 100 == Compatibility ==
 101
 102 MediaWiki 1.20 requires PHP 5.2.3. PHP 4 is no longer supported.
 103
 104 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 105 support for them is somewhat less mature. There is experimental support for IBM
 106 DB2 and Oracle.
 107
 108 The supported versions are:
 109
 110 * MySQL 5.0.2 or later
 111 * PostgreSQL 8.3 or later
 112 * SQLite 3.3.7 or later
 113 * Oracle 9.0.1 or later
 114
 115 == Upgrading ==
 116
 117 1.20 has several database changes since 1.19, and will not work without schema
 118 updates.
 119
 120 If upgrading from before 1.11, and you are using a wiki as a commons
 121 repository, make sure that it is updated as well. Otherwise, errors may arise
 122 due to database schema changes.
 123
 124 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 125 new database fields are filled with data.
 126
 127 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 128 changes are made, and there is a slightly higher chance that things could
 129 break. Don't forget to always back up your database before upgrading!
 130
 131 See the file UPGRADE for more detailed upgrade instructions.
 132
 133 For notes on 1.19.x and older releases, see HISTORY.
