  49 === Other changes in 1.21 ===
  50
  51 == Compatibility ==
  52
  53 MediaWiki 1.21 requires PHP 5.3.2 or later.
  54
  55 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  56 support for them is somewhat less mature. There is experimental support for IBM
  57 DB2 and Oracle.
  58
  59 The supported versions are:
  60
  61 * MySQL 5.0.2 or later
  62 * PostgreSQL 8.3 or later
  63 * SQLite 3.3.7 or later
  64 * Oracle 9.0.1 or later
  65
  66 == Upgrading ==
  67
  68 1.21 has several database changes since 1.20, and will not work without schema
  69 updates. Note that due to changes to some very large tables like the revision
  70 table, the schema update may take quite long (minutes on a medium sized site,
  71 many hours on a large site).
  72
  73 If upgrading from before 1.11, and you are using a wiki as a commons
  74 repository, make sure that it is updated as well. Otherwise, errors may arise
  75 due to database schema changes.
  76
  77 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
  78 new database fields are filled with data.
  79
  80 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
  81 changes are made, and there is a slightly higher chance that things could
  82 break. Don't forget to always back up your database before upgrading!
  83
  84 See the file UPGRADE for more detailed upgrade instructions.
  85
  86 For notes on 1.19.x and older releases, see HISTORY.
