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
  29 === New features in 1.32 ===
  30 * (T112474) Generalized the ResourceLoader mechanism for overriding modules
  31   using a particular page during edit previews.
  32 * (T12331) You can now log page creation events by setting $wgPageCreationLog
  33   to true.
  34 * Added 'ApiParseMakeOutputPage' hook.
  35 * (T174313) Added checkbox on Special:ListUsers to display only users in
  36   temporary user groups.
  37 * (T152462) A cookie can now be set when an IP user is blocked to track that user if
  38   they move to a new IP address. This is disabled by default.
  39 * (T194950) Added 'ApiMaxLagInfo' hook.
  40 * SpecialPage::checkLoginSecurityLevel() will now preserve POST data when
  41   reauthenticating.
  42 * FormSpecialPage::execute() will now call checkLoginSecurityLevel() if
  43   getLoginSecurityLevel() returns non-false.
  44 * The 'ImageBeforeProduceHTML' hook is now passed three new parameters, $parser,
  45   &$query and &$widthOption, allowing extensions even finer control over the resulting
  46   HTML code.
  47
  48 === External library changes in 1.32 ===
  49 * …
  50
  51 ==== Upgraded external libraries ====
  52 * Updated QUnit from 2.4.0 to 2.6.0.
  53 * Updated wikimedia/scoped-callback from 1.0.0 to 2.0.0.
  54 ** ScopedCallback objects can no longer be serialized.
  55 * Updated wikimedia/wrappedstring from 2.3.0 to 3.0.1.
  56
  57 ==== New external libraries ====
  58 * Added wikimedia/xmp-reader 0.5.1
  59 * …
  60
  61 ==== Removed and replaced external libraries ====
  62 * …
  63
  64 === Bug fixes in 1.32 ===
  65 * SpecialPage::execute() will now only call checkLoginSecurityLevel() if
  66   getLoginSecurityLevel() returns non-false.
  67
  68 === Action API changes in 1.32 ===
  69 * Added templated parameters.
  70   * A module can define a templated parameter like "{fruit}-quantity", where
  71     the actual parameters recognized correspond to the values of a multi-valued
  72     parameter. Then clients can make requests like
  73     "fruits=apples|bananas&apples-quantity=1&bananas-quantity=5".
  74   * action=paraminfo will return templated parameter definitions separately
  75     from normal parameters. All parameter definitions now include an "index"
  76     key to allow clients to maintain parameter ordering when merging normal and
  77     templated parameters.
  78 * It is now an error to submit too many values for a multi-valued parameter.
  79   This has generated a warning since MediaWiki 1.14.
  80
  81 === Action API internal changes in 1.32 ===
  82 * Added 'ApiParseMakeOutputPage' hook.
  83 * Parameter names may no longer contain '{' or '}', as these are now used for
  84   templated parameters.
  85 * (T194950) Added 'ApiMaxLagInfo' hook.
  86
  87 === Languages updated in 1.32 ===
  88 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  89 Below only new and removed languages are listed, as well as changes to languages
  90 because of Phabricator reports.
  91
  92 * (T193566) Added language support for Ambonese Malay (abs).
  93 * (T194047) Added language support for Shawiya, Latin script (shy-latn).
  94 * (T195940) Added language support for Batak Mandailing (btm).

 125   and were replaced by RemexHtml.
 126 * (T179624) Job::insert() and ::batchInsert(), deprecated in 1.21, were both
 127   removed. Use JobQueueGroup::singleton()->push() instead.

 132 * The jquery.farbtastic module, unused since 1.18, was removed.
 133 * (T181318) The $wgStyleVersion setting and its appendage to various script and
 134   style URLs in OutputPage, deprecated in 1.31, was removed.
 135 * The hooks 'PreferencesFormPreSave' and 'PreferencesGetLegend' may provide
 136   any HTMLForm object rather than PreferencesForm.
 137 * The non namespaced TimestampException class, deprecated in 1.29, was removed.
 138   Use Wikimedia\Timestamp\TimestampException instead.
 139 * The global functions codepointToUtf8, hexSequenceToUtf8, utf8ToHexSequence,
 140   utf8ToCodepoint, and escapeSingleString (deprecated in 1.25) were removed.
 141   The UtfNormal\Utils class from the utfnormal library should be used instead.
 142 * The deprecated UTF8_ and UNICODE_ constants were removed. The class constants
 143   from the UtfNormal\Constants class from the utfnormal library should be used
 144 * (T140807) The wgResourceLoaderLESSImportPaths configuration option was removed
 145   from ResourceLoader. Instead, use `@import` statements in LESS to import
 146   files directly from nearby directories within the same project.
 147 * The protected methods PHPSessionHandler::returnSuccess() and returnFailure(),
 148   only needed for PHP5 compatibility, have been removed. It now uses the boolean
 149   values `true` and `false` respectively.
 150 * The $parserMemc global and wfGetParserCacheStorage(), deprecated since 1.30,

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