  69 MediaWiki 1.31 requires PHP 5.5.9 or later. There is experimental support for
  70 HHVM 3.6.5 or later.
  71
  72 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
  73 but support for them is somewhat less mature. There is experimental support for
  74 Oracle and Microsoft SQL Server.
  75
  76 The supported versions are:
  77
  78 * MySQL 5.0.3 or later
  79 * PostgreSQL 8.3 or later
  80 * SQLite 3.3.7 or later
  81 * Oracle 9.0.1 or later
  82 * Microsoft SQL Server 2005 (9.00.1399)
  83
  84 == Upgrading ==
  85 1.31 has several database changes since 1.30, and will not work without schema
  86 updates. Note that due to changes to some very large tables like the revision
  87 table, the schema update may take quite long (minutes on a medium sized site,
  88 many hours on a large site).
  89
  90 Don't forget to always back up your database before upgrading!
  91
  92 See the file UPGRADE for more detailed upgrade instructions, including
  93 important information when upgrading from versions prior to 1.11.
