 105 HHVM 3.6.5 or later.
 106
 107 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 108 but support for them is somewhat less mature. There is experimental support for
 109 Oracle and Microsoft SQL Server.
 110
 111 The supported versions are:
 112
 113 * MySQL 5.0.3 or later
 114 * PostgreSQL 8.3 or later
 115 * SQLite 3.3.7 or later
 116 * Oracle 9.0.1 or later
 117 * Microsoft SQL Server 2005 (9.00.1399)
 118
 119 == Upgrading ==
 120 1.31 has several database changes since 1.30, and will not work without schema
 121 updates. Note that due to changes to some very large tables like the revision
 122 table, the schema update may take quite long (minutes on a medium sized site,
 123 many hours on a large site).
 124
 125 Don't forget to always back up your database before upgrading!
 126
 127 See the file UPGRADE for more detailed upgrade instructions, including
 128 important information when upgrading from versions prior to 1.11.
