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
  25 === New features in 1.32 ===
  26 * (T112474) Generalized the ResourceLoader mechanism for overriding modules
  27   using a particular page during edit previews.
  28 * Added 'ApiParseMakeOutputPage' hook.
  29 * (T174313) Added checkbox on Special:ListUsers to display only users in
  30   temporary user groups.

  44 === Bug fixes in 1.32 ===
  45 * …
  46
  47 === Action API changes in 1.32 ===
  48 * Added templated parameters.
  49   * A module can define a templated parameter like "{fruit}-quantity", where
  50     the actual parameters recognized correspond to the values of a multi-valued
  51     parameter. Then clients can make requests like
  52     "fruits=apples|bananas&apples-quantity=1&bananas-quantity=5".
  53   * action=paraminfo will return templated parameter definitions separately
  54     from normal parameters. All parameter definitions now include an "index"
  55     key to allow clients to maintain parameter ordering when merging normal and
  56     templated parameters.
  57 * It is now an error to submit too many values for a multi-valued parameter.
  58   This has generated a warning since MediaWiki 1.14.
  59
  60 === Action API internal changes in 1.32 ===
  61 * Added 'ApiParseMakeOutputPage' hook.
  62 * Parameter names may no longer contain '{' or '}', as these are now used for
  63   templated parameters.
  64
  65 === Languages updated in 1.32 ===
  66 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  67 Below only new and removed languages are listed, as well as changes to languages
  68 because of Phabricator reports.
  69
  70 * (T193566) Added language support for Ambonese Malay (abs).
  71 * (T194047) Added language support for Shawiya, Latin script (shy-latn).
  72
  73 === Breaking changes in 1.32 ===

 122 === Deprecations in 1.32 ===
 123 * Use of a StartProfiler.php file is deprecated in favour of placing
 124   configuration in LocalSettings.php.
 125 * HTMLForm::setSubmitProgressive() is deprecated. No need to call it. Submit
 126   button is already marked as progressive.
 127 * Skin::setupSkinUserCss() is deprecated. Adding of modules to load
 128   has been centralised to Skin::getDefaultModules(), which is now capable
 129   of queueing style modules as well.
 130 * OutputPage::addModuleScripts() and ParserOutput::addModuleScripts are
 131   deprecated. Use addModules() instead.
 132 * Overriding SearchEngine::{searchText,searchTitle,searchArchiveTitle}
 133   in extending classes is deprecated.  Extend related doSearch* methods
 134   instead.
 135 * CollationFa has been removed completely as it's not needed anymore
 136 * The following 'mediawiki.api' plugin modules were merged into mediawiki.api
 137   and deprecated: mediawiki.api.category, mediawiki.api.edit,
 138   mediawiki.api.login, mediawiki.api.options, mediawiki.api.parse,
 139   mediawiki.api.upload, mediawiki.api.user, mediawiki.api.watch,
 140   mediawiki.api.messages, and mediawiki.api.rollback.
 141 * ApiBase::truncateArray() is deprecated. No replacement, as nothing is known
 142   to use it.
 143 * WatchAction::getUnwatchToken is deprecated. Use WatchAction::getWatchToken
 144   with the 'unwatch' action parameter instead.
 145 * IcuCollation::getICUVersion() is deprecated, as you can just use the PHP
 146   constant INTL_ICU_VERSION directly in all versions that MediaWiki supports.
 147
 148 === Other changes in 1.32 ===
 149 * Soft hyphens (U+00AD) are now automatically removed from titles; these
 150   characters can accidentally end up in copy-and-pasted titles.
 151 * Strip Unicode 6.3.0 directional formatting characters (U+061C, U+2066,
 152   U+2067, U+2068, U+2069) from the title.
 153 * …
 154
 155 == Compatibility ==
 156 MediaWiki 1.32 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 157 supported, it is generally advised to use PHP 7.0.0 or later for long term
 158 support.
 159
 160 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 161 but support for them is somewhat less mature. There is experimental support for
 162 Oracle and Microsoft SQL Server.
 163
 164 The supported versions are:
 165
 166 * MySQL 5.5.8 or later
 167 * PostgreSQL 9.2 or later
 168 * SQLite 3.3.7 or later
 169 * Oracle 9.0.1 or later
 170 * Microsoft SQL Server 2005 (9.00.1399)
 171
 172 == Upgrading ==
 173 1.32 has several database changes since 1.31, and will not work without schema
 174 updates. Note that due to changes to some very large tables like the revision
 175 table, the schema update may take quite long (minutes on a medium sized site,
 176 many hours on a large site).
 177
 178 Don't forget to always back up your database before upgrading!
 179
 180 See the file UPGRADE for more detailed upgrade instructions, including
 181 important information when upgrading from versions prior to 1.11.
