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