  99 == Compatibility ==
 100 MediaWiki 1.31 requires PHP 5.5.9 or later. There is experimental support for
 101 HHVM 3.6.5 or later.
 102
 103 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 104 but support for them is somewhat less mature. There is experimental support for
 105 Oracle and Microsoft SQL Server.
 106
 107 The supported versions are:
 108
 109 * MySQL 5.0.3 or later
 110 * PostgreSQL 8.3 or later
 111 * SQLite 3.3.7 or later
 112 * Oracle 9.0.1 or later
 113 * Microsoft SQL Server 2005 (9.00.1399)
 114
 115 == Upgrading ==
 116 1.31 has several database changes since 1.30, and will not work without schema
 117 updates. Note that due to changes to some very large tables like the revision
 118 table, the schema update may take quite long (minutes on a medium sized site,
 119 many hours on a large site).
 120
 121 Don't forget to always back up your database before upgrading!
 122
 123 See the file UPGRADE for more detailed upgrade instructions, including
 124 important information when upgrading from versions prior to 1.11.
