 * The maintenance script populateSha1.php was renamed to the more concise populateImageSha1.php.
 * The Client-IP header is no longer checked for when trying to resolve a client's real IP address.
 * (bug 22096) Although IE5.x and below was already unsupported officially, stylesheets existing exclusively for IE5.0 and IE5.5 have now been removed (which were in skins 'chick' and 'monobook').
 * The constructor for CategoryView has changed, the second parameter is now a Context source and is required.
 * The Title::escape{Local,Full,Canonical}URL methods are deprecated, please use 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.
 * The $variant argument in the hooks for the Title::get{Local,Full,Link,Canonical}URL methods have been removed, the variant is now part of the $query argument.

New configuration variable $wgPreloadJavaScriptMwUtil has been introduced for this (set to false by default for new installations). Set to true if your wiki has a large amount of user/site scripts that are lacking dependency information. In the short to medium term these user/site scripts should be fixed by adding the used modules to the dependencies in the module registry and/or wrapping them in a callback to mw.loader.using.
 * MediaWiki now requires MySQL 5.0.2 or later when using a MySQL database.

互換性
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 以降
 * PostgreSQL 8.3 以降
 * SQLite 3.3.7 以降
 * Oracle 9.0.1 以降

アップグレード
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 superseded 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.

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.
