-== Compatibility ==
-
-MediaWiki 1.25 requires PHP 5.3.3 or later. There is experimental support for
-HHVM 3.3.0.
-
-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 and Microsoft SQL Server.
+== MediaWiki 1.24.6 ==
-The supported versions are:
+This is a maintenance release of the MediaWiki 1.24 branch.
-* 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 ==
-
-1.25 has several database changes since 1.24, 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 1.24.x and older releases, see HISTORY.
