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

  87
  88 === Bug fixes in 1.32 ===
  89 * SpecialPage::execute() will now only call checkLoginSecurityLevel() if
  90   getLoginSecurityLevel() returns non-false.
  91
  92 === Action API changes in 1.32 ===
  93 * Added templated parameters.
  94   * A module can define a templated parameter like "{fruit}-quantity", where
  95     the actual parameters recognized correspond to the values of a multi-valued
  96     parameter. Then clients can make requests like
  97     "fruits=apples|bananas&apples-quantity=1&bananas-quantity=5".
  98   * action=paraminfo will return templated parameter definitions separately
  99     from normal parameters. All parameter definitions now include an "index"
 100     key to allow clients to maintain parameter ordering when merging normal and
 101     templated parameters.
 102 * It is now an error to submit too many values for a multi-valued parameter.
 103   This has generated a warning since MediaWiki 1.14.
 104 * Assertion failures from the 'assert' and 'assertuser' parameters will no
 105   longer use the action module's custom response format, for the few modules
 106   that use custom formatters that handle errors.
 107 * (T198935) User list preferences such as `email-blacklist` and similar
 108   extension preferences are no longer represented as arrays when returned by
 109   action=query&meta=userinfo&uiprop=options.
 110 * 'missingparam' errors will now use the prefixed parameter name in the code
 111   and error text, e.g. "noxxfoo" and "The 'xxfoo' parameter must be set" rather
 112   than "nofoo" and "The 'foo' parameter must be set".
 113 * action=query&prop=revisions now takes a 'rvslots' parameter to indicate the
 114   multi-content revision slots for which content should be returned. It also
 115   has a new rvprop, 'roles', to indicate which roles have slots. A deprecation
 116   warning will be issued if rvprop=content or rvprop=contentmodel are used
 117   without rvslots.
 118 * The rvcontentformat parameter to action=query&prop=revisions has been
 119   deprecated. Clients should be prepared to deal with the default format for
 120   relevant models.
 121 * Use of the deprecated parameters rvexpandtemplates, rvgeneratexml, rvparse,
 122   rvdiffto, rvdifftotext, rvdifftotextpst, rvcontentformat, or the deprecated
 123   rvprop=parsetree is forbidden with the new 'rvslots' parameter.
 124 * action=query&prop=deletedrevisions, action=query&list=allrevisions, and
 125   action=query&list=alldeletedrevisions are changed similarly to
 126   &prop=revisions (see the three previous items).
 127
 128 === Action API internal changes in 1.32 ===
 129 * Added 'ApiParseMakeOutputPage' hook.
 130 * Parameter names may no longer contain '{' or '}', as these are now used for
 131   templated parameters.
 132 * (T194950) Added 'ApiMaxLagInfo' hook.
 133 * Added 'ApiParseMakeOutputPage' hook.
 134 * The following methods now take a RevisionRecord rather than a Revision. No
 135   external callers are known.
 136   * ApiFeedContributions::feedItemAuthor()
 137   * ApiFeedContributions::feedItemDesc()
 138   * ApiQueryRevisionsBase::extractRevisionInfo()
 139
 140 === Languages updated in 1.32 ===
 141 MediaWiki supports over 350 languages. Many localisations are updated regularly.
 142 Below only new and removed languages are listed, as well as changes to languages
 143 because of Phabricator reports.
 144
 145 * (T193566) Added language support for Ambonese Malay (abs).
 146 * (T194047) Added language support for Shawiya, Latin script (shy-latn).

 150
 151 === Breaking changes in 1.32 ===
 152 * $wgRequestTime, deprecated in 1.25, was removed. Use

 188   removed. Use mediawiki.widgets.visibleLengthLimit instead.
 189 * The jquery.farbtastic module, unused since 1.18, was removed.
 190 * (T181318) The $wgStyleVersion setting and its appendage to various script and
 191   style URLs in OutputPage, deprecated in 1.31, was removed.
 192 * The hooks 'PreferencesFormPreSave' and 'PreferencesGetLegend' may provide
 193   any HTMLForm object rather than PreferencesForm.
 194 * The non namespaced TimestampException class, deprecated in 1.29, was removed.
 195   Use Wikimedia\Timestamp\TimestampException instead.
 196 * The global functions codepointToUtf8, hexSequenceToUtf8, utf8ToHexSequence,

 198   The UtfNormal\Utils class from the utfnormal library should be used instead.
 199 * The deprecated UTF8_ and UNICODE_ constants were removed. The class constants
 200   from the UtfNormal\Constants class from the utfnormal library should be used
 201 * (T140807) The wgResourceLoaderLESSImportPaths configuration option was removed
 202   from ResourceLoader. Instead, use `@import` statements in LESS to import
 203   files directly from nearby directories within the same project.
 204 * The protected methods PHPSessionHandler::returnSuccess() and returnFailure(),
 205   only needed for PHP5 compatibility, have been removed. It now uses the boolean
 206   values `true` and `false` respectively.
 207 * The $parserMemc global and wfGetParserCacheStorage(), deprecated since 1.30,
 208   were removed. Use the ParserCache class instead.
 209 * ScopedCallback (deprecated in 1.28) was removed. Use Wikimedia\ScopedCallback
 210   instead.
 211 * Support for ResourceLoaderModule::getModifiedTime() and getModifiedHash(),
 212   deprecated since 1.26, was removed. Use getDefinitionSummary() instead.
 213 * (T195256) Skins are recommended not to rely on JavaScript for the "mw-jump"
 214   and "jump-to-nav" accessibility links. To this end, the "jquery.mw-jump"
 215   is no longer loaded by default. The Vector and MonoBook skins have made a
 216   minor change to implement the toggle feature with CSS instead. To restore
 217   prior functionality, either explicitly load "jquery.mw-jump" in your skin
 218   or refer to T195256 for details on how to make the same change.
 219 * Hook 'EditPageBeforeEditChecks' was removed;
 220   use 'EditPageGetCheckboxesDefinition' instead.
 221 * Linker::getLinkColour() and DummyLinker::getLinkColour(), deprecated since
 222   1.28, were removed. LinkRenderer::getLinkClasses() should be used instead.
 223 * Wikimedia\Rdbms\LoadBalancer::getLaggedSlaveMode(), deprecated in 1.28, has
 224   been removed. Use Wikimedia\Rdbms\LoadBalancer::getLaggedReplicaMode()
 225   instead.
 226 * mw.widgets.CategoryMultiselectWidget now uses TagMultiselectWidget instead of
 227   CapsuleMultiselectWidget. The following methods may no longer be used:
 228   * setItemsFromData: Use setValue instead
 229   * getItemsData: Use getItems instead and get the data property
 230 * Two OutputPage methods, addMetadataLink() and getMetadataAttribute(), were
 231   removed.  Use addLink() instead.
 232
 233 === Deprecations in 1.32 ===
 234 * Use of a StartProfiler.php file is deprecated in favour of placing
 235   configuration in LocalSettings.php.
 236 * HTMLForm::setSubmitProgressive() is deprecated. No need to call it. Submit
 237   button is already marked as progressive.
 238 * Skin::setupSkinUserCss() is deprecated. Adding of modules to load
 239   has been centralised to Skin::getDefaultModules(), which is now capable
 240   of queueing style modules as well.
 241 * OutputPage::addModuleScripts() and ParserOutput::addModuleScripts are
 242   deprecated. Use addModules() instead.
 243 * Overriding SearchEngine::{searchText,searchTitle,searchArchiveTitle}
 244   in extending classes is deprecated.  Extend related doSearch* methods
 245   instead.
 246 * CollationFa has been removed completely as it's not needed anymore
 247 * The following 'mediawiki.api' plugin modules were merged into mediawiki.api
 248   and deprecated: mediawiki.api.category, mediawiki.api.edit,
 249   mediawiki.api.login, mediawiki.api.options, mediawiki.api.parse,
 250   mediawiki.api.upload, mediawiki.api.user, mediawiki.api.watch,
 251   mediawiki.api.messages, and mediawiki.api.rollback.
 252 * ApiBase::truncateArray() is deprecated. No replacement, as nothing is known
 253   to use it.
 254 * WatchAction::getUnwatchToken is deprecated. Use WatchAction::getWatchToken
 255   with the 'unwatch' action parameter instead.
 256 * IcuCollation::getICUVersion() is deprecated, as you can just use the PHP
 257   constant INTL_ICU_VERSION directly in all versions that MediaWiki supports.
 258 * Parser::fetchFile() is deprecated. Use ::fetchFileAndTitle() instead.
 259 * The ApiQueryContributions class has been renamed to ApiQueryUserContribs.
 260 * The XMPInfo, XMPReader, and XMPValidate classes have been deprecated in favor
 261   of the namespaced classes provided by the wikimedia/xmp-reader library.
 262 * SearchResultSet::{next,rewind} are deprecated. Calling code should
 263   use foreach on the SearchResultSet, or the extractResults method. Extending
 264   code should override extractResults.
 265 * Instantiating SearchResultSet directly is deprecated. SearchEngine
 266   implementations must subclass SearchResultSet for their purposes.
 267 * SearchResult::setExtensionData argument has been changed from accepting an
 268   array to accepting a Closure that returns the array when called.
 269 * Class CryptRand, everything in MWCryptRand except generateHex() and function
 270   MediaWikiServices::getCryptRand() are deprecated, use random_bytes() to
 271   generate cryptographically secure random byte sequences.
 272 * Parser::getConverterLanguage() is deprecated.  Use ::getTargetLanguage()
 273   instead.
 274 * Language::markNoConversion() is deprecated.  It confused readers because
 275   it had unexpected behavior (only marking text if it looked like a URL)
 276   and was only used in a single place in the code.  Use
 277   LanguageConverter::markNoConversion() instead.
 278 * (T197492) Language::truncate() was soft deprecated in 1.31 and is
 279   hard deprecated in this release.  It has been split into two similar
 280   methods, Language::truncateForVisual() and Language::truncateForDatabase(),
 281   which measure length in characters and bytes, respectively.  Use
 282   Language::truncateForVisual() when possible to provide equity to users
 283   of multibyte scripts.
 284 * (T176526) EditPage::getContextTitle() falling back to $wgTitle when the
 285   context title is unset is now deprecated; anything creating an EditPage
 286   instance should set the context title via ::setContextTitle().
 287 * The 'jquery.hidpi' module (polyfill for IMG srcset) is deprecated.
 288 * ResourceLoaderStartUpModule::getStartupModules() and ::getLegacyModules()
 289   are deprecated. These concepts are obsolete and have no replacement.
 290 * String type for $lang of DifferenceEngine::setTextLanguage is deprecated.
 291 * The following methods of OutputPage are now deprecated in favour
 292   of using showFatalError directly: OutputPage::showFileDeleteError()
 293   OutputPage::showFileNotFoundError(), OutputPage::showFileRenameError()
 294   OutputPage::showFileCopyError() and OutputPage::showUnexpectedValueError().
 295 * The Replacer, DoubleReplacer, HashtableReplacer, and RegexlikeReplacer
 296   classes are now deprecated. Use a Closure instead.
 297 * (T194263) ContentHandler::makeParserOptions() is deprecated. Use
 298   WikiPage::makeParserOptions() or ParserOptions::newCanonical() instead.
 299 * (T100681) Use of the Parsoid v1 API with the VirtualRESTService, deprecated in
 300   MediaWiki 1.26,  is now hard-deprecated. All known clients were converted to
 301   the Parsoid v3 API in May 2015.
 302 * $input is deprecated in hook 'LogEventsListGetExtraInputs'. Use
 303   $formDescriptor instead.
 304 * SearchEngine::transformSearchTerm( $term ) should no longer be called prior
 305   to running searchText. This method was mainly implemented to support the
 306   'prefix' URI param in SpecialSearch, but there are no reasons to expose this
 307   logic as it should be handled internally by SearchEngine implementations
 308   supporting this feature. SearchEngine implementations should no longer
 309   override this methods.
 310 * SearchEngine::replacePrefixes( $query ) should no longer be called prior
 311   to running searchText/searchTitle.
 312 * (T199657) Messages for $wgFilterLogTypes labels should be no longer be in the
 313   'log-show-hide-[type]' format. Instead use 'logeventslist-[type]-log'.
 314 * Global functions  wfArrayFilter() and wfArrayFilterByKey() are deprecated.
 315   use array_filter() directly.
 316 * The $wgShowSQLErrors global is deprecated and nonfunctional.
 317   Set $wgShowExceptionDetails and/or $wgShowHostnames instead.
 318 * The $wgShowDBErrorBacktrace global is deprecated and nonfunctional.
 319   Set $wgShowExceptionDetails instead.
 320 * Public access to the DifferenceEngine properties mOldid, mNewid, mOldPage,
 321   mNewPage, mOldContent, mNewContent, mRevisionsLoaded, mTextLoaded and
 322   mCacheHit is deprecated. Use getOldid() / getNewid() for the first two,
 323   do your own lookup for page/content. mNewRev / mOldRev remains public.
 324 * The $wgExternalDiffEngine value 'wikidiff2' is deprecated. To use wikidiff2
 325   just enable the PHP extension, and it will be autodetected.
 326 * The wfUseMW function, soft-deprecated in 1.26, is now hard deprecated.
 327
 328 === Other changes in 1.32 ===
 329 * (T198811) The following tables have had their UNIQUE indexes turned into
 330   proper PRIMARY KEYs for increased maintainability: interwiki, page_props,
 331   protected_titles and site_identifiers.
 332 * …
 333
 334 == Compatibility ==
 335 MediaWiki 1.32 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 336 supported, it is generally advised to use PHP 7.0.0 or later for long term
 337 support.
 338
 339 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 340 but support for them is somewhat less mature. There is experimental support for
 341 Oracle and Microsoft SQL Server.
 342
 343 The supported versions are:
 344
 345 * MySQL 5.5.8 or later
 346 * PostgreSQL 9.2 or later
 347 * SQLite 3.3.7 or later
 348 * Oracle 9.0.1 or later
 349 * Microsoft SQL Server 2005 (9.00.1399)
 350
 351 == Upgrading ==
 352 1.32 has several database changes since 1.31, and will not work without schema
 353 updates. Note that due to changes to some very large tables like the revision
 354 table, the schema update may take quite long (minutes on a medium sized site,
 355 many hours on a large site).
 356
 357 Don't forget to always back up your database before upgrading!
 358
 359 See the file UPGRADE for more detailed upgrade instructions, including
 360 important information when upgrading from versions prior to 1.11.
 361
 362 For notes on 1.31.x and older releases, see HISTORY.
 363
 364 == Online documentation ==
 365 Documentation for both end-users and site administrators is available on
 366 MediaWiki.org, and is covered under the GNU Free Documentation License (except
 367 for pages that explicitly state that their contents are in the public domain):
 368
 369        https://www.mediawiki.org/wiki/Special:MyLanguage/Documentation
 370
 371 == Mailing list ==
 372 A mailing list is available for MediaWiki user support and discussion:
 373
 374        https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 375
 376 A low-traffic announcements-only list is also available:
 377
 378        https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 379
 380 It's highly recommended that you sign up for one of these lists if you're
 381 going to run a public MediaWiki, so you can be notified of security fixes.
 382
 383 == IRC help ==
 384 There's usually someone online in #mediawiki on irc.freenode.net.
