76
77 == Compatibility ==
78
79 MediaWiki 1.20 requires PHP 5.2.3. PHP 4 is no longer supported.
80
81 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
82 support for them is somewhat less mature. There is experimental support for IBM
83 DB2 and Oracle.
84
85 The supported versions are:
86
87 * MySQL 5.0.2 or later
88 * PostgreSQL 8.3 or later
89 * SQLite 3.3.7 or later
90 * Oracle 9.0.1 or later
91
92 == Upgrading ==
93
94 1.20 has several database changes since 1.19, and will not work without schema
95 updates.
96
97 If upgrading from before 1.11, and you are using a wiki as a commons
98 repository, make sure that it is updated as well. Otherwise, errors may arise
99 due to database schema changes.
100
101 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
102 new database fields are filled with data.
103
104 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
105 changes are made, and there is a slightly higher chance that things could
106 break. Don't forget to always back up your database before upgrading!
107
108 See the file UPGRADE for more detailed upgrade instructions.
109
110 For notes on 1.19.x and older releases, see HISTORY.
