== MediaWiki 1.19 ==

THIS IS NOT A RELEASE YET

MediaWiki 1.19 is an alpha-quality branch and is not recommended for use in
production.

=== Configuration changes in 1.19 ===
* Changed LoginAuthenticateAudit hook so that it may be called before a
  valid user is available.  In those cases, an anonymouse user object
  will be supplied.
* Removed SkinTemplateSetupPageCss hook; use BeforePageDisplay instead.
* (bug 27132) movefile right granted by default to registered users.
* Default cookie lifetime ($wgCookieExpiration) is increased to 180 days.
* (bug 31204) Removed old user.user_options.
* $wgMaxImageArea now applies to jpeg files if they are not scaled with
  ImageMagick.
* Introduced $wgQueryPageDefaultLimit (defaults to 50) for the number of
  items to show by default on query pages (special pages such as Whatlinkshere).
* (bug 32470) Increase the length of ug_group.
* (bug 32239) Removed wgEnableTooltipsAndAccesskeys.
* Removed $wgVectorShowVariantName.
* Removed $wgExtensionAliasesFiles. Use wgExtensionMessagesFiles.

=== New features in 1.19 ===

  cache is used.
* $wgDnsBlacklistUrls now accepts an array with url and key as the
  elements to work with DNSBLs that require keys, such as
  Project Honeypot.
* (bug 30022) Add support for custom loadScript sources to ResourceLoader.

  $wgCleanupPresentationalAttributes.
* Magic words (time and number-formatting ones, plus DIRECTIONMARK, but not
  NAMESPACE) now depend on the page content language instead of the site

  localisation.

  instead of the wiki content language.

  of generic styles from MonoBook or Vector's css.

  syntax.

  'chick' and 'monobook').
* The constructor for CategoryView has changed, the second parameter is now a
  Context source and is required.

  proper html building methods to escape the normal get{...}URL methods instead.
* The $variant arguments in the Title::get{Local,Full,Link,Canonical}URL methods
  have been replaced with a secondary query argument.

  methods have been removed, the variant is now part of the $query argument.

  using Title::isCssJsSubpage() or checking Title::isWrongCaseCssJsPage().

== Compatibility ==

MediaWiki 1.19 requires PHP 5.2.3. PHP 4 is no longer supported.

MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
support for them is somewhat less mature. There is experimental support for IBM
DB2 and Oracle.

The supported versions are:

* MySQL 5.0.2 or later
* PostgreSQL 8.3 or later
* SQLite 3.3.7 or later
* Oracle 9.0.1 or later

== Upgrading ==

1.19 has several database changes since 1.18, and will not work without schema
updates.

As of 1.19 several JavaScript interfaces that were deprecated or superseeded in
MediaWiki 1.17, MediaWiki 1.16 or even earlier have been removed. They are
listed at the top of the "Other changes" list as a "BREAKING CHANGE".

If upgrading from before 1.11, and you are using a wiki as a commons
repository, make sure that it is updated as well. Otherwise, errors may arise
due to database schema changes.

If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
new database fields are filled with data.

If you are upgrading from MediaWiki 1.4.x or earlier, some major database
changes are made, and there is a slightly higher chance that things could
break. Don't forget to always back up your database before upgrading!

See the file UPGRADE for more detailed upgrade instructions.

For notes on 1.18.x and older releases, see HISTORY.

MediaWiki.org, and is covered under the GNU Free Documentation License (except
for pages that explicitly state that their contents are in the public domain):

== Mailing list ==

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

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

        http://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.
