RELEASE-NOTES-1.22

   1 Security reminder: MediaWiki does not require PHP's register_globals. If you
   2 have it on, turn it '''off''' if you can.

   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 * The new hook 'APIGetPossibleErrors' to modify the list of possible errors was
  33   added.
  34
  35 === Bug fixes in 1.22 ===
  36 * Disable Special:PasswordReset when $wgEnableEmail. Previously one could still
  37   navigate to the page by entering the URL directly.
  38 * (bug 47138) Fixed a fatal error when a blocked user tries to automatically
  39   create an account on login due external authentication in some circumstances.
  40 * (bug 23393) HTML <hN> headings containing line breaks are now handled
  41   correctly.
  42 * (bug 45803) Whitespace within == Headline == syntax and within <hN> headings
  43   is now non-significant and not preserved in the HTML output.
  44 * (bug 47218) Special:BlockList now handles correctly user names with spaces
  45   when passed as subpage.
  46 * Pager's properly validate which fields are allowed to be sorted on.
  47
  48 === API changes in 1.22 ===
  49 * (bug 46626) xmldoublequote parameter was removed. Because of a bug, the
  50   parameter has had no effect since MediaWiki 1.16, and so its removal is
  51   unlikely to impact existing clients.
  52 * (bug 25325) Added support for wlshow filtering (bots/anon/minor/patrolled)
  53   to action=feedwatchlist.
  54 * WDDX formatted output will actually be formatted (and normal output will no
  55   longer be), and will no longer choke on booleans.
  56 * action=opensearch no longer silently ignores the format parameter.
  57 * action=opensearch now supports format=jsonfm.
  58
  59 === Languages updated in 1.22===
  60
  61 MediaWiki supports over 350 languages. Many localisations are updated
  62 regularly. Below only new and removed languages are listed, as well as
  63 changes to languages because of Bugzilla reports.
  64
  65 === Other changes in 1.22 ===
  66 * redirect.php was removed. It was unused.
  67 * ClickTracking integration was dropped from the mediaWiki.user.bucket
  68   JavaScript function. The 'tracked' option is now ignored.
  69 * BREAKING CHANGE: Legacy skins Simple, MySkin and Standard were all removed.
  70   Nostalgia was moved to an extension.
  71 * Event namespace used by jquery.makeCollapsible has been changed from
  72   'mw-collapse' to 'mw-collapsible' for consistency with the module name.
  73 * BREAKING CHANGE: The "ExternalAuth" authentication subsystem was removed, along
  74   with its associated globals of $wgExternalAuthType, $wgExternalAuthConf,
  75   $wgAutocreatePolicy and $wgAllowPrefChange. Affected users are encouraged to
  76   use AuthPlugin for external authentication/authorization needs.
  77 * The Quickbar feature of the legacy skin model and the last remnants of it
  78   throughout the code base have been removed.
  79 * Externaledit/externaldiff preference was removed. Very few users used this
  80   feature, and improper configuration can actually prevent a user from editing
  81 * Calling Linker methods using a skin will now output deprecation warnings.
  82 * (bug 46680) "Return to" links are no longer tagged with rel="next".
  83 * The Special:ActiveUsers special page was removed.
  84
  85 == Compatibility ==
  86
  87 MediaWiki 1.22 requires PHP 5.3.2 or later.
  88
  89 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  90 support for them is somewhat less mature. There is experimental support for
  91 Oracle.
  92
  93 The supported versions are:
  94
  95 * MySQL 5.0.2 or later
  96 * PostgreSQL 8.3 or later
  97 * SQLite 3.3.7 or later
  98 * Oracle 9.0.1 or later
  99
 100 == Upgrading ==
 101
 102 1.22 has several database changes since 1.21, and will not work without schema
 103 updates. Note that due to changes to some very large tables like the revision
 104 table, the schema update may take quite long (minutes on a medium sized site,
 105 many hours on a large site).
 106
 107 If upgrading from before 1.11, and you are using a wiki as a commons
 108 repository, make sure that it is updated as well. Otherwise, errors may arise
 109 due to database schema changes.
 110
 111 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 112 new database fields are filled with data.
 113
 114 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 115 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 116 with MediaWiki 1.21.
 117
 118 Don't forget to always back up your database before upgrading!
 119
 120 See the file UPGRADE for more detailed upgrade instructions.
