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
  44 === New features in 1.32 ===
  45 * (T112474) Generalized the ResourceLoader mechanism for overriding modules
  46   using a particular page during edit previews.
  47 * (T12331) You can now log page creation events by setting $wgPageCreationLog
  48   to true.
  49 * Added 'ApiParseMakeOutputPage' hook.
  50 * (T174313) Added checkbox on Special:ListUsers to display only users in
  51   temporary user groups.
  52 * (T152462) A cookie can now be set when an IP user is blocked to track that
  53   user if they move to a new IP address. This is disabled by default.
  54 * (T194950) Added 'ApiMaxLagInfo' hook.
  55 * SpecialPage::checkLoginSecurityLevel() will now preserve POST data when
  56   reauthenticating.
  57 * FormSpecialPage::execute() will now call checkLoginSecurityLevel() if
  58   getLoginSecurityLevel() returns non-false.
  59 * The 'ImageBeforeProduceHTML' hook is now passed three new parameters, $parser,
  60   &$query and &$widthOption, allowing extensions even finer control over the
  61   resulting HTML code.
  62 * Added new 'ArticleShowPatrolFooter' hook, which allows extensions to determine
  63   if the [mark as patrolled] link should be shown at the footer of patrollable
  64   pages.
  65 * The array of hidden options ($opts) passed to the 'SpecialSearchPowerBox' hook
  66   is now passed by reference, allowing extensions to modify or even unset it.
  67 * Added new 'OutputPageAfterGetHeadLinksArray' hook, allowing extensions to
  68   modify the return value of OutputPage#getHeadLinksArray in order to add,
  69   remove or otherwise alter the elements to be output in the page <head>.
  70 * (T28934) The 'HistoryPageToolLinks' hook allows extensions to append
  71   additional links to the subtitle of a history page.
  72 * The 'GetLinkColours' hook now receives an additional $title parameter,
  73   the Title object of the page being parsed, on which the links will be shown.
  74 * (T194731) DifferenceEngine supports multiple slots. Added SlotDiffRenderer to
  75   render diffs between two Content objects, and DifferenceEngine::setRevisions()
  76   to render diffs between two custom (potentially multi-content) revisions.
  77   Added GetSlotDiffRenderer hook which works like GetDifferenceEngine for slots.

  99
 100 === Bug fixes in 1.32 ===
 101 * SpecialPage::execute() will now only call checkLoginSecurityLevel() if
 102   getLoginSecurityLevel() returns non-false.
 103
 104 === Action API changes in 1.32 ===
 105 * Added templated parameters.
 106   * A module can define a templated parameter like "{fruit}-quantity", where
 107     the actual parameters recognized correspond to the values of a multi-valued
 108     parameter. Then clients can make requests like
 109     "fruits=apples|bananas&apples-quantity=1&bananas-quantity=5".
 110   * action=paraminfo will return templated parameter definitions separately
 111     from normal parameters. All parameter definitions now include an "index"
 112     key to allow clients to maintain parameter ordering when merging normal and
 113     templated parameters.
 114 * It is now an error to submit too many values for a multi-valued parameter.
 115   This has generated a warning since MediaWiki 1.14.
 116 * Assertion failures from the 'assert' and 'assertuser' parameters will no
 117   longer use the action module's custom response format, for the few modules
 118   that use custom formatters that handle errors.
 119 * (T198935) User list preferences such as `email-blacklist` and similar
 120   extension preferences are no longer represented as arrays when returned by
 121   action=query&meta=userinfo&uiprop=options.
 122 * 'missingparam' errors will now use the prefixed parameter name in the code
 123   and error text, e.g. "noxxfoo" and "The 'xxfoo' parameter must be set" rather
 124   than "nofoo" and "The 'foo' parameter must be set".
 125 * action=query&prop=revisions now takes a 'rvslots' parameter to indicate the
 126   multi-content revision slots for which content should be returned. It also
 127   has a new rvprop, 'roles', to indicate which roles have slots. A deprecation
 128   warning will be issued if rvprop=content or rvprop=contentmodel are used
 129   without rvslots.
 130 * The rvcontentformat parameter to action=query&prop=revisions has been
 131   deprecated. Clients should be prepared to deal with the default format for
 132   relevant models.
 133 * Use of the deprecated parameters rvexpandtemplates, rvgeneratexml, rvparse,
 134   rvdiffto, rvdifftotext, rvdifftotextpst, rvcontentformat, or the deprecated
 135   rvprop=parsetree is forbidden with the new 'rvslots' parameter.
 136 * action=query&prop=deletedrevisions, action=query&list=allrevisions, and
 137   action=query&list=alldeletedrevisions are changed similarly to
 138   &prop=revisions (see the three previous items).
 139 * (T174032) action=compare now supports multi-content revisions.
 140   * It has a 'slots' parameter to select diffing of individual slots. The
 141     default behavior is to return one combined diff.
 142   * The 'fromtext', 'fromsection', 'fromcontentmodel', 'fromcontentformat',
 143     'totext', 'tosection', 'tocontentmodel', and 'tocontentformat' parameters
 144     are deprecated. Specify the new 'fromslots' and 'toslots' to identify which
 145     slots have text supplied and the corresponding templated parameters for
 146     each slot.
 147   * The behavior of 'fromsection' and 'tosection' of extracting one section's
 148     content is not being preserved. 'fromsection-{slot}' and 'tosection-{slot}'
 149     instead expand the given text as if for a section edit. This effectively
 150     declines T183823 in favor of T185723.
 151
 152 === Action API internal changes in 1.32 ===
 153 * Added 'ApiParseMakeOutputPage' hook.
 154 * Parameter names may no longer contain '{' or '}', as these are now used for
 155   templated parameters.
 156 * (T194950) Added 'ApiMaxLagInfo' hook.
 157 * Added 'ApiParseMakeOutputPage' hook.
 158 * The following methods now take a RevisionRecord rather than a Revision. No
 159   external callers are known.
 160   * ApiFeedContributions::feedItemAuthor()
 161   * ApiFeedContributions::feedItemDesc()
 162   * ApiQueryRevisionsBase::extractRevisionInfo()
 163
 164 === Languages updated in 1.32 ===
 165 MediaWiki supports over 350 languages. Many localisations are updated regularly.
 166 Below only new and removed languages are listed, as well as changes to languages
 167 because of Phabricator reports.
 168
 169 * (T193566) Added language support for Ambonese Malay (abs).
 170 * (T194047) Added language support for Shawiya, Latin script (shy-latn).
 171 * (T195940) Added language support for Batak Mandailing (btm).
 172 * (T137491) Added language support for Standard Moroccan Amazigh (zgh).

 176
 177 === Breaking changes in 1.32 ===

 195   * Revision::getRawUserText()
 196   * Revision::getRawComment()
 197 * window.gM() from mediawiki.jqueryMsg, deprecated in 1.23, was removed. Use

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

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

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

 393 === Other changes in 1.32 ===
 394 * (T198811) The following tables have had their UNIQUE indexes turned into
 395   proper PRIMARY KEYs for increased maintainability: interwiki, page_props,
 396   protected_titles and site_identifiers.
 397 * OOUI HTMLForm will now display help text inline after the input field,
 398   rather than in a popup. Previous behavior can be restored by using
 399   `'help-inline' => false`.

 402 == Compatibility ==
 403 MediaWiki 1.32 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 404 supported, it is generally advised to use PHP 7.0.0 or later for long term
 405 support.
 406
 407 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 408 but support for them is somewhat less mature. There is experimental support for
 409 Oracle and Microsoft SQL Server.
 410
 411 The supported versions are:
 412
 413 * MySQL 5.5.8 or later
 414 * PostgreSQL 9.2 or later
 415 * SQLite 3.3.7 or later
 416 * Oracle 9.0.1 or later
 417 * Microsoft SQL Server 2005 (9.00.1399)
 418
 419 == Upgrading ==
 420 1.32 has several database changes since 1.31, and will not work without schema
 421 updates. Note that due to changes to some very large tables like the revision
 422 table, the schema update may take quite long (minutes on a medium sized site,
 423 many hours on a large site).
 424
 425 Don't forget to always back up your database before upgrading!
 426
 427 See the file UPGRADE for more detailed upgrade instructions, including
 428 important information when upgrading from versions prior to 1.11.
