  33 == Compatibility ==
  34
  35 MediaWiki 1.27 requires PHP 5.3.3 or later. There is experimental support for
  36 HHVM 3.3.0.
  37
  38 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  39 support for them is somewhat less mature. There is experimental support for
  40 Oracle and Microsoft SQL Server.
  41
  42 The supported versions are:
  43
  44 * MySQL 5.0.3 or later
  45 * PostgreSQL 8.3 or later
  46 * SQLite 3.3.7 or later
  47 * Oracle 9.0.1 or later
  48 * Microsoft SQL Server 2005 (9.00.1399)

  50 == Upgrading ==
  51
  52 1.27 has several database changes since 1.26, and will not work without schema
  53 updates. Note that due to changes to some very large tables like the revision
  54 table, the schema update may take quite long (minutes on a medium sized site,
  55 many hours on a large site).
  56
  57 If upgrading from before 1.11, and you are using a wiki as a commons
  58 repository, make sure that it is updated as well. Otherwise, errors may arise
  59 due to database schema changes.
  60
  61 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
  62 new database fields are filled with data.
  63
  64 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
  65 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
  66 with MediaWiki 1.21.
  67
  68 Don't forget to always back up your database before upgrading!
  69
  70 See the file UPGRADE for more detailed upgrade instructions.
