48 * Oracle 9.0.1 or later

50 == Upgrading ==
51
52 1.21 has several database changes since 1.20, and will not work without schema
53 updates.
54
55 If upgrading from before 1.11, and you are using a wiki as a commons
56 repository, make sure that it is updated as well. Otherwise, errors may arise
57 due to database schema changes.
58
59 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
60 new database fields are filled with data.
61
62 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
63 changes are made, and there is a slightly higher chance that things could
64 break. Don't forget to always back up your database before upgrading!
65
66 See the file UPGRADE for more detailed upgrade instructions.
67
68 For notes on 1.19.x and older releases, see HISTORY.
