58 * Oracle 9.0.1 or later

60 == Upgrading ==
61
62 1.21 has several database changes since 1.20, and will not work without schema
63 updates. Note that due to changes to some very large tables like the revision
64 table, the schema update may take quite long (minutes on a medium sized site,
65 many hours on a large site).
66
67 If upgrading from before 1.11, and you are using a wiki as a commons
68 repository, make sure that it is updated as well. Otherwise, errors may arise
69 due to database schema changes.
70
71 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
72 new database fields are filled with data.
73
74 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
75 changes are made, and there is a slightly higher chance that things could
76 break. Don't forget to always back up your database before upgrading!
77
78 See the file UPGRADE for more detailed upgrade instructions.
79
80 For notes on 1.19.x and older releases, see HISTORY.
