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.

   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; when $wgUseVFormCreateAccount is true, the redesign of
  16   Special:UserLogin/signup is activated.
  17 * $wgVectorUseIconWatch is now enabled by default.
  18
  19 === New features in 1.22 ===
  20 * (bug 44525) mediawiki.jqueryMsg can now parse (whitelisted) HTML elements and attributes.
  21 * (bug 33454) Language::sprintfDate now has a timezone parameter, and supports
  22   the "eIOPTZ" formatting characters.
  23 * EditWarning: A warning is shown when an editor leaves the edit form without
  24   saving (enabled by default, users can opt-out via the 'useeditwarning'
  25   preference). This feature was moved from the Vector extension, and is now part
  26   of core for all skins. Take care when upgrading that you don't use an older
  27   version of the Vector extension as this feature may conflict.
  28 * New 'mediawiki.ui' CSS module providing mw-ui-* styles for buttons and a
  29   compact vertical form layout.
  30 * New versions of login (Special:UserLogin) and create account
  31   (Special:UserLogin/signup) forms. They are opt-in for now, controlled by
  32   the $wgUseVFormUserLogin and $wgUseVFormCreateAccount settings or a 'useNew'
  33   URL parameter trigger.
  34 * (bug 23343) Implemented ability to apply IP blocks to the contents of X-Forwarded-For headers
  35   by adding a new configuration variable $wgApplyIpBlocksToXff (disabled by default).
  36 * The new hook 'APIGetPossibleErrors' to modify the list of possible errors was
  37   added.
  38 * (bug 25592) LogEventsList::showLogExtract() will now ignore various
  39   Pager-related WebRequest parameters by default, as this is overwhelmingly
  40   likely to be what was intended by users of the method. If any caller wishes
  41   to use these parameters, the new param 'useRequestParams' may be set to true.
  42 * mw.util.addPortletLink: Tooltip is no longer required to be plain (without
  43   an accesskey in it already). As such it now rountrips. Creating a link with a
  44   message as tooltip, grabbing the title attribute and using it to create
  45   another portlet will work as expected.
  46 * (bug 6747) {{ROOTPAGENAME}} introduced, contains the name of the topmost
  47   page without namespace.
  48
  49 === Bug fixes in 1.22 ===
  50 * Disable Special:PasswordReset when $wgEnableEmail. Previously one could still
  51   navigate to the page by entering the URL directly.
  52 * (bug 47138) Fixed a fatal error when a blocked user tries to automatically
  53   create an account on login due external authentication in some circumstances.
  54 * (bug 23393) HTML <hN> headings containing line breaks are now handled
  55   correctly.
  56 * (bug 45803) Whitespace within == Headline == syntax and within <hN> headings
  57   is now non-significant and not preserved in the HTML output.
  58 * (bug 47218) Special:BlockList now handles correctly user names with spaces
  59   when passed as subpage.
  60 * Pager's properly validate which fields are allowed to be sorted on.
  61 * mw.util.tooltipAccessKeyRegexp: The regex now matches "option-" as well.
  62   Support for Mac "option" was added in 1.16, but the regex was never updated.
  63 * (bug 46768) Usernames of blocking users now display correctly, even if numeric.
  64
  65 === API changes in 1.22 ===
  66 * (bug 46626) xmldoublequote parameter was removed. Because of a bug, the
  67   parameter has had no effect since MediaWiki 1.16, and so its removal is
  68   unlikely to impact existing clients.
  69 * (bug 25325) Added support for wlshow filtering (bots/anon/minor/patrolled)
  70   to action=feedwatchlist.
  71 * WDDX formatted output will actually be formatted (and normal output will no
  72   longer be), and will no longer choke on booleans.
  73 * action=opensearch no longer silently ignores the format parameter.
  74 * action=opensearch now supports format=jsonfm.
  75
  76 === Languages updated in 1.22===
  77
  78 MediaWiki supports over 350 languages. Many localisations are updated
  79 regularly. Below only new and removed languages are listed, as well as
  80 changes to languages because of Bugzilla reports.
  81
  82 === Other changes in 1.22 ===
  83 * redirect.php was removed. It was unused.
  84 * ClickTracking integration was dropped from the mediaWiki.user.bucket
  85   JavaScript function. The 'tracked' option is now ignored.
  86 * BREAKING CHANGE: Legacy skins Simple, MySkin and Standard were all removed.
  87   Nostalgia was moved to an extension.
  88 * Event namespace used by jquery.makeCollapsible has been changed from
  89   'mw-collapse' to 'mw-collapsible' for consistency with the module name.
  90 * BREAKING CHANGE: The "ExternalAuth" authentication subsystem was removed, along
  91   with its associated globals of $wgExternalAuthType, $wgExternalAuthConf,
  92   $wgAutocreatePolicy and $wgAllowPrefChange. Affected users are encouraged to
  93   use AuthPlugin for external authentication/authorization needs.
  94 * The Quickbar feature of the legacy skin model and the last remnants of it
  95   throughout the code base have been removed.
  96 * Externaledit/externaldiff preference was removed. Very few users used this
  97   feature, and improper configuration can actually prevent a user from editing
  98 * Calling Linker methods using a skin will now output deprecation warnings.
  99 * (bug 46680) "Return to" links are no longer tagged with rel="next".
 100 * The Special:ActiveUsers special page was removed.
 101 * BREAKING CHANGE: mw.util.tooltipAccessKeyRegexp: The match group for the
 102   accesskey character is now $6 instead of $5.
 103
 104 == Compatibility ==
 105
 106 MediaWiki 1.22 requires PHP 5.3.2 or later.
 107
 108 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 109 support for them is somewhat less mature. There is experimental support for
 110 Oracle.
 111
 112 The supported versions are:
 113
 114 * MySQL 5.0.2 or later
 115 * PostgreSQL 8.3 or later
 116 * SQLite 3.3.7 or later
 117 * Oracle 9.0.1 or later
 118
 119 == Upgrading ==
 120
 121 1.22 has several database changes since 1.21, and will not work without schema
 122 updates. Note that due to changes to some very large tables like the revision
 123 table, the schema update may take quite long (minutes on a medium sized site,
 124 many hours on a large site).
 125
 126 If upgrading from before 1.11, and you are using a wiki as a commons
 127 repository, make sure that it is updated as well. Otherwise, errors may arise
 128 due to database schema changes.
 129
 130 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 131 new database fields are filled with data.
 132
 133 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 134 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 135 with MediaWiki 1.21.
 136
 137 Don't forget to always back up your database before upgrading!
 138
 139 See the file UPGRADE for more detailed upgrade instructions.
