  39 === Other changes in 1.21 ===
  40
  41 == Compatibility ==
  42
  43 MediaWiki 1.21 requires PHP 5.3.2 or later.
  44
  45 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  46 support for them is somewhat less mature. There is experimental support for IBM
  47 DB2 and Oracle.
  48
  49 The supported versions are:
  50
  51 * MySQL 5.0.2 or later
  52 * PostgreSQL 8.3 or later
  53 * SQLite 3.3.7 or later
  54 * Oracle 9.0.1 or later
  55
  56 == Upgrading ==
  57
  58 1.21 has several database changes since 1.20, and will not work without schema
  59 updates.
  60
  61 If upgrading from before 1.11, and you are using a wiki as a commons
  62 repository, make sure that it is updated as well. Otherwise, errors may arise
  63 due to database schema changes.
  64
  65 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
  66 new database fields are filled with data.
  67
  68 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
  69 changes are made, and there is a slightly higher chance that things could
  70 break. Don't forget to always back up your database before upgrading!
  71
  72 See the file UPGRADE for more detailed upgrade instructions.
  73
  74 For notes on 1.19.x and older releases, see HISTORY.
