  34 changes to languages because of Phabricator reports.

  37 * Database::getSearchEngine() (deprecated in 1.28) was removed. Use
  38   SearchEngineFactory::getSearchEngineClass() instead.
  39
  40 == Compatibility ==
  41
  42 MediaWiki 1.29 requires PHP 5.5.9 or later. There is experimental support for
  43 HHVM 3.6.5 or later.
  44
  45 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  46 support for them is somewhat less mature. There is experimental support for
  47 Oracle and Microsoft SQL Server.
  48
  49 The supported versions are:
  50
  51 * MySQL 5.0.3 or later
  52 * PostgreSQL 8.3 or later
  53 * SQLite 3.3.7 or later
  54 * Oracle 9.0.1 or later
  55 * Microsoft SQL Server 2005 (9.00.1399)
  56
  57 == Upgrading ==
  58
  59 1.29 has several database changes since 1.28, and will not work without schema
  60 updates. Note that due to changes to some very large tables like the revision
  61 table, the schema update may take quite long (minutes on a medium sized site,
  62 many hours on a large site).
  63
  64 If upgrading from before 1.11, and you are using a wiki as a commons
  65 repository, make sure that it is updated as well. Otherwise, errors may arise
  66 due to database schema changes.
  67
  68 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
  69 new database fields are filled with data.
  70
  71 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
  72 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
  73 with MediaWiki 1.21.
  74
  75 Don't forget to always back up your database before upgrading!
  76
  77 See the file UPGRADE for more detailed upgrade instructions.
