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