  78 == Compatibility ==
  79
  80 MediaWiki 1.20 requires PHP 5.2.3. PHP 4 is no longer supported.
  81
  82 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  83 support for them is somewhat less mature. There is experimental support for IBM
  84 DB2 and Oracle.
  85
  86 The supported versions are:
  87
  88 * MySQL 5.0.2 or later
  89 * PostgreSQL 8.3 or later
  90 * SQLite 3.3.7 or later
  91 * Oracle 9.0.1 or later
  92
  93 == Upgrading ==
  94
  95 1.20 has several database changes since 1.19, and will not work without schema
  96 updates.
  97
  98 If upgrading from before 1.11, and you are using a wiki as a commons
  99 repository, make sure that it is updated as well. Otherwise, errors may arise
 100 due to database schema changes.
 101
 102 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 103 new database fields are filled with data.
 104
 105 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 106 changes are made, and there is a slightly higher chance that things could
 107 break. Don't forget to always back up your database before upgrading!
 108
 109 See the file UPGRADE for more detailed upgrade instructions.
 110
 111 For notes on 1.19.x and older releases, see HISTORY.
