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
  33 === New features in 1.32 ===
  34 * (T112474) Generalized the ResourceLoader mechanism for overriding modules
  35   using a particular page during edit previews.
  36 * (T12331) You can now log page creation events by setting $wgPageCreationLog
  37   to true.
  38 * Added 'ApiParseMakeOutputPage' hook.
  39 * (T174313) Added checkbox on Special:ListUsers to display only users in
  40   temporary user groups.
  41 * (T152462) A cookie can now be set when an IP user is blocked to track that
  42   user if they move to a new IP address. This is disabled by default.
  43 * (T194950) Added 'ApiMaxLagInfo' hook.
  44 * SpecialPage::checkLoginSecurityLevel() will now preserve POST data when
  45   reauthenticating.
  46 * FormSpecialPage::execute() will now call checkLoginSecurityLevel() if
  47   getLoginSecurityLevel() returns non-false.
  48 * The 'ImageBeforeProduceHTML' hook is now passed three new parameters, $parser,
  49   &$query and &$widthOption, allowing extensions even finer control over the
  50   resulting HTML code.
  51
  52 === External library changes in 1.32 ===
  53 * …
  54
  55 ==== Upgraded external libraries ====
  56 * Updated QUnit from 2.4.0 to 2.6.0.
  57 * Updated wikimedia/scoped-callback from 1.0.0 to 2.0.0.
  58 ** ScopedCallback objects can no longer be serialized.
  59 * Updated wikimedia/wrappedstring from 2.3.0 to 3.0.1.
  60
  61 ==== New external libraries ====
  62 * Added wikimedia/xmp-reader 0.5.1
  63 * …
  64
  65 ==== Removed and replaced external libraries ====
  66 * …
  67
  68 === Bug fixes in 1.32 ===
  69 * SpecialPage::execute() will now only call checkLoginSecurityLevel() if
  70   getLoginSecurityLevel() returns non-false.
  71
  72 === Action API changes in 1.32 ===
  73 * Added templated parameters.
  74   * A module can define a templated parameter like "{fruit}-quantity", where
  75     the actual parameters recognized correspond to the values of a multi-valued
  76     parameter. Then clients can make requests like
  77     "fruits=apples|bananas&apples-quantity=1&bananas-quantity=5".
  78   * action=paraminfo will return templated parameter definitions separately
  79     from normal parameters. All parameter definitions now include an "index"
  80     key to allow clients to maintain parameter ordering when merging normal and
  81     templated parameters.
  82 * It is now an error to submit too many values for a multi-valued parameter.
  83   This has generated a warning since MediaWiki 1.14.
  84 * Assertion failures from the 'assert' and 'assertuser' parameters will no
  85   longer use the action module's custom response format, for the few modules
  86   that use custom formatters that handle errors.
  87
  88 === Action API internal changes in 1.32 ===
  89 * Added 'ApiParseMakeOutputPage' hook.
  90 * Parameter names may no longer contain '{' or '}', as these are now used for
  91   templated parameters.
  92 * (T194950) Added 'ApiMaxLagInfo' hook.
  93
  94 === Languages updated in 1.32 ===
  95 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  96 Below only new and removed languages are listed, as well as changes to languages
  97 because of Phabricator reports.
  98
  99 * (T193566) Added language support for Ambonese Malay (abs).
 100 * (T194047) Added language support for Shawiya, Latin script (shy-latn).

 148 * The non namespaced TimestampException class, deprecated in 1.29, was removed.
 149   Use Wikimedia\Timestamp\TimestampException instead.
 150 * The global functions codepointToUtf8, hexSequenceToUtf8, utf8ToHexSequence,

 157   files directly from nearby directories within the same project.
 158 * The protected methods PHPSessionHandler::returnSuccess() and returnFailure(),
 159   only needed for PHP5 compatibility, have been removed. It now uses the boolean

 164   instead.
 165 * Support for ResourceLoaderModule::getModifiedTime() and getModifiedHash(),

 167 * (T195256) Skins are recommended not to rely on JavaScript for the "mw-jump"
 168   and "jump-to-nav" accessibility links. To this end, the "jquery.mw-jump"
 169   is no longer loaded by default. The Vector and MonoBook skins have made a
 170   minor change to implement the toggle feature with CSS instead. To restore
 171   prior functionality, either explicitly load "jquery.mw-jump" in your skin
 172   or refer to T195256 for details on how to make the same change.
 173 * Hook 'EditPageBeforeEditChecks' was removed;
 174   use 'EditPageGetCheckboxesDefinition' instead.
 175 * Linker::getLinkColour() and DummyLinker::getLinkColour(), deprecated since
 176   1.28, were removed. LinkRenderer::getLinkClasses() should be used instead.

 178   been removed. Use Wikimedia\Rdbms\LoadBalancer::getLaggedReplicaMode()
 179   instead.

 181   CapsuleMultiselectWidget. The following methods may no longer be used:
 182   * setItemsFromData: Use setValue instead
 183   * getItemsData: Use getItems instead and get the data property
 184
 185 === Deprecations in 1.32 ===
 186 * Use of a StartProfiler.php file is deprecated in favour of placing
 187   configuration in LocalSettings.php.
 188 * HTMLForm::setSubmitProgressive() is deprecated. No need to call it. Submit
 189   button is already marked as progressive.
 190 * Skin::setupSkinUserCss() is deprecated. Adding of modules to load
 191   has been centralised to Skin::getDefaultModules(), which is now capable
 192   of queueing style modules as well.
 193 * OutputPage::addModuleScripts() and ParserOutput::addModuleScripts are
 194   deprecated. Use addModules() instead.
 195 * Overriding SearchEngine::{searchText,searchTitle,searchArchiveTitle}
 196   in extending classes is deprecated.  Extend related doSearch* methods
 197   instead.
 198 * CollationFa has been removed completely as it's not needed anymore
 199 * The following 'mediawiki.api' plugin modules were merged into mediawiki.api
 200   and deprecated: mediawiki.api.category, mediawiki.api.edit,
 201   mediawiki.api.login, mediawiki.api.options, mediawiki.api.parse,
 202   mediawiki.api.upload, mediawiki.api.user, mediawiki.api.watch,
 203   mediawiki.api.messages, and mediawiki.api.rollback.
 204 * ApiBase::truncateArray() is deprecated. No replacement, as nothing is known
 205   to use it.
 206 * WatchAction::getUnwatchToken is deprecated. Use WatchAction::getWatchToken
 207   with the 'unwatch' action parameter instead.
 208 * IcuCollation::getICUVersion() is deprecated, as you can just use the PHP
 209   constant INTL_ICU_VERSION directly in all versions that MediaWiki supports.
 210 * Parser::fetchFile() is deprecated. Use ::fetchFileAndTitle() instead.
 211 * The ApiQueryContributions class has been renamed to ApiQueryUserContribs.
 212 * The XMPInfo, XMPReader, and XMPValidate classes have been deprecated in favor
 213   of the namespaced classes provided by the wikimedia/xmp-reader library.
 214 * SearchResultSet::{next,rewind} are deprecated. Calling code should
 215   use foreach on the SearchResultSet, or the extractResults method. Extending
 216   code should override extractResults.
 217 * Instantiating SearchResultSet directly is deprecated. SearchEngine
 218   implementations must subclass SearchResultSet for their purposes.
 219 * SearchResult::setExtensionData argument has been changed from accepting an
 220   array to accepting a Closure that returns the array when called.
 221 * Class CryptRand, everything in MWCryptRand except generateHex() and function
 222   MediaWikiServices::getCryptRand() are deprecated, use random_bytes() to
 223   generate cryptographically secure random byte sequences.
 224 * Parser::getConverterLanguage() is deprecated.  Use ::getTargetLanguage()
 225   instead.
 226 * Language::markNoConversion() is deprecated.  It confused readers because
 227   it had unexpected behavior (only marking text if it looked like a URL)
 228   and was only used in a single place in the code.  Use
 229   LanguageConverter::markNoConversion() instead.
 230 * (T176526) EditPage::getContextTitle() falling back to $wgTitle when the
 231   context title is unset is now deprecated; anything creating an EditPage
 232   instance should set the context title via ::setContextTitle().
 233 * The 'jquery.hidpi' module (polyfill for IMG srcset) is deprecated.
 234 * ResourceLoaderStartUpModule::getStartupModules() and ::getLegacyModules()
 235   are deprecated. These concepts are obsolete and have no replacement.
 236 * String type for $lang of DifferenceEngine::setTextLanguage is deprecated.
 237
 238 === Other changes in 1.32 ===
 239 * …
 240
 241 == Compatibility ==
 242 MediaWiki 1.32 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 243 supported, it is generally advised to use PHP 7.0.0 or later for long term
 244 support.
 245
 246 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 247 but support for them is somewhat less mature. There is experimental support for
 248 Oracle and Microsoft SQL Server.
 249
 250 The supported versions are:
 251
 252 * MySQL 5.5.8 or later
 253 * PostgreSQL 9.2 or later
 254 * SQLite 3.3.7 or later
 255 * Oracle 9.0.1 or later
 256 * Microsoft SQL Server 2005 (9.00.1399)
 257
 258 == Upgrading ==
 259 1.32 has several database changes since 1.31, and will not work without schema
 260 updates. Note that due to changes to some very large tables like the revision
 261 table, the schema update may take quite long (minutes on a medium sized site,
 262 many hours on a large site).
 263
 264 Don't forget to always back up your database before upgrading!
 265
 266 See the file UPGRADE for more detailed upgrade instructions, including
 267 important information when upgrading from versions prior to 1.11.
 268
 269 For notes on 1.31.x and older releases, see HISTORY.
 270
 271 == Online documentation ==
 272 Documentation for both end-users and site administrators is available on
 273 MediaWiki.org, and is covered under the GNU Free Documentation License (except
 274 for pages that explicitly state that their contents are in the public domain):
 275
 276        https://www.mediawiki.org/wiki/Special:MyLanguage/Documentation
 277
 278 == Mailing list ==
 279 A mailing list is available for MediaWiki user support and discussion:
 280
 281        https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 282
 283 A low-traffic announcements-only list is also available:
 284
 285        https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
