45
46 The supported versions are:
47
48 * MySQL 5.0.2 or later
49 * PostgreSQL 8.3 or later
50 * SQLite 3.3.7 or later
51 * Oracle 9.0.1 or later
52
53 == Upgrading ==
54
55 1.21 has several database changes since 1.20, and will not work without schema
56 updates.
57
58 If upgrading from before 1.11, and you are using a wiki as a commons
59 repository, make sure that it is updated as well. Otherwise, errors may arise
60 due to database schema changes.
61
62 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
63 new database fields are filled with data.
64
65 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
66 changes are made, and there is a slightly higher chance that things could
67 break. Don't forget to always back up your database before upgrading!
68
69 See the file UPGRADE for more detailed upgrade instructions.
