  71
  72 == Compatibility ==
  73
  74 MediaWiki 1.20 requires PHP 5.2.3. PHP 4 is no longer supported.
  75
  76 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  77 support for them is somewhat less mature. There is experimental support for IBM
  78 DB2 and Oracle.
  79
  80 The supported versions are:
  81
  82 * MySQL 5.0.2 or later
  83 * PostgreSQL 8.3 or later
  84 * SQLite 3.3.7 or later
  85 * Oracle 9.0.1 or later
  86
  87 == Upgrading ==
  88
  89 1.20 has several database changes since 1.19, and will not work without schema
  90 updates.
  91
  92 If upgrading from before 1.11, and you are using a wiki as a commons
  93 repository, make sure that it is updated as well. Otherwise, errors may arise
  94 due to database schema changes.
  95
  96 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
  97 new database fields are filled with data.
  98
  99 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 100 changes are made, and there is a slightly higher chance that things could
 101 break. Don't forget to always back up your database before upgrading!
 102
 103 See the file UPGRADE for more detailed upgrade instructions.
 104
 105 For notes on 1.19.x and older releases, see HISTORY.
