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

  92
  93 === Bug fixes in 1.32 ===
  94 * SpecialPage::execute() will now only call checkLoginSecurityLevel() if
  95   getLoginSecurityLevel() returns non-false.
  96
  97 === Action API changes in 1.32 ===
  98 * Added templated parameters.
  99   * A module can define a templated parameter like "{fruit}-quantity", where
 100     the actual parameters recognized correspond to the values of a multi-valued
 101     parameter. Then clients can make requests like
 102     "fruits=apples|bananas&apples-quantity=1&bananas-quantity=5".
 103   * action=paraminfo will return templated parameter definitions separately
 104     from normal parameters. All parameter definitions now include an "index"
 105     key to allow clients to maintain parameter ordering when merging normal and
 106     templated parameters.
 107 * It is now an error to submit too many values for a multi-valued parameter.
 108   This has generated a warning since MediaWiki 1.14.
 109 * Assertion failures from the 'assert' and 'assertuser' parameters will no
 110   longer use the action module's custom response format, for the few modules
 111   that use custom formatters that handle errors.
 112 * (T198935) User list preferences such as `email-blacklist` and similar
 113   extension preferences are no longer represented as arrays when returned by
 114   action=query&meta=userinfo&uiprop=options.
 115 * 'missingparam' errors will now use the prefixed parameter name in the code
 116   and error text, e.g. "noxxfoo" and "The 'xxfoo' parameter must be set" rather
 117   than "nofoo" and "The 'foo' parameter must be set".
 118 * action=query&prop=revisions now takes a 'rvslots' parameter to indicate the
 119   multi-content revision slots for which content should be returned. It also
 120   has a new rvprop, 'roles', to indicate which roles have slots. A deprecation
 121   warning will be issued if rvprop=content or rvprop=contentmodel are used
 122   without rvslots.
 123 * The rvcontentformat parameter to action=query&prop=revisions has been
 124   deprecated. Clients should be prepared to deal with the default format for
 125   relevant models.
 126 * Use of the deprecated parameters rvexpandtemplates, rvgeneratexml, rvparse,
 127   rvdiffto, rvdifftotext, rvdifftotextpst, rvcontentformat, or the deprecated
 128   rvprop=parsetree is forbidden with the new 'rvslots' parameter.
 129 * action=query&prop=deletedrevisions, action=query&list=allrevisions, and
 130   action=query&list=alldeletedrevisions are changed similarly to
 131   &prop=revisions (see the three previous items).
 132
 133 === Action API internal changes in 1.32 ===
 134 * Added 'ApiParseMakeOutputPage' hook.
 135 * Parameter names may no longer contain '{' or '}', as these are now used for
 136   templated parameters.
 137 * (T194950) Added 'ApiMaxLagInfo' hook.
 138 * Added 'ApiParseMakeOutputPage' hook.
 139 * The following methods now take a RevisionRecord rather than a Revision. No
 140   external callers are known.
 141   * ApiFeedContributions::feedItemAuthor()
 142   * ApiFeedContributions::feedItemDesc()
 143   * ApiQueryRevisionsBase::extractRevisionInfo()
 144
 145 === Languages updated in 1.32 ===
 146 MediaWiki supports over 350 languages. Many localisations are updated regularly.
 147 Below only new and removed languages are listed, as well as changes to languages
 148 because of Phabricator reports.
 149
 150 * (T193566) Added language support for Ambonese Malay (abs).
 151 * (T194047) Added language support for Shawiya, Latin script (shy-latn).
 152 * (T195940) Added language support for Batak Mandailing (btm).

 157
 158 === Breaking changes in 1.32 ===

 186   with the Balancer tidy implementation. Both implementations were experimental,
 187   and were replaced by RemexHtml.
 188 * (T179624) Job::insert() and ::batchInsert(), deprecated in 1.21, were both
 189   removed. Use JobQueueGroup::singleton()->push() instead.
 190 * The jquery.footHovzer module, for mediawiki.debug, was removed.

 200 * The hooks 'PreferencesFormPreSave' and 'PreferencesGetLegend' may provide
 201   any HTMLForm object rather than PreferencesForm.
 202 * The non namespaced TimestampException class, deprecated in 1.29, was removed.
 203   Use Wikimedia\Timestamp\TimestampException instead.
 204 * The global functions codepointToUtf8, hexSequenceToUtf8, utf8ToHexSequence,
 205   utf8ToCodepoint, and escapeSingleString (deprecated in 1.25) were removed.
 206   The UtfNormal\Utils class from the utfnormal library should be used instead.
 207 * The deprecated UTF8_ and UNICODE_ constants were removed. The class constants
 208   from the UtfNormal\Constants class from the utfnormal library should be used
 209 * (T140807) The wgResourceLoaderLESSImportPaths configuration option was removed
 210   from ResourceLoader. Instead, use `@import` statements in LESS to import
 211   files directly from nearby directories within the same project.
 212 * (T140804) The wgResourceLoaderLESSVars configuration option, deprecated
 213   since 1.30, was removed. Instead, to expose variables from PHP to LESS, use
 214   the ResourceLoaderModule::getLessVars() method.
 215 * The protected methods PHPSessionHandler::returnSuccess() and returnFailure(),
 216   only needed for PHP5 compatibility, have been removed. It now uses the boolean
 217   values `true` and `false` respectively.
 218 * The $parserMemc global and wfGetParserCacheStorage(), deprecated since 1.30,

 221   instead.
 222 * Support for ResourceLoaderModule::getModifiedTime() and getModifiedHash(),
 223   deprecated since 1.26, was removed. Use getDefinitionSummary() instead.
 224 * (T195256) Skins are recommended not to rely on JavaScript for the "mw-jump"
 225   and "jump-to-nav" accessibility links. To this end, the "jquery.mw-jump"
 226   is no longer loaded by default. The Vector and MonoBook skins have made a
 227   minor change to implement the toggle feature with CSS instead. To restore
 228   prior functionality, either explicitly load "jquery.mw-jump" in your skin
 229   or refer to T195256 for details on how to make the same change.
 230 * Hook 'EditPageBeforeEditChecks' was removed;
 231   use 'EditPageGetCheckboxesDefinition' instead.
 232 * Linker::getLinkColour() and DummyLinker::getLinkColour(), deprecated since
 233   1.28, were removed. LinkRenderer::getLinkClasses() should be used instead.
 234 * Wikimedia\Rdbms\LoadBalancer::getLaggedSlaveMode(), deprecated in 1.28, has
 235   been removed. Use Wikimedia\Rdbms\LoadBalancer::getLaggedReplicaMode()
 236   instead.
 237 * mw.widgets.CategoryMultiselectWidget now uses TagMultiselectWidget instead of
 238   CapsuleMultiselectWidget. The following methods may no longer be used:
 239   * setItemsFromData: Use setValue instead
 240   * getItemsData: Use getItems instead and get the data property
 241 * Two OutputPage methods, addMetadataLink() and getMetadataAttribute(), were
 242   removed.  Use addLink() instead.
 243 * Another two OutputPage methods, setPageTitleActionText() and
 244   getPageTitleActionText(), were removed.  They did nothing since 1.15 (almost
 245   ten years).  Use setHTMLTitle() directly.
 246 * All MagicWord static member variables have been removed.  Use appropriate
 247   hooks or MagicWordFactory methods instead.
 248 * MagicWord::clearCache() has been removed.  Instead, create a new
 249   MagicWordFactory, such as by calling
 250   resetServiceForTesting( 'MagicWordFactory' ) on a MediaWikiServices.
 251 * mw.util.init() has been removed. This function is not needed anymore and was
 252   a no-op function since 1.30.
 253 * SpecialPageFactory::resetList() is a no-op.  Call overrideMwServices()
 254   instead.
 255
 256 === Deprecations in 1.32 ===
 257 * Use of a StartProfiler.php file is deprecated in favour of placing
 258   configuration in LocalSettings.php.
 259 * HTMLForm::setSubmitProgressive() is deprecated. No need to call it. Submit
 260   button is already marked as progressive.
 261 * Skin::setupSkinUserCss() is deprecated. Adding of modules to load
 262   has been centralised to Skin::getDefaultModules(), which is now capable
 263   of queueing style modules as well.
 264 * OutputPage::addModuleScripts() and ParserOutput::addModuleScripts are
 265   deprecated. Use addModules() instead.
 266 * Overriding SearchEngine::{searchText,searchTitle,searchArchiveTitle}
 267   in extending classes is deprecated.  Extend related doSearch* methods
 268   instead.
 269 * CollationFa has been removed completely as it's not needed anymore
 270 * The following 'mediawiki.api' plugin modules were merged into mediawiki.api
 271   and deprecated: mediawiki.api.category, mediawiki.api.edit,
 272   mediawiki.api.login, mediawiki.api.options, mediawiki.api.parse,
 273   mediawiki.api.upload, mediawiki.api.user, mediawiki.api.watch,
 274   mediawiki.api.messages, and mediawiki.api.rollback.
 275 * ApiBase::truncateArray() is deprecated. No replacement, as nothing is known
 276   to use it.
 277 * WatchAction::getUnwatchToken is deprecated. Use WatchAction::getWatchToken
 278   with the 'unwatch' action parameter instead.
 279 * IcuCollation::getICUVersion() is deprecated, as you can just use the PHP
 280   constant INTL_ICU_VERSION directly in all versions that MediaWiki supports.
 281 * Parser::fetchFile() is deprecated. Use ::fetchFileAndTitle() instead.
 282 * The ApiQueryContributions class has been renamed to ApiQueryUserContribs.
 283 * The XMPInfo, XMPReader, and XMPValidate classes have been deprecated in favor
 284   of the namespaced classes provided by the wikimedia/xmp-reader library.
 285 * SearchResultSet::{next,rewind} are deprecated. Calling code should
 286   use foreach on the SearchResultSet, or the extractResults method. Extending
 287   code should override extractResults.
 288 * Instantiating SearchResultSet directly is deprecated. SearchEngine
 289   implementations must subclass SearchResultSet for their purposes.
 290 * SearchResult::setExtensionData argument has been changed from accepting an
 291   array to accepting a Closure that returns the array when called.
 292 * Class CryptRand, everything in MWCryptRand except generateHex() and function
 293   MediaWikiServices::getCryptRand() are deprecated, use random_bytes() to
 294   generate cryptographically secure random byte sequences.
 295 * Parser::getConverterLanguage() is deprecated.  Use ::getTargetLanguage()
 296   instead.
 297 * Language::markNoConversion() is deprecated.  It confused readers because
 298   it had unexpected behavior (only marking text if it looked like a URL)
 299   and was only used in a single place in the code.  Use
 300   LanguageConverter::markNoConversion() instead.
 301 * (T197492) Language::truncate() was soft deprecated in 1.31 and is
 302   hard deprecated in this release.  It has been split into two similar
 303   methods, Language::truncateForVisual() and Language::truncateForDatabase(),
 304   which measure length in characters and bytes, respectively.  Use
 305   Language::truncateForVisual() when possible to provide equity to users
 306   of multibyte scripts.
 307 * (T176526) EditPage::getContextTitle() falling back to $wgTitle when the
 308   context title is unset is now deprecated; anything creating an EditPage
 309   instance should set the context title via ::setContextTitle().
 310 * The 'jquery.hidpi' module (polyfill for IMG srcset) is deprecated.
 311 * ResourceLoaderStartUpModule::getStartupModules() and ::getLegacyModules()
 312   are deprecated. These concepts are obsolete and have no replacement.
 313 * String type for $lang of DifferenceEngine::setTextLanguage is deprecated.
 314 * The following methods of OutputPage are now deprecated in favour
 315   of using showFatalError directly: OutputPage::showFileDeleteError()
 316   OutputPage::showFileNotFoundError(), OutputPage::showFileRenameError()
 317   OutputPage::showFileCopyError() and OutputPage::showUnexpectedValueError().
 318 * The Replacer, DoubleReplacer, HashtableReplacer, and RegexlikeReplacer
 319   classes are now deprecated. Use a Closure instead.
 320 * (T194263) ContentHandler::makeParserOptions() is deprecated. Use
 321   WikiPage::makeParserOptions() or ParserOptions::newCanonical() instead.
 322 * (T100681) Use of the Parsoid v1 API with the VirtualRESTService, deprecated in
 323   MediaWiki 1.26,  is now hard-deprecated. All known clients were converted to
 324   the Parsoid v3 API in May 2015.
 325 * $input is deprecated in hook 'LogEventsListGetExtraInputs'. Use
 326   $formDescriptor instead.
 327 * SearchEngine::transformSearchTerm( $term ) should no longer be called prior
 328   to running searchText. This method was mainly implemented to support the
 329   'prefix' URI param in SpecialSearch, but there are no reasons to expose this
 330   logic as it should be handled internally by SearchEngine implementations
 331   supporting this feature. SearchEngine implementations should no longer
 332   override this methods.
 333 * SearchEngine::replacePrefixes( $query ) should no longer be called prior
 334   to running searchText/searchTitle.
 335 * (T199657) Messages for $wgFilterLogTypes labels should be no longer be in the
 336   'log-show-hide-[type]' format. Instead use 'logeventslist-[type]-log'.
 337 * Global functions  wfArrayFilter() and wfArrayFilterByKey() are deprecated.
 338   use array_filter() directly.
 339 * The $wgShowSQLErrors global is deprecated and nonfunctional.
 340   Set $wgShowExceptionDetails and/or $wgShowHostnames instead.
 341 * The $wgShowDBErrorBacktrace global is deprecated and nonfunctional.
 342   Set $wgShowExceptionDetails instead.
 343 * Public access to the DifferenceEngine properties mOldid, mNewid, mOldPage,
 344   mNewPage, mOldContent, mNewContent, mRevisionsLoaded, mTextLoaded and
 345   mCacheHit is deprecated. Use getOldid() / getNewid() for the first two,
 346   do your own lookup for page/content. mNewRev / mOldRev remains public.
 347 * The $wgExternalDiffEngine value 'wikidiff2' is deprecated. To use wikidiff2
 348   just enable the PHP extension, and it will be autodetected.
 349 * The wfUseMW function, soft-deprecated in 1.26, is now hard deprecated.
 350 * All MagicWord static methods are now deprecated.  Use the MagicWordFactory
 351   methods instead.
 352 * PasswordFactory::init is deprecated. To get a password factory with the
 353   standard configuration, use MediaWikiServices::getPasswordFactory.
 354 * $wgContLang is deprecated, use MediaWikiServices::getContentLanguage()
 355   instead.
 356 * $wgParser is deprecated, use MediaWikiServices::getParser() instead.
 357 * wfGetMainCache() is deprecated, use ObjectCache::getLocalClusterInstance()
 358   instead.
 359 * wfGetCache() is deprecated, use ObjectCache::getInstance() instead.
 360 * All SpecialPageFactory static methods are deprecated. Instead, call the
 361   methods on a SpecialPageFactory instance, which may be obtained from
 362   MediaWikiServices.
 363
 364 === Other changes in 1.32 ===
 365 * (T198811) The following tables have had their UNIQUE indexes turned into
 366   proper PRIMARY KEYs for increased maintainability: interwiki, page_props,
 367   protected_titles and site_identifiers.
 368 * OOUI HTMLForm will now display help text inline after the input field,
 369   rather than in a popup. Previous behavior can be restored by using
 370   `'help-inline' => false`.
 371 * …
 372
 373 == Compatibility ==
 374 MediaWiki 1.32 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 375 supported, it is generally advised to use PHP 7.0.0 or later for long term
 376 support.
 377
 378 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 379 but support for them is somewhat less mature. There is experimental support for
 380 Oracle and Microsoft SQL Server.
 381
 382 The supported versions are:
 383
 384 * MySQL 5.5.8 or later
 385 * PostgreSQL 9.2 or later
 386 * SQLite 3.3.7 or later
 387 * Oracle 9.0.1 or later
 388 * Microsoft SQL Server 2005 (9.00.1399)
 389
 390 == Upgrading ==
 391 1.32 has several database changes since 1.31, and will not work without schema
 392 updates. Note that due to changes to some very large tables like the revision
 393 table, the schema update may take quite long (minutes on a medium sized site,
 394 many hours on a large site).
 395
 396 Don't forget to always back up your database before upgrading!
 397
 398 See the file UPGRADE for more detailed upgrade instructions, including
 399 important information when upgrading from versions prior to 1.11.
