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.
  71
  72 === External library changes in 1.32 ===

  88 * …
  89
  90 === Bug fixes in 1.32 ===
  91 * SpecialPage::execute() will now only call checkLoginSecurityLevel() if
  92   getLoginSecurityLevel() returns non-false.
  93
  94 === Action API changes in 1.32 ===
  95 * Added templated parameters.
  96   * A module can define a templated parameter like "{fruit}-quantity", where
  97     the actual parameters recognized correspond to the values of a multi-valued
  98     parameter. Then clients can make requests like
  99     "fruits=apples|bananas&apples-quantity=1&bananas-quantity=5".
 100   * action=paraminfo will return templated parameter definitions separately
 101     from normal parameters. All parameter definitions now include an "index"
 102     key to allow clients to maintain parameter ordering when merging normal and
 103     templated parameters.
 104 * It is now an error to submit too many values for a multi-valued parameter.
 105   This has generated a warning since MediaWiki 1.14.
 106 * Assertion failures from the 'assert' and 'assertuser' parameters will no
 107   longer use the action module's custom response format, for the few modules
 108   that use custom formatters that handle errors.
 109 * (T198935) User list preferences such as `email-blacklist` and similar
 110   extension preferences are no longer represented as arrays when returned by
 111   action=query&meta=userinfo&uiprop=options.
 112 * 'missingparam' errors will now use the prefixed parameter name in the code
 113   and error text, e.g. "noxxfoo" and "The 'xxfoo' parameter must be set" rather
 114   than "nofoo" and "The 'foo' parameter must be set".
 115 * action=query&prop=revisions now takes a 'rvslots' parameter to indicate the
 116   multi-content revision slots for which content should be returned. It also
 117   has a new rvprop, 'roles', to indicate which roles have slots. A deprecation
 118   warning will be issued if rvprop=content or rvprop=contentmodel are used
 119   without rvslots.
 120 * The rvcontentformat parameter to action=query&prop=revisions has been
 121   deprecated. Clients should be prepared to deal with the default format for
 122   relevant models.
 123 * Use of the deprecated parameters rvexpandtemplates, rvgeneratexml, rvparse,
 124   rvdiffto, rvdifftotext, rvdifftotextpst, rvcontentformat, or the deprecated
 125   rvprop=parsetree is forbidden with the new 'rvslots' parameter.
 126 * action=query&prop=deletedrevisions, action=query&list=allrevisions, and
 127   action=query&list=alldeletedrevisions are changed similarly to
 128   &prop=revisions (see the three previous items).
 129
 130 === Action API internal changes in 1.32 ===
 131 * Added 'ApiParseMakeOutputPage' hook.
 132 * Parameter names may no longer contain '{' or '}', as these are now used for
 133   templated parameters.
 134 * (T194950) Added 'ApiMaxLagInfo' hook.
 135 * Added 'ApiParseMakeOutputPage' hook.
 136 * The following methods now take a RevisionRecord rather than a Revision. No
 137   external callers are known.
 138   * ApiFeedContributions::feedItemAuthor()
 139   * ApiFeedContributions::feedItemDesc()
 140   * ApiQueryRevisionsBase::extractRevisionInfo()
 141
 142 === Languages updated in 1.32 ===
 143 MediaWiki supports over 350 languages. Many localisations are updated regularly.
 144 Below only new and removed languages are listed, as well as changes to languages
 145 because of Phabricator reports.
 146
 147 * (T193566) Added language support for Ambonese Malay (abs).
 148 * (T194047) Added language support for Shawiya, Latin script (shy-latn).
 149 * (T195940) Added language support for Batak Mandailing (btm).

 152
 153 === Breaking changes in 1.32 ===
 154 * $wgRequestTime, deprecated in 1.25, was removed. Use

 171   * Revision::getRawUserText()
 172   * Revision::getRawComment()
 173 * window.gM() from mediawiki.jqueryMsg, deprecated in 1.23, was removed. Use

 175 * mw.util.escapeId(), deprecated in 1.30, was removed. Use
 176   mw.util.escapeIdForAttribute or mw.util.escapeIdForLink instead.
 177 * mw.util.updateTooltipAccessKeys(), deprecated in 1.24, was removed. Use

 191 * The jquery.farbtastic module, unused since 1.18, was removed.
 192 * (T181318) The $wgStyleVersion setting and its appendage to various script and
 193   style URLs in OutputPage, deprecated in 1.31, was removed.
 194 * The hooks 'PreferencesFormPreSave' and 'PreferencesGetLegend' may provide
 195   any HTMLForm object rather than PreferencesForm.
 196 * The non namespaced TimestampException class, deprecated in 1.29, was removed.
 197   Use Wikimedia\Timestamp\TimestampException instead.
 198 * The global functions codepointToUtf8, hexSequenceToUtf8, utf8ToHexSequence,
 199   utf8ToCodepoint, and escapeSingleString (deprecated in 1.25) were removed.
 200   The UtfNormal\Utils class from the utfnormal library should be used instead.
 201 * The deprecated UTF8_ and UNICODE_ constants were removed. The class constants
 202   from the UtfNormal\Constants class from the utfnormal library should be used
 203 * (T140807) The wgResourceLoaderLESSImportPaths configuration option was removed
 204   from ResourceLoader. Instead, use `@import` statements in LESS to import
 205   files directly from nearby directories within the same project.
 206 * The protected methods PHPSessionHandler::returnSuccess() and returnFailure(),
 207   only needed for PHP5 compatibility, have been removed. It now uses the boolean
 208   values `true` and `false` respectively.
 209 * The $parserMemc global and wfGetParserCacheStorage(), deprecated since 1.30,
 210   were removed. Use the ParserCache class instead.

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