   3 THIS IS NOT A RELEASE YET
   4
   5 MediaWiki 1.29 is an alpha-quality branch and is not recommended for use in
   6 production.
   7
   8 === Configuration changes in 1.29 ===
   9 * Default cookie expiration time has been reduced to 30 days. Login cookie expiration time is
  10   kept at 180 days.
  11 * A new configuration variable has been added: $wgCookieSetOnAutoblock. This
  12   determines whether to set a cookie when a user is autoblocked. Doing so means
  13   that a blocked user, even after logging out and moving to a new IP address,
  14   will still be blocked.
  15 * The resetpassword right and associated password reset capture feature has
  16   been removed.
  17
  18 === New features in 1.29 ===
  19 * (T5233) A cookie can now be set when a user is autoblocked, to track that user if
  20   they move to a new IP address. This is disabled by default.
  21

  32
  33 === Action API changes in 1.29 ===
  34 * Submitting sensitive authentication request parameters to action=clientlogin,
  35   action=createaccount, action=linkaccount, and action=changeauthenticationdata
  36   in the query string is now an error. They should be submitted in the POST
  37   body instead.
  38 * The capture option for action=resetpassword has been removed
  39 * action=clearhasmsg now requires a POST.
  40
  41 === Action API internal changes in 1.29 ===
  42
  43 === Languages updated in 1.29 ===
  44
  45 MediaWiki supports over 350 languages. Many localisations are updated
  46 regularly. Below only new and removed languages are listed, as well as
  47 changes to languages because of Phabricator reports.
  48
  49 ==== No fallback for Ukrainian ====
  50 * (T39314) The fallback from Ukrainian to Russian was removed. The Ukrainian
  51   language will now use the default fallback language: English. When a translation
  52   to Ukrainian is not available, an English string will be shown.
  53
  54 === Other changes in 1.29 ===
  55 * Database::getSearchEngine() (deprecated in 1.28) was removed. Use
  56   SearchEngineFactory::getSearchEngineClass() instead.
  57 * $wgSessionsInMemcached (deprecated in 1.20) was removed. No replacement is
  58   required as all sessions are stored in Object Cache now.
  59 * MWHttpRequest::execute() should be considered to return a StatusValue; the
  60   Status return type is deprecated.
  61
  62 == Compatibility ==
  63
  64 MediaWiki 1.29 requires PHP 5.5.9 or later. There is experimental support for
  65 HHVM 3.6.5 or later.
  66
  67 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  68 support for them is somewhat less mature. There is experimental support for
  69 Oracle and Microsoft SQL Server.
  70
  71 The supported versions are:
  72
  73 * MySQL 5.0.3 or later
  74 * PostgreSQL 8.3 or later
  75 * SQLite 3.3.7 or later
  76 * Oracle 9.0.1 or later
  77 * Microsoft SQL Server 2005 (9.00.1399)
  78
  79 == Upgrading ==
  80
  81 1.29 has several database changes since 1.28, and will not work without schema
  82 updates. Note that due to changes to some very large tables like the revision
  83 table, the schema update may take quite long (minutes on a medium sized site,
  84 many hours on a large site).
  85
  86 If upgrading from before 1.11, and you are using a wiki as a commons
  87 repository, make sure that it is updated as well. Otherwise, errors may arise
  88 due to database schema changes.
  89
  90 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
  91 new database fields are filled with data.
  92
  93 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
  94 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
  95 with MediaWiki 1.21.
  96
  97 Don't forget to always back up your database before upgrading!
  98
  99 See the file UPGRADE for more detailed upgrade instructions.
