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 default quality of JPEG thumbnails generated by GD was reduced from 95 to
  14   80. The quality of JPEG thumbnails is now configurable through the new setting
  15   $wgJpegQuality (default 80). This aligns the quality to what ImageMagick uses.
  16 * $wgExperimentalHtmlIds, deprecated since 1.30, has been removed. The
  17   'html5-legacy' value for $wgFragmentMode is no longer accepted.
  18 * The experimental Html5Internal and Html5Depurate tidy drivers were removed.
  19   RemexHtml, which is the default, should be used instead.
  20 * (T135963) You can now define a Content Security Policy for your wiki. This
  21   adds a defense-in-depth feature to stop an attacker who has found a bug in
  22   the parser allowing them to insert malicious attributes. Disabled by default,
  23   you can configure this via $wgCSPHeader and $wgCSPReportOnlyHeader.
  24 * New configuration variable has been added: $wgCookieSetOnIpBlock.
  25   This determines whether to set a cookie when an IP user is blocked. Doing so
  26   means that a blocked user, even after moving to a new IP address, will still
  27   be blocked.
  28 * The archive table's ar_rev_id field is now unique.
  29 * Special:BotPasswords now requires reauthentication.
  30
  31 === New features in 1.32 ===
  32 * (T112474) Generalized the ResourceLoader mechanism for overriding modules
  33   using a particular page during edit previews.
  34 * (T12331) You can now log page creation events by setting $wgPageCreationLog
  35   to true.
  36 * Added 'ApiParseMakeOutputPage' hook.
  37 * (T174313) Added checkbox on Special:ListUsers to display only users in
  38   temporary user groups.
  39 * (T152462) A cookie can now be set when an IP user is blocked to track that
  40   user if they move to a new IP address. This is disabled by default.
  41 * (T194950) Added 'ApiMaxLagInfo' hook.
  42 * SpecialPage::checkLoginSecurityLevel() will now preserve POST data when
  43   reauthenticating.
  44 * FormSpecialPage::execute() will now call checkLoginSecurityLevel() if
  45   getLoginSecurityLevel() returns non-false.
  46 * The 'ImageBeforeProduceHTML' hook is now passed three new parameters, $parser,
  47   &$query and &$widthOption, allowing extensions even finer control over the
  48   resulting HTML code.
  49
  50 === External library changes in 1.32 ===
  51 * …
  52
  53 ==== Upgraded external libraries ====
  54 * Updated QUnit from 2.4.0 to 2.6.0.
  55 * Updated wikimedia/scoped-callback from 1.0.0 to 2.0.0.
  56 ** ScopedCallback objects can no longer be serialized.
  57 * Updated wikimedia/wrappedstring from 2.3.0 to 3.0.1.
  58
  59 ==== New external libraries ====
  60 * Added wikimedia/xmp-reader 0.5.1
  61 * …
  62
  63 ==== Removed and replaced external libraries ====
  64 * …
  65
  66 === Bug fixes in 1.32 ===
  67 * SpecialPage::execute() will now only call checkLoginSecurityLevel() if
  68   getLoginSecurityLevel() returns non-false.
  69
  70 === Action API changes in 1.32 ===
  71 * Added templated parameters.
  72   * A module can define a templated parameter like "{fruit}-quantity", where
  73     the actual parameters recognized correspond to the values of a multi-valued
  74     parameter. Then clients can make requests like
  75     "fruits=apples|bananas&apples-quantity=1&bananas-quantity=5".
  76   * action=paraminfo will return templated parameter definitions separately
  77     from normal parameters. All parameter definitions now include an "index"
  78     key to allow clients to maintain parameter ordering when merging normal and
  79     templated parameters.
  80 * It is now an error to submit too many values for a multi-valued parameter.
  81   This has generated a warning since MediaWiki 1.14.
  82 * Assertion failures from the 'assert' and 'assertuser' parameters will no
  83   longer use the action module's custom response format, for the few modules
  84   that use custom formatters that handle errors.
  85
  86 === Action API internal changes in 1.32 ===
  87 * Added 'ApiParseMakeOutputPage' hook.
  88 * Parameter names may no longer contain '{' or '}', as these are now used for
  89   templated parameters.
  90 * (T194950) Added 'ApiMaxLagInfo' hook.
  91
  92 === Languages updated in 1.32 ===
  93 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  94 Below only new and removed languages are listed, as well as changes to languages
  95 because of Phabricator reports.
  96

 145   any HTMLForm object rather than PreferencesForm.
 146 * The non namespaced TimestampException class, deprecated in 1.29, was removed.
 147   Use Wikimedia\Timestamp\TimestampException instead.
 148 * The global functions codepointToUtf8, hexSequenceToUtf8, utf8ToHexSequence,

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

 165 * (T195256) Skins are recommended not to rely on JavaScript for the "mw-jump"
 166   and "jump-to-nav" accessibility links. To this end, the "jquery.mw-jump"
 167   is no longer loaded by default. The Vector and MonoBook skins have made a
 168   minor change to implement the toggle feature with CSS instead. To restore
 169   prior functionality, either explicitly load "jquery.mw-jump" in your skin
 170   or refer to T195256 for details on how to make the same change.
 171 * Hook 'EditPageBeforeEditChecks' was removed;
 172   use 'EditPageGetCheckboxesDefinition' instead.
 173 * Linker::getLinkColour() and DummyLinker::getLinkColour(), deprecated since
 174   1.28, were removed. LinkRenderer::getLinkClasses() should be used instead.
 175 * mw.widgets.CategoryMultiselectWidget now uses TagMultiselectWidget instead of
 176   CapsuleMultiselectWidget. The following methods may no longer be used:
 177   * setItemsFromData: Use setValue instead
 178   * getItemsData: Use getItems instead and get the data property
 179
 180 === Deprecations in 1.32 ===
 181 * Use of a StartProfiler.php file is deprecated in favour of placing
 182   configuration in LocalSettings.php.
 183 * HTMLForm::setSubmitProgressive() is deprecated. No need to call it. Submit
 184   button is already marked as progressive.
 185 * Skin::setupSkinUserCss() is deprecated. Adding of modules to load
 186   has been centralised to Skin::getDefaultModules(), which is now capable
 187   of queueing style modules as well.
 188 * OutputPage::addModuleScripts() and ParserOutput::addModuleScripts are
 189   deprecated. Use addModules() instead.
 190 * Overriding SearchEngine::{searchText,searchTitle,searchArchiveTitle}
 191   in extending classes is deprecated.  Extend related doSearch* methods
 192   instead.
 193 * CollationFa has been removed completely as it's not needed anymore
 194 * The following 'mediawiki.api' plugin modules were merged into mediawiki.api
 195   and deprecated: mediawiki.api.category, mediawiki.api.edit,
 196   mediawiki.api.login, mediawiki.api.options, mediawiki.api.parse,
 197   mediawiki.api.upload, mediawiki.api.user, mediawiki.api.watch,
 198   mediawiki.api.messages, and mediawiki.api.rollback.
 199 * ApiBase::truncateArray() is deprecated. No replacement, as nothing is known
 200   to use it.
 201 * WatchAction::getUnwatchToken is deprecated. Use WatchAction::getWatchToken
 202   with the 'unwatch' action parameter instead.
 203 * IcuCollation::getICUVersion() is deprecated, as you can just use the PHP
 204   constant INTL_ICU_VERSION directly in all versions that MediaWiki supports.
 205 * Parser::fetchFile() is deprecated. Use ::fetchFileAndTitle() instead.
 206 * The ApiQueryContributions class has been renamed to ApiQueryUserContribs.
 207 * The XMPInfo, XMPReader, and XMPValidate classes have been deprecated in favor
 208   of the namespaced classes provided by the wikimedia/xmp-reader library.
 209 * SearchResultSet::{next,rewind} are deprecated. Calling code should
 210   use foreach on the SearchResultSet, or the extractResults method. Extending
 211   code should override extractResults.
 212 * Instantiating SearchResultSet directly is deprecated. SearchEngine
 213   implementations must subclass SearchResultSet for their purposes.
 214 * SearchResult::setExtensionData argument has been changed from accepting an
 215   array to accepting a Closure that returns the array when called.
 216 * Class CryptRand, everything in MWCryptRand except generateHex() and function
 217   MediaWikiServices::getCryptRand() are deprecated, use random_bytes() to
 218   generate cryptographically secure random byte sequences.
 219 * Parser::getConverterLanguage() is deprecated.  Use ::getTargetLanguage()
 220   instead.
 221 * Language::markNoConversion() is deprecated.  It confused readers because
 222   it had unexpected behavior (only marking text if it looked like a URL)
 223   and was only used in a single place in the code.  Use
 224   LanguageConverter::markNoConversion() instead.
 225 * (T176526) EditPage::getContextTitle() falling back to $wgTitle when the
 226   context title is unset is now deprecated; anything creating an EditPage
 227   instance should set the context title via ::setContextTitle().
 228 * The 'jquery.hidpi' module (polyfill for IMG srcset) is deprecated.
 229 * ResourceLoaderStartUpModule::getStartupModules() and ::getLegacyModules()
 230   are deprecated. These concepts are obsolete and have no replacement.
 231 * String type for $lang of DifferenceEngine::setTextLanguage is deprecated.
 232
 233 === Other changes in 1.32 ===
 234 * …
 235
 236 == Compatibility ==
 237 MediaWiki 1.32 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 238 supported, it is generally advised to use PHP 7.0.0 or later for long term
 239 support.
 240
 241 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 242 but support for them is somewhat less mature. There is experimental support for
 243 Oracle and Microsoft SQL Server.
 244
 245 The supported versions are:
 246
 247 * MySQL 5.5.8 or later
 248 * PostgreSQL 9.2 or later
 249 * SQLite 3.3.7 or later
 250 * Oracle 9.0.1 or later
 251 * Microsoft SQL Server 2005 (9.00.1399)
 252
 253 == Upgrading ==
 254 1.32 has several database changes since 1.31, and will not work without schema
 255 updates. Note that due to changes to some very large tables like the revision
 256 table, the schema update may take quite long (minutes on a medium sized site,
 257 many hours on a large site).
 258
 259 Don't forget to always back up your database before upgrading!
 260
 261 See the file UPGRADE for more detailed upgrade instructions, including
 262 important information when upgrading from versions prior to 1.11.
 263

 265
 266 == Online documentation ==
 267 Documentation for both end-users and site administrators is available on
 268 MediaWiki.org, and is covered under the GNU Free Documentation License (except
 269 for pages that explicitly state that their contents are in the public domain):
 270
 271        https://www.mediawiki.org/wiki/Special:MyLanguage/Documentation
 272
 273 == Mailing list ==
 274 A mailing list is available for MediaWiki user support and discussion:
 275
 276        https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 277
 278 A low-traffic announcements-only list is also available:
