RELEASE-NOTES-1.24

   1 Security reminder: If you have PHP's register_globals option set, you must
   2 turn it off. MediaWiki will no longer work with it enabled.

   4 == MediaWiki 1.24 ==
   5
   6 THIS IS NOT A RELEASE YET
   7
   8 MediaWiki 1.24 is an alpha-quality branch and is not recommended for use in
   9 production.
  10
  11 === Configuration changes in 1.24 ===
  12 * MediaWiki will no longer run if register_globals is enabled. It has been
  13   deprecated for 5 years now, and was removed in PHP 5.4. For more information
  14   about why, see <https://www.mediawiki.org/wiki/register_globals>.
  15 * MediaWiki now requires PHP's iconv extension. openSUSE users may need to
  16   install the php5-iconv package. Users of other systems may need to add
  17   extension=iconv.so to php.ini or recompile PHP without --without-iconv.
  18 * MediaWiki will no longer function if magic quotes are enabled. It has
  19   been deprecated for 5 years now, and was removed in PHP 5.4.
  20 * The server's canonical hostname is available as $wgServerName, which is
  21   exposed in both mw.config and ApiQuerySiteInfo.
  22 * Introduced $wgPagePropsHaveSortkey as a backwards-compatibility switch,
  23   for using the old schema of the page_props table, in case the respective
  24   schema update was not applied.
  25 * $wgSearchEverythingOnlyLoggedIn was removed as the 'searcheverything'
  26   user option was removed. Use $wgNamespacesToBeSearchedDefault instead or
  27   if you used to have $wgDefaultUserOptions['searcheverything'] = 1.
  28 * $wgMasterWaitTimeout has been deprecated.
  29 * $wgDBClusterTimeout has been removed.
  30 * $wgProxyKey has been removed. It is no longer used by MediaWiki core.
  31   Ensure $wgSecretKey is set in LocalSettings.php.
  32 * $wgExtraInterlanguageLinkPrefixes is a new configuration variable that
  33   contains an array of interwiki prefixes that should be treated as language
  34   prefixes (i.e. turned into interlanguage links when $wgInterwikiMagic is set
  35   to true).
  36 * $wgParserTestRemote has been removed.
  37 * $wgCountTotalSearchHits has been removed. If you're concerned about efficiency
  38   of search, you should use something like CirrusSearch instead of built in
  39   search.
  40 * Users in the 'sysop' group have access to Special:MergeHistory by default.
  41 * $wgFileStore was removed after having been deprecated in 1.17. Alternative
  42   configurations are $wgDeletedDirectory and $wgHashedUploadDirectory.
  43 * The deprecated $wgUseCommaCount variable has been removed.
  44 * $wgEnableSorbs and $wgSorbsUrl have been removed.
  45 * The UserCryptPassword and UserComparePassword hooks are no longer called. Any extensions
  46   using them must be updated to use the Password Hashing API.
  47 * $wgCompiledFiles has been removed.
  48 * $wgSortSpecialPages was removed, the listing on Special:SpecialPages is
  49   now always sorted.
  50 * $wgHTCPMulticastAddress, $wgHTCPMulticastRouting and $wgHTCPPort were removed.
  51 * $wgRC2UDPAddress, $wgRC2UDPInterwikiPrefix, $wgRC2UDPOmitBots, $wgRC2UDPPort
  52   and $wgRC2UDPPrefix have been removed.
  53 * The default password type for MediaWiki has been changed from MD5 to PBKDF2.
  54   Password hashes will automatically be updated as users log in. If necessary, the
  55   old MD5 hashing can be restored by changing $wgPasswordDefault to 'B'. In addition,
  56   there is a maintenance script wrapOldPassword.php that can wrap all passwords in
  57   PBKDF2 (or the hashing algorithm of your choice) if you don't want to wait for your
  58   users to log in.
  59 * $wgImportSources can now either be a regular array, or an associative map
  60   specifying subprojects on the interwiki map of the target wiki, or a mix of
  61   the two. Existing configurations will still work.
  62 * Users must be able to edit through a page's protection to be able to delete it.
  63 * The default thumb size ($wgDefaultUserOptions['thumbsize']) is now 300px, up from
  64   180px. If you have altered the number of entries in $wgThumbLimits for your wiki, you
  65   may need to adjust your default user settings to compensate for the index change.
  66
  67 === New features in 1.24 ===
  68 * Added a new hook, "WhatLinksHereProps", to allow extensions to annotate
  69   WhatLinksHere entries.
  70 * Added a new hook, "ContentGetParserOutput", to customize parser output for
  71   a given content object.
  72 * Deprecated the hook "ShowRawCssJs", use "ContentGetParserOutput" instead.
  73 * HTMLForm's HTMLTextField now supports the 'url' type.
  74 * HTMLForm fields may now be dynamically hidden based on the values of other
  75   fields in the form.
  76 * HTMLForm now supports multiple copies of an input field or set of input
  77   fields, e.g. the form may request "one or more usernames" without having to
  78   have the user enter delimited list of names into a text field.
  79 * Added a new hook, "SidebarBeforeOutput", to allow to edit the structure of
  80   the sidebar just before its display.
  81 * (bug 49156) Added the mediawiki.cookie ResourceLoader module, which wraps
  82   jquery.cookie so that getting/setting a cookie is syntactically and
  83   functionally similar to using the WebRequest::getCookie() and
  84   WebResponse::setcookie() methods.
  85 * (bug 44740) jQuery upgraded from 1.8.3 to 1.11.1. A new configuration option,
  86   $wgIncludejQueryMigrate, also loads the jQuery Migrate hack to let extensions
  87   and gadgets use the long-deprecated functions that were removed in jQuery 1.9.
  88   This option is turned off by default, and will be removed in MediaWiki 1.25.
  89 * (bug 47076) jQuery UI upgraded from 1.8.24 to 1.9.2.
  90 * Changes to content typography (fonts, etc.). See
  91   https://www.mediawiki.org/wiki/Typography_refresh for further information.
  92 * WikitextContent will now render redirects with the expected "redirect"
  93   header, rather than as an ordered list. Code calling Article::viewRedirect
  94   can probably be changed to no longer special-case redirects.
  95 * Header font set to a serif font stack. See
  96   https://www.mediawiki.org/wiki/Typography_refresh for further information.
  97 * (bug 65567) Added a new hook, "BeforeHttpsRedirect", to allow cancellation of
  98   the HTTP to HTTPS redirect due to forceHTTPS cookie, userRequires, etc. This
  99   is only for page views, since this hook doesn't affect UserLogin, OAuth,
 100   CentralAuth, etc. ATTENTION: This hook is likely to be removed soon due to
 101   overall design of the system.
 102 * (bug 17367) It is now possible to add pages to your watchlist from
 103   Special:UnwatchedPages without reloading the special page.
 104 * New methods setVolatile and isVolatile are added to PPFrame, so that
 105   extensions such as Cite.php can mark that their output is volatile and
 106   shouldn't be cached.
 107 * (bug 52817) Advanced search options are now saved on the search page itself,
 108   rather than in a dedicated pane in the preferences panel.
 109 * (bug 44591) The dropdown actions menu (little triangle next to page tabs) in
 110   the Vector skin has gained a label that should make it more discoverable.
 111 * MWCryptHKDF added for fast, cryptographically secure random number generation
 112   that won't deplete openssl's entropy pool.
 113 * ResourceLoader: File modules can now provide a skip function that uses an
 114   inline feature test to bypass loading of the module.
 115 * (bug 20210) Special pages may now provide autocompletion of their subpage
 116   names in search suggestions. Right now the only useful implementation is in
 117   Special:Log, but more are to come.
 118 * Special:MostLinkedTemplates is no longer limited to transclusions from the
 119   Template namespace.
 120 * Skins can now use 'remoteSkinPath' when defining ResourceLoader modules.
 121   This works the same as 'remoteExtPath' but is relative to the skins/ folder
 122   instead of the extensions/ folder.
 123 * Added the json2.js polyfill for the ES5 JSON.stringify and JSON.parse methods.
 124   Exposed as module "json" with a skip function to optimise loading.
 125 * Extensions and skins may now use 'namemsg' in $wgExtensionCredits in addition
 126   to 'name', to allow for the name to be localizable. 'name' should still be
 127   specified for backwards-compatibility and to define the path Special:Version
 128   uses to find extension license information.
 129 * Browser tests are now included to verify basic wiki functionality in developer
 130   environments. For details on running tests, see tests/browser/README.mediawiki.
 131 * Upgrade jStorage to v0.4.10.
 132 * {{!}} is now a magic word that produces the | character. This removes the need
 133   for Template:! for purposes such as passing pipes inside of parameters.
 134 * (bug 20790) The block log snippet on Special:Contributions and while
 135   editing user and user talk pages now works for IP range blocks.
 136 * (bug 9360) Added ability to change the page language for MediaWiki pages using
 137   Special:PageLanguage. All pages are set to wiki language by default.
 138   The feature needs to be enabled with $wgPageLanguageUseDB=true and
 139   permission needs to be set for 'pagelang'.
 140 * Upgrade Moment.js to v2.8.1.
 141 * (bug 67042) Added support for the HTML5 <rtc> tag for East Asian typography.
 142 * Upgrade Sinon.JS to 1.10.3.
 143 * Added the es5-shim polyfill for older or non-compliant javascript engines.
 144 * Upgrade jQuery Cookie to v1.3.1.
 145 * (bug 20476) Add a "viewsuppressed" user right to be able to view
 146   suppressed content but not suppress it ("suppressrevision" right).
 147 * (bug 66440) The MediaWiki web installer will now allow you to choose the skins
 148   to enable (from the ones included in download tarball) and decide which one
 149   should be the default.
 150 * (bug 68085, 68802) Links like [[localInterwikiPrefix:languageCode:pageTitle]],
 151   where localInterwikiPrefix is a member of the $wgLocalInterwikis array, will
 152   no longer be displayed in the sidebar when $wgInterwikiMagic is true. In a
 153   similar way, links like [[localInterwikiPrefix:File:Image.png]] and
 154   [[localInterwikiPrefix:Category:Hello]] will now render as regular links, and
 155   will not include the file or add the page to the category.
 156 * New special page, MyLanguages, to redirect users to subpages with localised
 157   versions of a page. (Integrated from Extension:Translate)
 158 * MediaWiki now supports multiple password types, including bcrypt and PBKDF2.
 159   The default type can be changed with $wgPasswordDefault and the type
 160   configurations can be changed with $wgPasswordConfig.
 161 * Skins can now define custom styles for default ResourceLoader modules using
 162   the $wgResourceModuleSkinStyles global. See the Vector skin for examples.
 163 * (bug 4488) There is now a preference to watch pages where the user has
 164   rollbacked an edit by default.
 165 * (bug 15484) Users will now be redirected to the login page when they need to
 166   log in, rather than being shown a page asking them to log in and having to click
 167   another link to actually get to the login page.
 168 * A JSONContent and JSONContentHandler were added for extensions to extend.
 169 * (bug 35045) Redirects to sections will now update the URL in browser's address
 170   bar using the HTML5 History API. When [[Dog]] redirects to [[Animals#Dog]],
 171   the user will now see "Animals#Dog" in their browser instead of "Dog#Dog".
 172
 173 === Bug fixes in 1.24 ===
 174 * (bug 50572) MediaWiki:Blockip should support gender
 175 * (bug 49116) Footer copyright notice is now always displayed in user language
 176   rather than content language (same as copyright notice for editing interface).
 177 * (bug 62258) A bug was fixed in File::getUnscaledThumb when a height
 178   restriction was present in the parameters. Images with both the "frame"
 179   option and a size specification set will now always ignore the provided
 180   size and display an unscaled image, as the documentation has always
 181   claimed it would.
 182 * (bug 39035) Improved Vector skin performance by removing collapsibleNav,
 183   which used to collapse some sidebar elements by default.
 184   This removes -list id suffixes like p-lang-list: instead of using things like
 185   #p-lang-list, you can do #p-lang .body ul.
 186 * (bug 890) Links in Special:RecentChanges and Special:Watchlist no longer
 187   follow redirects to their target pages.
 188 * Parser now dies early if called recursively, instead of producing subtle bugs.
 189 * (bug 14323) Redirect pages, when viewed with redirect=no, no longer hide the
 190   remaining page content.
 191 * (bug 52587) Maintenance script deleteBatch.php no longer follows redirects
 192   in the file namespace and delete the file on the target page. It will still
 193   however delete the redirect page.
 194 * (bug 22683) {{msgnw:}} and other uses of PPFrame::RECOVER_ORIG will correctly
 195   recover the original code of extension tags.
 196 * (bug 65757) MSSQL: Update script drops unnamed constraints to be prepared
 197   for future updates. Because it's doing so heuristically, it may fail or drop
 198   wrong constraints.
 199 * (bug 67870) wfShellExec() cuts off stdout at multiples of 8192 bytes.
 200 * $wgRunJobsAsync now works with private wikis (e.g. read requires login).
 201 * (bugs 57238, 65206) Blank pages can now be directly created.
 202 * (bug 69789) Title::getContentModel() now loads from the database when
 203   necessary instead of incorrectly returning the default content model.
 204
 205 === Web API changes in 1.24 ===
 206 * action=parse API now supports prop=modules, which provides the list of
 207   ResourceLoader modules that should be used to enhance the parsed content.
 208 * action=query&meta=siteinfo&siprop=interwikimap returns a new "protorel"
 209   field which is true iff protocol-relative urls can be used to access
 210   a particular interwiki map entry.
 211 * ApiQueryLogEvents now provides logpage, which is the page ID from the
 212   logging table, if ids are requested and the user has the permissions.
 213 * action=edit now requires that appendtext, prependtext, or section=new be used
 214   when using the 'redirect' parameter, to prevent clients accidentally
 215   overwriting the target page with the content of the redirect.
 216 * action=logevents will now return an error if both letitle and leprefix are
 217   specified.
 218 * action=logevents has a new parameter, lenamespace, to allow filtering by
 219   namespace.
 220 * action=expandtemplates has a new parameter, prop, and a new output format.
 221   The old format is still used if prop isn't provided, but this is deprecated.
 222 * meta=userinfo can now return the count of unread pages on the watchlist.
 223 * list=watchlist can now filter by unread status.
 224 * The deprecated action=parse&prop=languageshtml has been removed.
 225 * (bug 48071) action=setnotificationtimestamp no longer throws PHP or database
 226   errors when no pages are given.
 227 * (bug 60734) Actions that use ApiPageSet (e.g. purge, watch,
 228   setnotificationtimestamp) will now include continuation information when
 229   using a generator.
 230 * $wgAPIModules (and the related $wgAPIFormatModules, $wgAPIMetaModules,
 231   $wgAPIPropModules, and $wgAPIListModules settings) now allow API modules
 232   to be specified using a "module spec" array instead of a plain class name.
 233   A "module spec" is an associative array containing at least the 'class' key
 234   for the module's class, and optionally a 'factory' key for the factory function
 235   to use for the module. This is intended for extensions that want control over
 236   the instantiation of their API modules, to allow for proper dependency
 237   injection.
 238 * Removed 'props' and 'errors' from action=paraminfo, as they have extremely
 239   limited use and are generally inaccurate, unmaintained, and impossible to
 240   properly maintain. Also removed the corresponding methods from ApiBase and
 241   the 'APIGetPossibleErrors' and 'APIGetResultProperties' hooks.
 242 * Formats dbg, dump, txt, wddx, and yaml are now deprecated.
 243 * action=paraminfo now indicates when a parameter is specifying a submodule.
 244   Internally, a new param type 'submodule' is available to indicate this which
 245   automatically queries the list of submodule names from the ApiModuleManager.
 246 * The iwurl parameter to prop=iwlinks is deprecated in favor of iwprop=url, for
 247   parallelism with prop=langlinks.
 248
 249 === Languages updated in 1.24 ===
 250
 251 MediaWiki supports over 350 languages. Many localisations are updated
 252 regularly. Below only new and removed languages are listed, as well as
 253 changes to languages because of Bugzilla reports.
 254
 255 === Other changes in 1.24 ===
 256 * The deprecated jquery.delayedBind ResourceLoader module was removed.
 257 * The deprecated function mw.util.toggleToc was removed.
 258 * The Special:Search hooks SpecialSearchGo and SpecialSearchResultsAppend
 259   were removed as they were unused.
 260 * (bug 65477) User::pingLimiter() now has an additional profile point varying
 261   by action being used.
 262 * mediawiki.util.$content no longer supports old versions of the Vector,
 263   Monobook, Modern and CologneBlue skins that don't yet implement the "mw-body"
 264   and/or "mw-body-primary" class name in their html.
 265 * Added pp_sortkey column to page_props table, so pages can be efficiently
 266   queried and sorted by property value (bug 58032).
 267   See $wgPagePropsHaveSortkey if you want to postpone the schema change.
 268 * BREAKING CHANGE: All four built-in MediaWiki skins (Vector, MonoBook, Modern
 269   and Cologne Blue) were moved out of MediaWiki core to their own respective
 270   repositories. They will be installed with the release tarball, but you must
 271   install them separately if installing MediaWiki from source code. A warning
 272   message displayed until you do it should guide you through the process. See
 273   also <https://www.mediawiki.org/wiki/Manual:Skin_configuration>.
 274 * BREAKING CHANGE: Skins built for MediaWiki 1.15 and earlier that do not use
 275   the "headelement" template key are no longer supported. Setting
 276   $useHeadElement = false; is no longer supported and will not cause old keys
 277   like "headlinks", "skinnameclass", etc. to be defined.
 278 * The deprecated 'SpecialVersionExtensionTypes' hook was removed.
 279 * (bug 63891) Add 'X-Robots-Tag: noindex' header in action=render pages.
 280 * SpecialPage no longer supports the syntax for invoking wfSpecial*() functions.
 281   Special pages should subclass SpecialPage and implement the execute() method.
 282 * (bug 63755) The deprecated constants RC_MOVE and RC_MOVE_OVER_REDIRECT were
 283   removed.
 284 * Special:MostLinkedTemplates has been renamed to Special:MostTranscludedPages.
 285 * The skin autodiscovery mechanism has been deprecated and will be removed in
 286   MediaWiki 1.25. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery
 287   for migration guide for creators and users of custom skins that relied on it.
 288 * ResourceLoaderFileModule#getAllStyleFiles now returns all style files and all
 289   skin style files used by the module.
 290 * Removed getLang() from IContextSource and subclasses. (deprecated since 1.19)
 291 * Removed setLang() from subclasses of IContextSource. (deprecated since 1.19)
 292 * Removed WebRequest::escapeAppendQuery(). (deprecated since 1.20)
 293 * Removed info(), purge(), revert() and rollback() from the Article class; they
 294   have since become subclasses of the Action class. (deprecated since 1.19)
 295 * SearchEngineReplacePrefixesComplete hook was removed.
 296 * The "jquery.json" module has been deprecated. Use the "json" module instead.
 297 * Removed HTMLForm::addJS(). (deprecated since 1.18)
 298 * Removed LogEventsList::showHeader(). (deprecated since 1.19)
 299 * Removed ImageGalleryBase::useSkin(). (deprecated since 1.18)
 300 * Removed DatabaseMysqlBase::getLagFromProcesslist(). (deprecated since 1.19)
 301 * Removed LoadBalancer::closeConnecton(). (deprecated since 1.18)
 302 * Removed ApiBase::createContext(). (deprecated since 1.19)
 303 * BREAKING CHANGE: The undocumented Special{$this->getName()}BeforeFormDisplay
 304   set of hooks has been removed and replaced by a single new hook
 305   SpecialPageBeforeFormDisplay.
 306 * (bug 65781) Removed block warning on included {{Special:Contributions}}
 307 * Removed Skin::makeGlobalVariablesScript. (deprecated since 1.19)
 308 * Removed MWNamespace::isMain(). (deprecated since 1.19)
 309 * Removed Preferences::loadOldSearchNs(). (deprecated since 1.19)
 310 * Removed OutputPage::getStatusMessage(). (deprecated since 1.18)

 319 * Removed Language::getFallbackLanguageCode(). (deprecated since 1.19)
 320 * Removed WikiPage::isBigDeletion(). (deprecated since 1.19)
 321 * Removed MWInit class which contained functions related to a now discontinued
 322   PHP compiler called hphpc. (deprecated since 1.22)
 323 * ApiResult::enableSizeCheck() and disableSizeCheck() are now obsolete.
 324 * Removed ResourceLoaderGetStartupModules hook. (deprecated since 1.23)
 325 * Removed getFormFields(), onSubmit() and onSuccess() from FormlessAction, as
 326   these were meant specifically for FormAction instead.
 327 * Removed Action::execute().
 328 * Removed AjaxAddScript which has been obsolete since ResourceLoader and
 329   is unused by any modern extension.
 330 * Removed maintenance/nextJobDB.php; no longer in use.
 331 * Removed global function wfViewPrevNext(). (deprecated since 1.19)
 332 * Removed global function xmlsafe() from Export.php. (moved to OAIRepo extension)
 333 * Removed Title::userCanRead(). (deprecated since 1.19)
 334 * Removed maintenance script importTextFile.php. Use edit.php script instead.
 335 * A _from_namespace field has been added to the templatelinks, pagelinks,
 336   and filelinks tables. Run update.php to apply this change to the schema.
 337 * Removed File::sha1Base36(). (deprecated since 1.19)
 338 * Removed File::getPropsFromPath(). (deprecated since 1.19)
 339 * Removed functions blockedPage(), noCreatePermission(), readOnlyPage() and

 341 * Removed functions getContent(), getPreloadedText(), mergeChangesInto() and
 342   setPreloadedText() from EditPage.php. (deprecated since 1.21)
 343 * Removed global functions wfArrayLookup(), wfArrayMerge(), wfDebugDieBacktrace()
 344   and wfTime(). (deprecated since 1.22)
 345 * Microsoft Internet Explorer 6 is now a "grade C" browser, meaning that
 346   JavaScript is no longer executed in this browser. The IEFixes script, which
 347   existed purely to provide support for MSIE versions below 7 and which was
 348   conditionally loaded for those browsers, was also removed.
 349 * Action::checkCanExecute() no longer has a return value.
 350 * Removed cleanupForIRC(), loadFromCurRow(), newFromCurRow(), notifyRC2UDP()
 351   and sendToUDP() from RecentChange.php. (deprecated since 1.22)
 352 * Removed EnhancedChangesList::arrow(), sideArrow(), downArrow(), spacerArrow().
 353 * Removed Xml::namespaceSelector(). (deprecated since 1.19)
 354 * Removed WikiPage::estimateRevisionCount. (deprecated since 1.19)

 404 == Compatibility ==
 405
 406 MediaWiki 1.24 requires PHP 5.3.2 or later.
 407
 408 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 409 support for them is somewhat less mature. There is experimental support for
 410 Oracle and Microsoft SQL Server.
 411
 412 The supported versions are:
 413
 414 * MySQL 5.0.2 or later
 415 * PostgreSQL 8.3 or later
 416 * SQLite 3.3.7 or later
 417 * Oracle 9.0.1 or later
 418 * Microsoft SQL Server 2005 (9.00.1399)
 419
 420 == Upgrading ==
 421
 422 1.24 has several database changes since 1.23, and will not work without schema
 423 updates. Note that due to changes to some very large tables like the revision
 424 table, the schema update may take quite long (minutes on a medium sized site,
 425 many hours on a large site).
 426
 427 If upgrading from before 1.11, and you are using a wiki as a commons
 428 repository, make sure that it is updated as well. Otherwise, errors may arise
 429 due to database schema changes.
 430
 431 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 432 new database fields are filled with data.
 433
 434 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 435 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 436 with MediaWiki 1.21.
 437
 438 Don't forget to always back up your database before upgrading!
 439
 440 See the file UPGRADE for more detailed upgrade instructions.
 441
 442 For notes on 1.23.x and older releases, see HISTORY.
 443
 444 == Online documentation ==
 445
 446 Documentation for both end-users and site administrators is available on
 447 MediaWiki.org, and is covered under the GNU Free Documentation License (except
 448 for pages that explicitly state that their contents are in the public domain):
 449
 450         https://www.mediawiki.org/wiki/Documentation
 451
 452 == Mailing list ==
 453
 454 A mailing list is available for MediaWiki user support and discussion:
 455
 456         https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 457
 458 A low-traffic announcements-only list is also available:
 459
 460         https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 461
 462 It's highly recommended that you sign up for one of these lists if you're
 463 going to run a public MediaWiki, so you can be notified of security fixes.
 464
 465 == IRC help ==
 466
 467 There's usually someone online in #mediawiki on irc.freenode.net.
