== MediaWiki 1.32 ==

THIS IS NOT A RELEASE YET

MediaWiki 1.32 is an alpha-quality branch and is not recommended for use in
production.

=== Configuration changes in 1.32 ===
* (T115414) The $wgEnableAPI and $wgEnableWriteAPI settings, deprecated in 1.31,
  have been removed.
* The $wgUseAjax setting, deprecated in 1.31, is now ignored.
* The $wgSiteSupportPage setting, unused since 1.5, was removed.
* The default quality of JPEG thumbnails generated by GD was reduced from 95 to
  80. The quality of JPEG thumbnails is now configurable through the new setting
  $wgJpegQuality (default 80). This aligns the quality to what ImageMagick uses.
* $wgExperimentalHtmlIds, deprecated since 1.30, has been removed. The
  'html5-legacy' value for $wgFragmentMode is no longer accepted.
* The experimental Html5Internal and Html5Depurate tidy drivers were removed.
  RemexHtml, which is the default, should be used instead.
* (T135963) You can now define a Content Security Policy for your wiki. This
  adds a defense-in-depth feature to stop an attacker who has found a bug in
  the parser allowing them to insert malicious attributes. Disabled by default,
  you can configure this via $wgCSPHeader and $wgCSPReportOnlyHeader.

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

=== Bug fixes in 1.32 ===
* …

=== Action API changes in 1.32 ===
* Added templated parameters.
  * A module can define a templated parameter like "{fruit}-quantity", where
    the actual parameters recognized correspond to the values of a multi-valued
    parameter. Then clients can make requests like
    "fruits=apples|bananas&apples-quantity=1&bananas-quantity=5".
  * action=paraminfo will return templated parameter definitions separately
    from normal parameters. All parameter definitions now include an "index"
    key to allow clients to maintain parameter ordering when merging normal and
    templated parameters.

=== Action API internal changes in 1.32 ===
* Added 'ApiParseMakeOutputPage' hook.
* Parameter names may no longer contain '{' or '}', as these are now used for
  templated parameters.

=== Languages updated in 1.32 ===
MediaWiki supports over 350 languages. Many localisations are updated regularly.
Below only new and removed languages are listed, as well as changes to languages
because of Phabricator reports.

* (T193566) Added language support for Ambonese Malay (abs).

=== Breaking changes in 1.32 ===
* $wgRequestTime, deprecated in 1.25, was removed. Use
  $_SERVER['REQUEST_TIME_FLOAT'] or WebRequest::getElapsedTime() instead.
* The MediaWikiI18N class, deprecated in 1.31, was removed.
* QuickTemplate::setTranslator(), deprecated in 1.31, was removed. Use
  Skin::msg() instead.
* wfInitShellLocale(), deprecated in 1.30, was removed.
* wfShellExecDisabled(), deprecated in 1.30, was removed.
* The type string for the parameter $lang of DateFormatter::getInstance,
  deprecated in 1.31, was removed.
* The EDIT_TOKEN_SUFFIX constant deprecated in 1.27, was removed. Use
  MediaWiki\Session\Token::SUFFIX instead.
* EditPage::isOouiEnabled() deprecated in 1.30, was removed.
* mw.util.wikiGetlink(), deprecated in 1.23, was removed. Use mw.util.getUrl()
  instead.
* (T61113) The following methods and constants from the Revision class, which
  were deprecated in 1.25, have now been removed:
  * Revision::getRawUser()
  * Revision::getRawUserText()
  * Revision::getRawComment()
* window.gM() from mediawiki.jqueryMsg, deprecated in 1.23, was removed. Use
  mw.msg() or mw.message() instead.
* mw.util.escapeId(), deprecated in 1.30, was removed. Use
  mw.util.escapeIdForAttribute or mw.util.escapeIdForLink instead.
* mw.util.updateTooltipAccessKeys(), deprecated in 1.24, was removed. Use
  jquery.accessKeyLabel instead.
* The SqlDataUpdate class, deprecated in 1.28, has been removed.
* The Html5Internal and Html5Depurate tidy driver classes were removed, along with the
  Balancer tidy implementation. Both implementations were experimental, and were replaced
  by RemexHtml.

=== Deprecations in 1.32 ===
* Use of a StartProfiler.php file is deprecated in favour of placing
  configuration in LocalSettings.php.
* HTMLForm::setSubmitProgressive() is deprecated. No need to call it. Submit
  button is already marked as progressive.
* Skin::setupSkinUserCss() is deprecated. Adding of modules to load
  has been centralised to Skin::getDefaultModules(), which is now capable
  of queueing style modules as well.
* OutputPage::addModuleScripts() and ParserOutput::addModuleScripts are
  deprecated. Use addModules() instead.
* Overriding SearchEngine::{searchText,searchTitle,searchArchiveTitle}
  in extending classes is deprecated.  Extend related doSearch* methods
  instead.
* CollationFa has been removed completely as it's not needed anymore

=== Other changes in 1.32 ===
* Soft hyphens (U+00AD) are now automatically removed from titles; these
  characters can accidentally end up in copy-and-pasted titles.
* Strip Unicode 6.3.0 directional formatting characters (U+061C, U+2066,
  U+2067, U+2068, U+2069) from the title.
* …

== Compatibility ==
MediaWiki 1.32 requires PHP 5.5.9 or later. Although HHVM 3.18.5 or later is
supported, it is generally advised to use PHP 5.5.9 or later for long term
support.

MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
but support for them is somewhat less mature. There is experimental support for
Oracle and Microsoft SQL Server.

The supported versions are:

* MySQL 5.5.8 or later
* PostgreSQL 9.2 or later
* SQLite 3.3.7 or later
* Oracle 9.0.1 or later
* Microsoft SQL Server 2005 (9.00.1399)

== Upgrading ==
1.32 has several database changes since 1.31, and will not work without schema
updates. Note that due to changes to some very large tables like the revision
table, the schema update may take quite long (minutes on a medium sized site,
many hours on a large site).

Don't forget to always back up your database before upgrading!

See the file UPGRADE for more detailed upgrade instructions, including
important information when upgrading from versions prior to 1.11.

For notes on 1.31.x and older releases, see HISTORY.

MediaWiki.org, and is covered under the GNU Free Documentation License (except

== Mailing list ==
A mailing list is available for MediaWiki user support and discussion:

       https://lists.wikimedia.org/mailman/listinfo/mediawiki-l

A low-traffic announcements-only list is also available:

       https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce

It's highly recommended that you sign up for one of these lists if you're
going to run a public MediaWiki, so you can be notified of security fixes.

== IRC help ==
There's usually someone online in #mediawiki on irc.freenode.net.
