 114 The supported versions are:
 115
 116 * MySQL 5.0.3 or later
 117 * PostgreSQL 8.3 or later

 119 * Oracle 9.0.1 or later
 120 * Microsoft SQL Server 2005 (9.00.1399)
 121
 122 == Upgrading ==
 123 1.31 has several database changes since 1.30, and will not work without schema
 124 updates. Note that due to changes to some very large tables like the revision
 125 table, the schema update may take quite long (minutes on a medium sized site,
 126 many hours on a large site).
 127
 128 Don't forget to always back up your database before upgrading!
 129
 130 See the file UPGRADE for more detailed upgrade instructions, including
 131 important information when upgrading from versions prior to 1.11.
