 23315) New body classes to allow easier styling of special pages. +* (bug 27159) Make email confirmation code expiration time configurable. +* (bug 29047) CSS/JS for each user group is imported from MediaWiki:Group-sysop.js, + MediaWiki:Group-autoconfirmed.css, etc. +* (bug 24230) Uploads of ZIP types, such as MS Office or OpenOffice can now be + safely enabled. A ZIP file reader was added which can scan a ZIP file for + potentially dangerous Java applets. This allows applets to be blocked + specifically, rather than all ZIP files being blocked. +* (bug 2429) Allow selection of associated namespace in recent changes. +* (bug 26217) File size is now checked before uploading in HTML5 browsers. +* CSS stylesheet MediaWiki:Noscript.css is now loaded for users with JavaScript + disabled (enclosed in the head in a <noscript> tag). +* Added UserGetLanguageObject hook to change the language used in $wgLang. +* (bug 14645) When $wgMiserMode is on, expensive special pages are styled + differently (italicized by default) on Special:SpecialPages. +* Added $wgAggregateStatsID, which allows UDP stats to be aggregated over + several wikis. +* When $wgAllowMicrodataAttributes is true, all itemtypes are allowed, not just + the three that were defined in the original specification. +* (bug 14706) Added support for the Imagick PHP extension. +* (bug 18691) Added support for SVG rasterization using the Imagick PHP + extension. +* (bug 2581, bug 6834) Added links to thumbnail in several resolutions to the + file description page. The sizes are set by $wgImageLimits. +* (bug 28031) Add pageCount support to ArchivedFile. +* (bug 27924) PhpHttpRequest doesn't return response body if HTTP != 200. +* Added hook BitmapHandlerTransform to allow extension to transform a file + without overriding the entire handler. +* The parser now attempts to output markers for editsection tokens and defer the + rendering of them post-cache to reduce parser cache fragmentation and ensure + skin customizability of edit section links. +* (bug 24755) AuthPlugin auto-creation of local accounts can now be aborted by + other extensions by handling the 'AbortAutoAccount' hook, similar to the + 'AbortNewAccount' triggered by explicit account creations. (They are separate + to avoid loops and confusion; auth plugins like CentralAuth need to handle + AbortNewAccount separately. +* Special:ListFiles is now transcludable. +* (bug 13879) Special:Emailuser asks for suitable target user if called without. +* (bug 16956) IPTC and XMP metadata now extracted from images. +* (bug 23816) A tracking category is now added for any pages with broken images. +* (bug 23495) Allow createAndPromote.php to create non-sysop users. +* (bug 28916) A way to to toggle mw.config legacy globals settings from + LocalSettings.php has been created by introducing $wgLegacyJavaScriptGlobals. +* (bug 28503) Support for ircs:// URL protocols. +* (bug 26033) It is now possible to count all non-redirect pages in content + namespaces as articles. +* Images can now be embedded in an XML dump stream using backupDump.php + --include-files and can be imported using importDump.php --uploads; + furthermore, it can import files from the filesystem using --image-base-path. +* Three new hooks in Special:Undelete, 'UndeleteForm::showHistory', + 'UndeleteForm::showRevision' and 'UndeleteForm::undelete', so that extensions + may override the usage of PageArchive class and replace it with their own + class that extends PageArchive. +* (bug 28915) Implement QUnit test suite for MediaWiki JavaScript. + Also built-in support for distribution through a TestSwarm instance. +* (bug 29036) For cascade-protected pages, the mw-textarea-cprotected class is + added to the textarea on the edit form. +* mw.util.wikiScript has been implemented (like wfScript in GlobalFunctions.php) +* (bug 29067) Expose user.tokens (like we do user.options) in ResourceLoader. +* New 'Debug' hook used by wfDebug() and wfDebugLog(). +* (bug 27655) Require token for watching/unwatching pages) +* (bug 28904) (bug 29773) Update jQuery version from 1.4.4 to 1.6.2 (the latest version) +* (bug 29441) Expose CapitalLinks config in JS to allow modules to properly + handle titles on case-sensitive wikis. +* (bug 29397) Implement mw.Title module in core. +* In MySQL 4.1.9+ with replication enabled, fetch the slave lag from SHOW SLAVE + STATUS instead of SHOW PROCESSLIST. This ensures that lag is reported + correctly in the case where there are no write events occurring. Note that + the DB user now needs to have the REPLICATION CLIENT privilege if you are + using replication. +* Language codes in $wgDummyLanguageCodes are now excluded on localization + statistics (maintenance/language/transstat.php). +* (bug 29586) Make the (next 200) links on categories link directly to + the relevant section of the category. +* (bug 29109) Allow the automatic edit summary for redirect creation + show the first bit of the new redirect page. +* (bug 29723) mw.util.wikiGetlink() now defaults to wgPageName. +* (bug 29680) Add GetDefaultSortkey hook to override the default sortkey. +* (bug 16699) {{#language:}} accepts second parameter to specify the language in + which the language name is wanted.

If a group is removed from a user via Special:UserRights, + it will not automatically be re-added. Configuration is similar to + $wgAutopromote (see DefaultSettings.php). +* The PerformRetroactiveAutoblock hook was added to allow overriding or complementing + retroactive autoblock handling.

PostgreSQL, Oracle or SQLite can also be used, but +support for them is somewhat less mature. There is experimental support for IBM +DB2 and Microsoft SQL Server. + +The supported versions are: + +* MySQL 4.0 or later +* PostgreSQL 8.3 or later +* SQLite 3 +* Oracle 9.0.1 or later + +== 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 +repository, 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. + +For notes on 1.17.x and older releases, see HISTORY. + +== Online documentation == + +Documentation for both end-users and site administrators is available 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 mailing list is available for MediaWiki user support and discussion: + + 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. |
