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