  45 == Compatibility ==
  46
  47 MediaWiki 1.28 requires PHP 5.5.9 or later. There is experimental support for
  48 HHVM 3.6.5 or later.
  49
  50 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  51 support for them is somewhat less mature. There is experimental support for
  52 Oracle and Microsoft SQL Server.
  53
  54 The supported versions are:
  55
  56 * MySQL 5.0.3 or later
  57 * PostgreSQL 8.3 or later
  58 * SQLite 3.3.7 or later
  59 * Oracle 9.0.1 or later
  60 * Microsoft SQL Server 2005 (9.00.1399)
  61
  62 == Upgrading ==
  63
  64 1.28 has several database changes since 1.27, and will not work without schema
  65 updates. Note that due to changes to some very large tables like the revision
  66 table, the schema update may take quite long (minutes on a medium sized site,
  67 many hours on a large site).
  68
  69 If upgrading from before 1.11, and you are using a wiki as a commons
  70 repository, make sure that it is updated as well. Otherwise, errors may arise
  71 due to database schema changes.
  72
  73 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
  74 new database fields are filled with data.
  75
  76 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
  77 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
  78 with MediaWiki 1.21.
  79
  80 Don't forget to always back up your database before upgrading!
  81
  82 See the file UPGRADE for more detailed upgrade instructions.
