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
  45 === External library changes in 1.32 ===
  46 * …
  47
  48 ==== Upgraded external libraries ====
  49 * Updated QUnit from 2.4.0 to 2.6.0.
  50 * Updated wikimedia/scoped-callback from 1.0.0 to 2.0.0.
  51 ** ScopedCallback objects can no longer be serialized.
  52
  53 ==== New external libraries ====
  54 * Added wikimedia/xmp-reader 0.5.1
  55 * …
  56
  57 ==== Removed and replaced external libraries ====
  58 * …
  59
  60 === Bug fixes in 1.32 ===
  61 * SpecialPage::execute() will now only call checkLoginSecurityLevel() if
  62   getLoginSecurityLevel() returns non-false.
  63
  64 === Action API changes in 1.32 ===
  65 * Added templated parameters.
  66   * A module can define a templated parameter like "{fruit}-quantity", where
  67     the actual parameters recognized correspond to the values of a multi-valued
  68     parameter. Then clients can make requests like
  69     "fruits=apples|bananas&apples-quantity=1&bananas-quantity=5".
  70   * action=paraminfo will return templated parameter definitions separately
  71     from normal parameters. All parameter definitions now include an "index"
  72     key to allow clients to maintain parameter ordering when merging normal and
  73     templated parameters.
  74 * It is now an error to submit too many values for a multi-valued parameter.
  75   This has generated a warning since MediaWiki 1.14.
  76
  77 === Action API internal changes in 1.32 ===
  78 * Added 'ApiParseMakeOutputPage' hook.
  79 * Parameter names may no longer contain '{' or '}', as these are now used for
  80   templated parameters.
  81 * (T194950) Added 'ApiMaxLagInfo' hook.
  82
  83 === Languages updated in 1.32 ===
  84 MediaWiki supports over 350 languages. Many localisations are updated regularly.
  85 Below only new and removed languages are listed, as well as changes to languages
  86 because of Phabricator reports.
  87
  88 * (T193566) Added language support for Ambonese Malay (abs).
  89 * (T194047) Added language support for Shawiya, Latin script (shy-latn).
  90 * (T195940) Added language support for Batak Mandailing (btm).

 154 * Use of a StartProfiler.php file is deprecated in favour of placing

 157   button is already marked as progressive.

 159   has been centralised to Skin::getDefaultModules(), which is now capable
 160   of queueing style modules as well.
 161 * OutputPage::addModuleScripts() and ParserOutput::addModuleScripts are
 162   deprecated. Use addModules() instead.
 163 * Overriding SearchEngine::{searchText,searchTitle,searchArchiveTitle}

 165   instead.
 166 * CollationFa has been removed completely as it's not needed anymore

 172 * ApiBase::truncateArray() is deprecated. No replacement, as nothing is known
 173   to use it.
 174 * WatchAction::getUnwatchToken is deprecated. Use WatchAction::getWatchToken
 175   with the 'unwatch' action parameter instead.

 177   constant INTL_ICU_VERSION directly in all versions that MediaWiki supports.

 179 * The ApiQueryContributions class has been renamed to ApiQueryUserContribs.

 182
 183 === Other changes in 1.32 ===
 184 * …
 185
 186 == Compatibility ==
 187 MediaWiki 1.32 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
 188 supported, it is generally advised to use PHP 7.0.0 or later for long term
 189 support.
 190
 191 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 192 but support for them is somewhat less mature. There is experimental support for
 193 Oracle and Microsoft SQL Server.
 194
 195 The supported versions are:
 196
 197 * MySQL 5.5.8 or later
 198 * PostgreSQL 9.2 or later
 199 * SQLite 3.3.7 or later
 200 * Oracle 9.0.1 or later
 201 * Microsoft SQL Server 2005 (9.00.1399)
 202
 203 == Upgrading ==
 204 1.32 has several database changes since 1.31, and will not work without schema
 205 updates. Note that due to changes to some very large tables like the revision
 206 table, the schema update may take quite long (minutes on a medium sized site,
 207 many hours on a large site).
 208
 209 Don't forget to always back up your database before upgrading!
 210
 211 See the file UPGRADE for more detailed upgrade instructions, including
 212 important information when upgrading from versions prior to 1.11.
