  57 == Compatibility ==
  58 MediaWiki 1.31 requires PHP 5.5.9 or later. There is experimental support for
  59 HHVM 3.6.5 or later.
  60
  61 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
  62 but support for them is somewhat less mature. There is experimental support for
  63 Oracle and Microsoft SQL Server.
  64
  65 The supported versions are:
  66
  67 * MySQL 5.0.3 or later
  68 * PostgreSQL 8.3 or later
  69 * SQLite 3.3.7 or later
  70 * Oracle 9.0.1 or later
  71 * Microsoft SQL Server 2005 (9.00.1399)
  72
  73 == Upgrading ==
  74 1.31 has several database changes since 1.30, and will not work without schema
  75 updates. Note that due to changes to some very large tables like the revision
  76 table, the schema update may take quite long (minutes on a medium sized site,
  77 many hours on a large site).
  78
  79 Don't forget to always back up your database before upgrading!
  80
  81 See the file UPGRADE for more detailed upgrade instructions, including
  82 important information when upgrading from versions prior to 1.11.
