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