 155

 161
 162 * MySQL 5.0.3 or later
 163 * PostgreSQL 8.3 or later

 166 * Microsoft SQL Server 2005 (9.00.1399)
 167
 168 == Upgrading ==
 169 1.31 has several database changes since 1.30, and will not work without schema
 170 updates. Note that due to changes to some very large tables like the revision
 171 table, the schema update may take quite long (minutes on a medium sized site,
 172 many hours on a large site).
 173
 174 Don't forget to always back up your database before upgrading!
 175
 176 See the file UPGRADE for more detailed upgrade instructions, including
 177 important information when upgrading from versions prior to 1.11.
