RELEASE-NOTES-1.32

   1 == MediaWiki 1.32 ==
   2
   3 THIS IS NOT A RELEASE YET
   4
   5 MediaWiki 1.32 is an alpha-quality branch and is not recommended for use in
   6 production.
   7
   8 === Configuration changes in 1.32 ===
   9 * (T115414) The $wgEnableAPI and $wgEnableWriteAPI settings, deprecated in 1.31,
  10   have been removed.
  11 * The $wgUseAjax setting, deprecated in 1.31, is now ignored.
  12 * The $wgSiteSupportPage setting, unused since 1.5, was removed.
  13 * The $wgBrowserBlacklist setting, deprecated in 1.30, was removed.
  14 * The default quality of JPEG thumbnails generated by GD was reduced from 95 to
  15   80. The quality of JPEG thumbnails is now configurable through the new setting
  16   $wgJpegQuality (default 80). This aligns the quality to what ImageMagick uses.
  17 * $wgExperimentalHtmlIds, deprecated since 1.30, has been removed. The
  18   'html5-legacy' value for $wgFragmentMode is no longer accepted.
  19 * The experimental Html5Internal and Html5Depurate tidy drivers were removed.
  20   RemexHtml, which is the default, should be used instead.
  21 * (T135963) You can now define a Content Security Policy for your wiki. This
  22   adds a defense-in-depth feature to stop an attacker who has found a bug in
  23   the parser allowing them to insert malicious attributes. Disabled by default,
  24   you can configure this via $wgCSPHeader and $wgCSPReportOnlyHeader.
  25 * New configuration variable has been added: $wgCookieSetOnIpBlock.
  26   This determines whether to set a cookie when an IP user is blocked. Doing so
  27   means that a blocked user, even after moving to a new IP address, will still
  28   be blocked.
  29 * The archive table's ar_rev_id field is now unique.
  30 * Special:BotPasswords now requires reauthentication.
  31 * (T194414) The default watchlist view time has been increased from 3 to 7 days.
  32 * The right to edit sitewide Javascript (e.g. MediaWiki:Common.js), CSS or JSON
  33   was separated from 'editinterface' and is available under
  34   'editsitejs'/'editsitecss'/'editsitejson'. Having 'editinterface' is still
  35   necessary to edit such pages.
  36 * A new user group, 'interface-admin', is added for controlling access to
  37   sitewide CSS/JS (and editing other users' CSS/JS). No other group has
  38   'editsitecss', 'editusercss', 'editsitejs' or 'edituserjs' by default.
  39 * A new grant group, 'editsiteconfig', is added for granting the above rights.
  40 * The $wgPasswordSenderName setting, ignored since 1.23 by MediaWiki and almost
  41   all extensions, is no longer set at all. Instead, you can modify the system
  42   message `emailsender`.
  43 * A new configuration setting, $wgRawHtmlMessages, is added, for listing
  44   messages which are displayed as raw HTML.
  45
  46 === New features in 1.32 ===
  47 * (T112474) Generalized the ResourceLoader mechanism for overriding modules
  48   using a particular page during edit previews.
  49 * (T12331) You can now log page creation events by setting $wgPageCreationLog
  50   to true.
  51 * Added 'ApiParseMakeOutputPage' hook.
  52 * (T174313) Added checkbox on Special:ListUsers to display only users in
  53   temporary user groups.
  54 * (T152462) A cookie can now be set when an IP user is blocked to track that
  55   user if they move to a new IP address. This is disabled by default.
  56 * (T194950) Added 'ApiMaxLagInfo' hook.
  57 * SpecialPage::checkLoginSecurityLevel() will now preserve POST data when
  58   reauthenticating.
  59 * FormSpecialPage::execute() will now call checkLoginSecurityLevel() if
  60   getLoginSecurityLevel() returns non-false.
  61 * The 'ImageBeforeProduceHTML' hook is now passed three new parameters, $parser,
  62   &$query and &$widthOption, allowing extensions even finer control over the
  63   resulting HTML code.
  64 * Added new 'ArticleShowPatrolFooter' hook, which allows extensions to determine
  65   if the [mark as patrolled] link should be shown at the footer of patrollable
  66   pages.
  67 * The array of hidden options ($opts) passed to the 'SpecialSearchPowerBox' hook
  68   is now passed by reference, allowing extensions to modify or even unset it.
  69 * Added new 'OutputPageAfterGetHeadLinksArray' hook, allowing extensions to
  70   modify the return value of OutputPage#getHeadLinksArray in order to add,
  71   remove or otherwise alter the elements to be output in the page <head>.
  72 * (T28934) The 'HistoryPageToolLinks' hook allows extensions to append
  73   additional links to the subtitle of a history page.
  74 * The 'GetLinkColours' hook now receives an additional $title parameter,
  75   the Title object of the page being parsed, on which the links will be shown.
  76 * (T194731) DifferenceEngine supports multiple slots. Added SlotDiffRenderer to
  77   render diffs between two Content objects, and DifferenceEngine::setRevisions()
  78   to render diffs between two custom (potentially multi-content) revisions.
  79   Added GetSlotDiffRenderer hook which works like GetDifferenceEngine for slots.
  80 * Added a temporary action=mcrundo to the web UI, as the normal undo logic
  81   can't yet handle MCR and deadlines are forcing is to put off fixing that.
  82   This action should be considered deprecated and should not be used directly.
  83 * Extensions overriding ContentHandler::getUndoContent() will need to be
  84   updated for the changed method signature.
  85

 104 ==== Removed and replaced external libraries ====
 105 * …
 106
 107 === Bug fixes in 1.32 ===
 108 * SpecialPage::execute() will now only call checkLoginSecurityLevel() if
 109   getLoginSecurityLevel() returns non-false.
 110
 111 === Action API changes in 1.32 ===
 112 * Added templated parameters.
 113   * A module can define a templated parameter like "{fruit}-quantity", where
 114     the actual parameters recognized correspond to the values of a multi-valued
 115     parameter. Then clients can make requests like
 116     "fruits=apples|bananas&apples-quantity=1&bananas-quantity=5".
 117   * action=paraminfo will return templated parameter definitions separately
 118     from normal parameters. All parameter definitions now include an "index"
 119     key to allow clients to maintain parameter ordering when merging normal and
 120     templated parameters.
 121 * It is now an error to submit too many values for a multi-valued parameter.
 122   This has generated a warning since MediaWiki 1.14.
 123 * Assertion failures from the 'assert' and 'assertuser' parameters will no
 124   longer use the action module's custom response format, for the few modules
 125   that use custom formatters that handle errors.
 126 * (T198935) User list preferences such as `email-blacklist` and similar
 127   extension preferences are no longer represented as arrays when returned by
 128   action=query&meta=userinfo&uiprop=options.
 129 * 'missingparam' errors will now use the prefixed parameter name in the code
 130   and error text, e.g. "noxxfoo" and "The 'xxfoo' parameter must be set" rather
 131   than "nofoo" and "The 'foo' parameter must be set".
 132 * action=query&prop=revisions now takes a 'rvslots' parameter to indicate the
 133   multi-content revision slots for which content should be returned. It also
 134   has a new rvprop, 'roles', to indicate which roles have slots. A deprecation
 135   warning will be issued if rvprop=content or rvprop=contentmodel are used
 136   without rvslots.
 137 * The rvcontentformat parameter to action=query&prop=revisions has been
 138   deprecated. Clients should be prepared to deal with the default format for
 139   relevant models.
 140 * Use of the deprecated parameters rvexpandtemplates, rvgeneratexml, rvparse,
 141   rvdiffto, rvdifftotext, rvdifftotextpst, rvcontentformat, or the deprecated
 142   rvprop=parsetree is forbidden with the new 'rvslots' parameter.
 143 * action=query&prop=deletedrevisions, action=query&list=allrevisions, and
 144   action=query&list=alldeletedrevisions are changed similarly to
 145   &prop=revisions (see the three previous items).
 146 * (T174032) action=compare now supports multi-content revisions.
 147   * It has a 'slots' parameter to select diffing of individual slots. The
 148     default behavior is to return one combined diff.
 149   * The 'fromtext', 'fromsection', 'fromcontentmodel', 'fromcontentformat',
 150     'totext', 'tosection', 'tocontentmodel', and 'tocontentformat' parameters
 151     are deprecated. Specify the new 'fromslots' and 'toslots' to identify which
 152     slots have text supplied and the corresponding templated parameters for
 153     each slot.
 154   * The behavior of 'fromsection' and 'tosection' of extracting one section's
 155     content is not being preserved. 'fromsection-{slot}' and 'tosection-{slot}'
 156     instead expand the given text as if for a section edit. This effectively
 157     declines T183823 in favor of T185723.
 158
 159 === Action API internal changes in 1.32 ===
 160 * Added 'ApiParseMakeOutputPage' hook.
 161 * Parameter names may no longer contain '{' or '}', as these are now used for
 162   templated parameters.
 163 * (T194950) Added 'ApiMaxLagInfo' hook.
 164 * Added 'ApiParseMakeOutputPage' hook.
 165 * The following methods now take a RevisionRecord rather than a Revision. No
 166   external callers are known.
 167   * ApiFeedContributions::feedItemAuthor()
 168   * ApiFeedContributions::feedItemDesc()
 169   * ApiQueryRevisionsBase::extractRevisionInfo()
 170
 171 === Languages updated in 1.32 ===
 172 MediaWiki supports over 350 languages. Many localisations are updated regularly.
 173 Below only new and removed languages are listed, as well as changes to languages
 174 because of Phabricator reports.
 175
 176 * (T193566) Added language support for Ambonese Malay (abs).
 177 * (T194047) Added language support for Shawiya, Latin script (shy-latn).
 178 * (T195940) Added language support for Batak Mandailing (btm).
 179 * (T137491) Added language support for Standard Moroccan Amazigh (zgh).
 180 * (T198132) Added language support for Manipuri (mni).
 181 * (T201276) Added language support for Western Armenian (hyw).

 183
 184 === Breaking changes in 1.32 ===

 202   * Revision::getRawUserText()
 203   * Revision::getRawComment()
 204 * window.gM() from mediawiki.jqueryMsg, deprecated in 1.23, was removed. Use

 206 * mw.util.escapeId(), deprecated in 1.30, was removed. Use
 207   mw.util.escapeIdForAttribute or mw.util.escapeIdForLink instead.
 208 * mw.util.updateTooltipAccessKeys(), deprecated in 1.24, was removed. Use
 209   jquery.accessKeyLabel instead.
 210 * The SqlDataUpdate class, deprecated in 1.28, has been removed.
 211 * The Html5Internal and Html5Depurate tidy driver classes were removed, along
 212   with the Balancer tidy implementation. Both implementations were experimental,
 213   and were replaced by RemexHtml.
 214 * (T179624) Job::insert() and ::batchInsert(), deprecated in 1.21, were both
 215   removed. Use JobQueueGroup::singleton()->push() instead.
 216 * The jquery.footHovzer module, for mediawiki.debug, was removed.
 217 * The es5-shim module, empty and deprecated since 1.29, was removed.
 218 * the dom-level2-shim module, empty and deprecated since 1.29, was removed.
 219 * the json module, empty and deprecated since 1.29, was removed.
 220 * The mediawiki.widgets.visibleByteLimit module alias, deprecated in 1.32, was

 222 * The jquery.farbtastic module, unused since 1.18, was removed.
 223 * The 'jquery.expandableField' module, unused since 1.22, was removed.
 224 * (T181318) The $wgStyleVersion setting and its appendage to various script and

 226 * The hooks 'PreferencesFormPreSave' and 'PreferencesGetLegend' may provide
 227   any HTMLForm object rather than PreferencesForm.
 228 * The non namespaced TimestampException class, deprecated in 1.29, was removed.
 229   Use Wikimedia\Timestamp\TimestampException instead.
 230 * The global functions codepointToUtf8, hexSequenceToUtf8, utf8ToHexSequence,
 231   utf8ToCodepoint, and escapeSingleString (deprecated in 1.25) were removed.
 232   The UtfNormal\Utils class from the utfnormal library should be used instead.
 233 * The deprecated UTF8_ and UNICODE_ constants were removed. The class constants
 234   from the UtfNormal\Constants class from the utfnormal library should be used
 235 * (T140807) The wgResourceLoaderLESSImportPaths configuration option was removed
 236   from ResourceLoader. Instead, use `@import` statements in LESS to import
 237   files directly from nearby directories within the same project.
 238 * (T140804) The wgResourceLoaderLESSVars configuration option, deprecated
 239   since 1.30, was removed. Instead, to expose variables from PHP to LESS, use
 240   the ResourceLoaderModule::getLessVars() method.
 241 * The protected methods PHPSessionHandler::returnSuccess() and returnFailure(),
 242   only needed for PHP5 compatibility, have been removed. It now uses the boolean
 243   values `true` and `false` respectively.
 244 * The $parserMemc global and wfGetParserCacheStorage(), deprecated since 1.30,
 245   were removed. Use the ParserCache class instead.
 246 * ScopedCallback (deprecated in 1.28) was removed. Use Wikimedia\ScopedCallback
 247   instead.
 248 * Support for ResourceLoaderModule::getModifiedTime() and getModifiedHash(),
 249   deprecated since 1.26, was removed. Use getDefinitionSummary() instead.
 250 * (T195256) Skins are recommended not to rely on JavaScript for the "mw-jump"
 251   and "jump-to-nav" accessibility links. To this end, the "jquery.mw-jump"
 252   is no longer loaded by default. The Vector and MonoBook skins have made a
 253   minor change to implement the toggle feature with CSS instead. To restore
 254   prior functionality, either explicitly load "jquery.mw-jump" in your skin
 255   or refer to T195256 for details on how to make the same change.
 256 * Hook 'EditPageBeforeEditChecks' was removed;
 257   use 'EditPageGetCheckboxesDefinition' instead.
 258 * Linker::getLinkColour() and DummyLinker::getLinkColour(), deprecated since
 259   1.28, were removed. LinkRenderer::getLinkClasses() should be used instead.
 260 * Wikimedia\Rdbms\LoadBalancer::getLaggedSlaveMode(), deprecated in 1.28, has
 261   been removed. Use Wikimedia\Rdbms\LoadBalancer::getLaggedReplicaMode()
 262   instead.
 263 * mw.widgets.CategoryMultiselectWidget now uses TagMultiselectWidget instead of
 264   CapsuleMultiselectWidget. The following methods may no longer be used:
 265   * setItemsFromData: Use setValue instead
 266   * getItemsData: Use getItems instead and get the data property
 267 * Two OutputPage methods, addMetadataLink() and getMetadataAttribute(), were
 268   removed.  Use addLink() instead.
 269 * Another two OutputPage methods, setPageTitleActionText() and
 270   getPageTitleActionText(), were removed.  They did nothing since 1.15 (almost
 271   ten years).  Use setHTMLTitle() directly.
 272 * All MagicWord static member variables have been removed.  Use appropriate
 273   hooks or MagicWordFactory methods instead.
 274 * MagicWord::clearCache() has been removed.  Instead, create a new
 275   MagicWordFactory, such as by calling
 276   resetServiceForTesting( 'MagicWordFactory' ) on a MediaWikiServices.
 277 * mw.util.init() has been removed. This function is not needed anymore and was
 278   a no-op function since 1.30.
 279 * SpecialPageFactory::resetList() is a no-op.  Call overrideMwServices()
 280   instead.
 281 * MediaWiki no longer supports a StartProfiler.php file.
 282   Define $wgProfiler via LocalSettings.php instead.
 283
 284 === Deprecations in 1.32 ===
 285 * HTMLForm::setSubmitProgressive() is deprecated. No need to call it. Submit
 286   button is already marked as progressive.
 287 * Skin::setupSkinUserCss() is deprecated. Adding of modules to load
 288   has been centralised to Skin::getDefaultModules(), which is now capable
 289   of queueing style modules as well.
 290 * OutputPage::addModuleScripts() and ParserOutput::addModuleScripts are
 291   deprecated. Use addModules() instead.
 292 * Overriding SearchEngine::{searchText,searchTitle,searchArchiveTitle}
 293   in extending classes is deprecated.  Extend related doSearch* methods
 294   instead.
 295 * CollationFa has been removed completely as it's not needed anymore
 296 * The following 'mediawiki.api' plugin modules were merged into mediawiki.api
 297   and deprecated: mediawiki.api.category, mediawiki.api.edit,
 298   mediawiki.api.login, mediawiki.api.options, mediawiki.api.parse,
 299   mediawiki.api.upload, mediawiki.api.user, mediawiki.api.watch,
 300   mediawiki.api.messages, and mediawiki.api.rollback.
 301 * ApiBase::truncateArray() is deprecated. No replacement, as nothing is known
 302   to use it.
 303 * WatchAction::getUnwatchToken is deprecated. Use WatchAction::getWatchToken
 304   with the 'unwatch' action parameter instead.
 305 * IcuCollation::getICUVersion() is deprecated, as you can just use the PHP
 306   constant INTL_ICU_VERSION directly in all versions that MediaWiki supports.
 307 * Parser::fetchFile() is deprecated. Use ::fetchFileAndTitle() instead.
 308 * The ApiQueryContributions class has been renamed to ApiQueryUserContribs.
 309 * The XMPInfo, XMPReader, and XMPValidate classes have been deprecated in favor
 310   of the namespaced classes provided by the wikimedia/xmp-reader library.
 311 * SearchResultSet::{next,rewind} are deprecated. Calling code should
 312   use foreach on the SearchResultSet, or the extractResults method. Extending
 313   code should override extractResults.
 314 * Instantiating SearchResultSet directly is deprecated. SearchEngine
 315   implementations must subclass SearchResultSet for their purposes.
 316 * SearchResult::setExtensionData argument has been changed from accepting an
 317   array to accepting a Closure that returns the array when called.
 318 * Class CryptRand, everything in MWCryptRand except generateHex() and function
 319   MediaWikiServices::getCryptRand() are deprecated, use random_bytes() to
 320   generate cryptographically secure random byte sequences.
 321 * Parser::getConverterLanguage() is deprecated.  Use ::getTargetLanguage()
 322   instead.
 323 * Language::markNoConversion() is deprecated.  It confused readers because
 324   it had unexpected behavior (only marking text if it looked like a URL)
 325   and was only used in a single place in the code.  Use
 326   LanguageConverter::markNoConversion() instead.
 327 * (T197492) Language::truncate() was soft deprecated in 1.31 and is
 328   hard deprecated in this release.  It has been split into two similar
 329   methods, Language::truncateForVisual() and Language::truncateForDatabase(),
 330   which measure length in characters and bytes, respectively.  Use
 331   Language::truncateForVisual() when possible to provide equity to users
 332   of multibyte scripts.
 333 * (T176526) EditPage::getContextTitle() falling back to $wgTitle when the
 334   context title is unset is now deprecated; anything creating an EditPage
 335   instance should set the context title via ::setContextTitle().
 336 * The 'jquery.hidpi' module (polyfill for IMG srcset) is deprecated.
 337 * ResourceLoaderStartUpModule::getStartupModules() and ::getLegacyModules()
 338   are deprecated. These concepts are obsolete and have no replacement.
 339 * String type for $lang of DifferenceEngine::setTextLanguage is deprecated.
 340 * The following methods of OutputPage are now deprecated in favour
 341   of using showFatalError directly: OutputPage::showFileDeleteError()
 342   OutputPage::showFileNotFoundError(), OutputPage::showFileRenameError()
 343   OutputPage::showFileCopyError() and OutputPage::showUnexpectedValueError().
 344 * The Replacer, DoubleReplacer, HashtableReplacer, and RegexlikeReplacer
 345   classes are now deprecated. Use a Closure instead.
 346 * (T194263) ContentHandler::makeParserOptions() is deprecated. Use
 347   WikiPage::makeParserOptions() or ParserOptions::newCanonical() instead.
 348 * (T100681) Use of the Parsoid v1 API with the VirtualRESTService, deprecated in
 349   MediaWiki 1.26,  is now hard-deprecated. All known clients were converted to
 350   the Parsoid v3 API in May 2015.
 351 * $input is deprecated in hook 'LogEventsListGetExtraInputs'. Use
 352   $formDescriptor instead.
 353 * SearchEngine::transformSearchTerm( $term ) should no longer be called prior
 354   to running searchText. This method was mainly implemented to support the
 355   'prefix' URI param in SpecialSearch, but there are no reasons to expose this
 356   logic as it should be handled internally by SearchEngine implementations
 357   supporting this feature. SearchEngine implementations should no longer
 358   override this methods.
 359 * SearchEngine::replacePrefixes( $query ) should no longer be called prior
 360   to running searchText/searchTitle.
 361 * (T199657) Messages for $wgFilterLogTypes labels should be no longer be in the
 362   'log-show-hide-[type]' format. Instead use 'logeventslist-[type]-log'.
 363 * Global functions  wfArrayFilter() and wfArrayFilterByKey() are deprecated.
 364   use array_filter() directly.
 365 * The $wgShowSQLErrors global is deprecated and nonfunctional.
 366   Set $wgShowExceptionDetails and/or $wgShowHostnames instead.
 367 * The $wgShowDBErrorBacktrace global is deprecated and nonfunctional.
 368   Set $wgShowExceptionDetails instead.
 369 * Public access to the DifferenceEngine properties mOldid, mNewid, mOldRev,
 370   mNewRev, mOldPage, mNewPage, mOldContent, mNewContent, mRevisionsLoaded,
 371   mTextLoaded and mCacheHit is deprecated. Use getOldid() / getNewid() /
 372   getOldRevision() / getNewRevision() for the first four (note that the
 373   revision ones return a RevisionRecord, not a Revision), do your own lookup
 374   for page/content.
 375 * The $wgExternalDiffEngine value 'wikidiff2' is deprecated. To use wikidiff2
 376   just enable the PHP extension, and it will be autodetected.
 377 * (T194731) DifferenceEngine properties mOldContent and mNewContent and methods
 378   setContent(), generateContentDiffBody(), generateTextDiffBody() and textDiff()
 379   are deprecated. To interact with a single slot, use a SlotDiffRenderer (and
 380   subclass it to customize diff rendering); to diff custom (e.g. unsaved)
 381   content, use setRevisions(). Subclassing DifferenceEngine should only be done
 382   to customize page-level diff properties (such as the navigation header).
 383 * The wfUseMW function, soft-deprecated in 1.26, is now hard deprecated.
 384 * All MagicWord static methods are now deprecated.  Use the MagicWordFactory
 385   methods instead.
 386 * PasswordFactory::init is deprecated. To get a password factory with the
 387   standard configuration, use MediaWikiServices::getPasswordFactory.
 388 * $wgContLang is deprecated, use MediaWikiServices::getContentLanguage()
 389   instead.
 390 * $wgParser is deprecated, use MediaWikiServices::getParser() instead.
 391 * wfGetMainCache() is deprecated, use ObjectCache::getLocalClusterInstance()
 392   instead.
 393 * wfGetCache() is deprecated, use ObjectCache::getInstance() instead.
 394 * All SpecialPageFactory static methods are deprecated. Instead, call the
 395   methods on a SpecialPageFactory instance, which may be obtained from
 396   MediaWikiServices.
 397 * mw.user.stickyRandomId was renamed to the more explicit
 398   mw.user.getPageviewToken to better capture its function.
 399 * Passing Revision objects to ContentHandler::getUndoContent() is deprecated,
 400   Content object should be passed instead.
 401 * (T197179) Parameters 'notice', 'notice-messages', 'notice-message',
 402   previously used by OOUI HTMLForm fields, are now deprecated. Use
 403   'help', 'help-message', 'help-messages' instead.
 404 * (T197179) HTMLFormField::getNotices() is now deprecated.
 405 * The jquery.localize module is now deprecated. Use jquery.i18n instead.
 406
 407 === Other changes in 1.32 ===
 408 * (T198811) The following tables have had their UNIQUE indexes turned into
 409   proper PRIMARY KEYs for increased maintainability: interwiki, page_props,
 410   protected_titles and site_identifiers.
 411 * OOUI HTMLForm will now display help text inline after the input field,
 412   rather than in a popup. Previous behavior can be restored by using
 413   `'help-inline' => false`.
 414 * …

 416 == Compatibility ==
 417 MediaWiki 1.32 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 418 supported, it is generally advised to use PHP 7.0.0 or later for long term
 419 support.
 420
 421 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 422 but support for them is somewhat less mature. There is experimental support for
 423 Oracle and Microsoft SQL Server.
 424
 425 The supported versions are:
 426
 427 * MySQL 5.5.8 or later
 428 * PostgreSQL 9.2 or later
 429 * SQLite 3.3.7 or later
 430 * Oracle 9.0.1 or later
 431 * Microsoft SQL Server 2005 (9.00.1399)
 432
 433 == Upgrading ==
 434 1.32 has several database changes since 1.31, and will not work without schema
 435 updates. Note that due to changes to some very large tables like the revision
 436 table, the schema update may take quite long (minutes on a medium sized site,
 437 many hours on a large site).
 438
 439 Don't forget to always back up your database before upgrading!
 440
 441 See the file UPGRADE for more detailed upgrade instructions, including
 442 important information when upgrading from versions prior to 1.11.
