 112
 113 == Compatibility ==
 114
 115 MediaWiki 1.20 requires PHP 5.2.3. PHP 4 is no longer supported.
 116
 117 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 118 support for them is somewhat less mature. There is experimental support for IBM
 119 DB2 and Oracle.
 120
 121 The supported versions are:
 122
 123 * MySQL 5.0.2 or later
 124 * PostgreSQL 8.3 or later
 125 * SQLite 3.3.7 or later
 126 * Oracle 9.0.1 or later
 127
 128 == Upgrading ==
 129
 130 1.20 has several database changes since 1.19, and will not work without schema
 131 updates.
 132
 133 If upgrading from before 1.11, and you are using a wiki as a commons
 134 repository, make sure that it is updated as well. Otherwise, errors may arise
 135 due to database schema changes.
 136
 137 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 138 new database fields are filled with data.
 139
 140 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 141 changes are made, and there is a slightly higher chance that things could
 142 break. Don't forget to always back up your database before upgrading!
 143
 144 See the file UPGRADE for more detailed upgrade instructions.
 145
 146 For notes on 1.19.x and older releases, see HISTORY.
 147
 148 == Online documentation ==

 151 MediaWiki.org, and is covered under the GNU Free Documentation License (except
