  90 == Compatibility ==
  91 MediaWiki 1.31 requires PHP 5.5.9 or later. There is experimental support for
  92 HHVM 3.6.5 or later.
  93
  94 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
  95 but support for them is somewhat less mature. There is experimental support for
  96 Oracle and Microsoft SQL Server.
  97
  98 The supported versions are:
  99
 100 * MySQL 5.0.3 or later
 101 * PostgreSQL 8.3 or later

 103 * Oracle 9.0.1 or later
 104 * Microsoft SQL Server 2005 (9.00.1399)
 105
 106 == Upgrading ==
 107 1.31 has several database changes since 1.30, and will not work without schema
 108 updates. Note that due to changes to some very large tables like the revision
 109 table, the schema update may take quite long (minutes on a medium sized site,
 110 many hours on a large site).
 111
 112 Don't forget to always back up your database before upgrading!
 113
 114 See the file UPGRADE for more detailed upgrade instructions, including
 115 important information when upgrading from versions prior to 1.11.
