 132
 133 == Compatibility ==
 134
 135 MediaWiki 1.20 requires PHP 5.3.2. PHP 4 is no longer supported.
 136
 137 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 138 support for them is somewhat less mature. There is experimental support for IBM
 139 DB2 and Oracle.
 140
 141 The supported versions are:
 142
 143 * MySQL 5.0.2 or later
 144 * PostgreSQL 8.3 or later
 145 * SQLite 3.3.7 or later
 146 * Oracle 9.0.1 or later
 147
 148 == Upgrading ==
 149
 150 1.20 has several database changes since 1.19, and will not work without schema
 151 updates.
 152
 153 If upgrading from before 1.11, and you are using a wiki as a commons
 154 repository, make sure that it is updated as well. Otherwise, errors may arise
 155 due to database schema changes.
 156
 157 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 158 new database fields are filled with data.
 159
 160 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 161 changes are made, and there is a slightly higher chance that things could
 162 break. Don't forget to always back up your database before upgrading!
 163
 164 See the file UPGRADE for more detailed upgrade instructions.
 165
 166 For notes on 1.19.x and older releases, see HISTORY.
