== MediaWiki 1.30 ==

THIS IS NOT A RELEASE YET

MediaWiki 1.30 is an alpha-quality branch and is not recommended for use in
production.

=== Configuration changes in 1.30 ===
* The C.UTF-8 locale should be used for $wgShellLocale, if available, to avoid
  unexpected behavior when things use local-sensitive string comparisons. For
  example, Scribunto considers "bar" < "Foo" in most locales since it ignores
  case.
* $wgShellLocale now affects LC_ALL rather than only LC_CTYPE. See
  documentation of $wgShellLocale for details.
* $wgJobClasses may now specify callback functions
  as an alternative to plain class names.
  This is intended for extensions that want control
  over the instantiation of their jobs,
  to allow for proper dependency injection.

=== New features in 1.30 ===
* (T37247) Output from Parser::parse() will now be wrapped in a div with
  class="mw-parser-output" by default. This may be changed or disabled using
  ParserOptions::setWrapOutputClass().
* Added 'ChangeTagsAllowedAdd' hook, enabling extensions to allow software-
  specific tags to be added by users.
* File storage backends that supports headers (eg. Swift) now store an
  X-Content-Dimensions header for originals that contain the media's dimensions
  as page ranges keyed by dimensions.

=== External library changes in 1.30 ===

=== Bug fixes in 1.30 ===
* (T151633) Ordered list items use now Devanagari digits in Nepalese
  (thanks to Sfic)

=== Action API changes in 1.30 ===
* (T37247) action=parse output will be wrapped in a div with
  class="mw-parser-output" by default. This may be changed or disabled using
  the new 'wrapoutputclass' parameter.
* When errorformat is not 'bc', abort reasons from action=login will be
  formatted as specified by the error formatter parameters.

=== Action API internal changes in 1.30 ===
* …

=== Languages updated in 1.30 ===
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.

* …

=== Other changes in 1.30 ===
* The use of an associative array for $wgProxyList, where the IP address is in
  the key instead of the value, is deprecated (e.g. [ '127.0.0.1' => 'value' ]).
  Please convert these arrays to indexed/sequential ones (e.g. [ '127.0.0.1' ]).
* mw.user.bucket (deprecated in 1.23) was removed.
* LoadBalancer::getServerInfo() and LoadBalancer::setServerInfo() are
  deprecated. There are no known callers.
* File::getStreamHeaders() was deprecated.
* MediaHandler::getStreamHeaders() was deprecated.
* The ExtractThumbParameters hook (deprecated in 1.21) was removed.
* The OutputPage::addParserOutputNoText and ::getHeadLinks methods (both
  deprecated in 1.24) were removed.

== Compatibility ==
MediaWiki 1.30 requires PHP 5.5.9 or later. There is experimental support for
HHVM 3.6.5 or later.

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 5.0.3 or later
* PostgreSQL 8.3 or later
* SQLite 3.3.7 or later
* Oracle 9.0.1 or later
* Microsoft SQL Server 2005 (9.00.1399)

== Upgrading ==
1.30 has several database changes since 1.29, 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 1.29.x and older releases, see HISTORY.

== Online documentation ==

== 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.
