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 means
  26   that a blocked user, even after moving to a new IP address, will still be blocked.
  27 * The archive table's ar_rev_id field is now unique.
  28 * Special:BotPasswords now requires reauthentication.
  29
  30 === New features in 1.32 ===
  31 * (T112474) Generalized the ResourceLoader mechanism for overriding modules
  32   using a particular page during edit previews.
  33 * (T12331) You can now log page creation events by setting $wgPageCreationLog
  34   to true.
  35 * Added 'ApiParseMakeOutputPage' hook.
  36 * (T174313) Added checkbox on Special:ListUsers to display only users in
  37   temporary user groups.
  38 * (T152462) A cookie can now be set when an IP user is blocked to track that user if
  39   they move to a new IP address. This is disabled by default.
  40 * (T194950) Added 'ApiMaxLagInfo' hook.
  41 * SpecialPage::checkLoginSecurityLevel() will now preserve POST data when
  42   reauthenticating.
  43 * FormSpecialPage::execute() will now call checkLoginSecurityLevel() if
  44   getLoginSecurityLevel() returns non-false.
  45 * The 'ImageBeforeProduceHTML' hook is now passed three new parameters, $parser,
  46   &$query and &$widthOption, allowing extensions even finer control over the resulting
  47   HTML code.
  48
  49 === External library changes in 1.32 ===
  50 * …
  51
  52 ==== Upgraded external libraries ====
  53 * Updated QUnit from 2.4.0 to 2.6.0.
  54 * Updated wikimedia/scoped-callback from 1.0.0 to 2.0.0.
  55 ** ScopedCallback objects can no longer be serialized.
  56 * Updated wikimedia/wrappedstring from 2.3.0 to 3.0.1.
  57
  58 ==== New external libraries ====
  59 * Added wikimedia/xmp-reader 0.5.1
  60 * …
  61
  62 ==== Removed and replaced external libraries ====
  63 * …
  64
  65 === Bug fixes in 1.32 ===
  66 * SpecialPage::execute() will now only call checkLoginSecurityLevel() if
  67   getLoginSecurityLevel() returns non-false.
  68
  69 === Action API changes in 1.32 ===
  70 * Added templated parameters.
  71   * A module can define a templated parameter like "{fruit}-quantity", where
  72     the actual parameters recognized correspond to the values of a multi-valued
  73     parameter. Then clients can make requests like
  74     "fruits=apples|bananas&apples-quantity=1&bananas-quantity=5".
  75   * action=paraminfo will return templated parameter definitions separately
  76     from normal parameters. All parameter definitions now include an "index"
  77     key to allow clients to maintain parameter ordering when merging normal and
  78     templated parameters.
  79 * It is now an error to submit too many values for a multi-valued parameter.
  80   This has generated a warning since MediaWiki 1.14.
  81
  82 === Action API internal changes in 1.32 ===
  83 * Added 'ApiParseMakeOutputPage' hook.
  84 * Parameter names may no longer contain '{' or '}', as these are now used for
  85   templated parameters.
  86 * (T194950) Added 'ApiMaxLagInfo' hook.
  87
  88 === Languages updated in 1.32 ===
  89 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  90 Below only new and removed languages are listed, as well as changes to languages
  91 because of Phabricator reports.
  92
  93 * (T193566) Added language support for Ambonese Malay (abs).
  94 * (T194047) Added language support for Shawiya, Latin script (shy-latn).

 138   any HTMLForm object rather than PreferencesForm.
 139 * The non namespaced TimestampException class, deprecated in 1.29, was removed.
 140   Use Wikimedia\Timestamp\TimestampException instead.
 141 * The global functions codepointToUtf8, hexSequenceToUtf8, utf8ToHexSequence,
 142   utf8ToCodepoint, and escapeSingleString (deprecated in 1.25) were removed.
 143   The UtfNormal\Utils class from the utfnormal library should be used instead.
 144 * The deprecated UTF8_ and UNICODE_ constants were removed. The class constants
 145   from the UtfNormal\Constants class from the utfnormal library should be used
 146 * (T140807) The wgResourceLoaderLESSImportPaths configuration option was removed
 147   from ResourceLoader. Instead, use `@import` statements in LESS to import
 148   files directly from nearby directories within the same project.
 149 * The protected methods PHPSessionHandler::returnSuccess() and returnFailure(),
 150   only needed for PHP5 compatibility, have been removed. It now uses the boolean

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