 103
 104 == Compatibility ==
 105
 106 MediaWiki 1.20 requires PHP 5.2.3. PHP 4 is no longer supported.
 107
 108 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 109 support for them is somewhat less mature. There is experimental support for IBM
 110 DB2 and Oracle.
 111
 112 The supported versions are:
 113
 114 * MySQL 5.0.2 or later
 115 * PostgreSQL 8.3 or later
 116 * SQLite 3.3.7 or later
 117 * Oracle 9.0.1 or later
 118
 119 == Upgrading ==
 120
 121 1.20 has several database changes since 1.19, and will not work without schema
 122 updates.
 123
 124 If upgrading from before 1.11, and you are using a wiki as a commons
 125 repository, make sure that it is updated as well. Otherwise, errors may arise
 126 due to database schema changes.
 127
 128 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 129 new database fields are filled with data.
 130
 131 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 132 changes are made, and there is a slightly higher chance that things could
 133 break. Don't forget to always back up your database before upgrading!
 134
 135 See the file UPGRADE for more detailed upgrade instructions.
 136
 137 For notes on 1.19.x and older releases, see HISTORY.
 138
 139 == Online documentation ==

 141 Documentation for both end-users and site administrators is available on
 142 MediaWiki.org, and is covered under the GNU Free Documentation License (except
