Security reminder: MediaWiki does not require PHP's register_globals. If you
have it on, turn it '''off''' if you can.

== MediaWiki 1.22 ==

THIS IS NOT A RELEASE YET

MediaWiki 1.22 is an alpha-quality branch and is not recommended for use in
production.

=== Configuration changes in 1.22 ===
* $wgRedirectScript was removed. It was unused.

=== New features in 1.22 ===

=== Bug fixes in 1.22 ===

=== API changes in 1.22 ===

=== Languages updated in 1.22===

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 Bugzilla reports.

=== Other changes in 1.22 ===
* redirect.php was removed. It was unused.
* ClickTracking integration was dropped from the mediaWiki.user.bucket
  JavaScript function. The 'tracked' option is now ignored.
* BREAKING CHANGE: Legacy skins Simple, MySkin and Standard were all removed.
  Nostalgia was moved to an extension.
* Event namespace used by jquery.makeCollapsible has been changed from
  'mw-collapse' to 'mw-collapsible' for consistency with the module name.
* BREAKING CHANGE: The "ExternalAuth" authentication subsystem was removed, along
  with its associated globals of $wgExternalAuthType, $wgExternalAuthConf,
  $wgAutocreatePolicy and $wgAllowPrefChange. Affected users are encouraged to
  use AuthPlugin for external authentication/authorization needs.

== Compatibility ==

MediaWiki 1.22 requires PHP 5.3.2 or later.

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
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 ==

1.22 has several database changes since 1.21, 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).

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, you should upgrade to
1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
with MediaWiki 1.21.

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

See the file UPGRADE for more detailed upgrade instructions.

For notes on 1.21.x and older releases, see HISTORY.
