   4 == MediaWiki 1.22 ==
   5
   6 THIS IS NOT A RELEASE YET
   7
   8 MediaWiki 1.22 is an alpha-quality branch and is not recommended for use in
   9 production.
  10
  11 === Configuration changes in 1.22 ===
  12 * $wgRedirectScript was removed. It was unused.
  13 * Removed $wgLocalMessageCacheSerialized, it is now always true.
  14 * When $wgUseVFormUserLogin is true, the redesign of Special:UserLogin is
  15   activated.
  16 * $wgVectorUseIconWatch is now enabled by default.
  17
  18 === New features in 1.22 ===
  19 * (bug 44525) mediawiki.jqueryMsg can now parse (whitelisted) HTML elements and attributes.
  20 * (bug 33454) Language::sprintfDate now has a timezone parameter, and supports
  21   the "eIOPTZ" formatting characters.
  22 * EditWarning: A warning is shown when an editor leaves the edit form without
  23   saving (enabled by default, users can opt-out via the 'useeditwarning'
  24   preference). This feature was moved from the Vector extension, and is now part
  25   of core for all skins. Take care when upgrading that you don't use an older
  26   version of the Vector extension as this feature may conflict.
  27 * New version of Special:UserLogin form. It is opt-in for now, controlled by
  28   the $wgUseVFormUserLogin setting or a 'useNew' URL parameter trigger.
  29 * Added 'SpecialSearchResultsPrepend' and 'SpecialSearchResultsAppend' hooks.
  30 * (bug 23343) Implemented ability to apply IP blocks to the contents of X-Forwarded-For headers
  31   by adding a new configuration variable $wgApplyIpBlocksToXff (disabled by default).
  32
  33 === Bug fixes in 1.22 ===
  34 * Disable Special:PasswordReset when $wgEnableEmail. Previously one could still
  35   navigate to the page by entering the URL directly.
  36 * (bug 47138) Fixed a fatal error when a blocked user tries to automatically
  37   create an account on login due external authentication in some circumstances.
  38 * (bug 23393) HTML <hN> headings containing line breaks are now handled
  39   correctly.
  40 * (bug 45803) Whitespace within == Headline == syntax and within <hN> headings
  41   is now non-significant and not preserved in the HTML output.
  42 * (bug 47218) Special:BlockList now handles correctly user names with spaces
  43   when passed as subpage.
  44
  45 === API changes in 1.22 ===
  46 * (bug 46626) xmldoublequote parameter was removed. Because of a bug, the
  47   parameter has had no effect since MediaWiki 1.16, and so its removal is
  48   unlikely to impact existing clients.
  49 * (bug 25325) Added support for wlshow filtering (bots/anon/minor/patrolled)
  50   to action=feedwatchlist.
  51 * WDDX formatted output will actually be formatted (and normal output will no
  52   longer be), and will no longer choke on booleans.
  53 * action=opensearch no longer silently ignores the format parameter.
  54 * action=opensearch now supports format=jsonfm.
  55
  56 === Languages updated in 1.22===
  57
  58 MediaWiki supports over 350 languages. Many localisations are updated
  59 regularly. Below only new and removed languages are listed, as well as
  60 changes to languages because of Bugzilla reports.
  61
  62 === Other changes in 1.22 ===
  63 * redirect.php was removed. It was unused.
  64 * ClickTracking integration was dropped from the mediaWiki.user.bucket
  65   JavaScript function. The 'tracked' option is now ignored.
  66 * BREAKING CHANGE: Legacy skins Simple, MySkin and Standard were all removed.
  67   Nostalgia was moved to an extension.
  68 * Event namespace used by jquery.makeCollapsible has been changed from
  69   'mw-collapse' to 'mw-collapsible' for consistency with the module name.
  70 * BREAKING CHANGE: The "ExternalAuth" authentication subsystem was removed, along
  71   with its associated globals of $wgExternalAuthType, $wgExternalAuthConf,
  72   $wgAutocreatePolicy and $wgAllowPrefChange. Affected users are encouraged to
  73   use AuthPlugin for external authentication/authorization needs.
  74 * The Quickbar feature of the legacy skin model and the last remnants of it
  75   throughout the code base have been removed.
  76 * Externaledit/externaldiff preference was removed. Very few users used this
  77   feature, and improper configuration can actually prevent a user from editing
  78 * Calling Linker methods using a skin will now output deprecation warnings.
  79 * (bug 46680) "Return to" links are no longer tagged with rel="next".
  80 * The Special:ActiveUsers special page was removed.
  81
  82 == Compatibility ==
  83
  84 MediaWiki 1.22 requires PHP 5.3.2 or later.
  85
  86 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  87 support for them is somewhat less mature. There is experimental support for
  88 Oracle.
  89
  90 The supported versions are:
  91
  92 * MySQL 5.0.2 or later
  93 * PostgreSQL 8.3 or later
  94 * SQLite 3.3.7 or later
  95 * Oracle 9.0.1 or later
  96
  97 == Upgrading ==
  98
  99 1.22 has several database changes since 1.21, and will not work without schema
 100 updates. Note that due to changes to some very large tables like the revision
 101 table, the schema update may take quite long (minutes on a medium sized site,
 102 many hours on a large site).
 103
 104 If upgrading from before 1.11, and you are using a wiki as a commons
 105 repository, make sure that it is updated as well. Otherwise, errors may arise
 106 due to database schema changes.
 107
 108 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 109 new database fields are filled with data.
 110
 111 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 112 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 113 with MediaWiki 1.21.
 114
 115 Don't forget to always back up your database before upgrading!
 116
 117 See the file UPGRADE for more detailed upgrade instructions.
