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 * $wgCascadingRestrictionLevels was added.
  19
  20 === New features in 1.22 ===
  21 * (bug 44525) mediawiki.jqueryMsg can now parse (whitelisted) HTML elements and attributes.
  22 * (bug 33454) Language::sprintfDate now has a timezone parameter, and supports
  23   the "eIOPTZ" formatting characters.
  24 * EditWarning: A warning is shown when an editor leaves the edit form without
  25   saving (enabled by default, users can opt-out via the 'useeditwarning'
  26   preference). This feature was moved from the Vector extension, and is now part
  27   of core for all skins. Take care when upgrading that you don't use an older
  28   version of the Vector extension as this feature may conflict.
  29 * New 'mediawiki.ui' CSS module providing mw-ui-* styles for buttons and a
  30   compact vertical form layout.
  31 * New versions of login (Special:UserLogin) and create account
  32   (Special:UserLogin/signup) forms. They are opt-in for now, controlled by
  33   the $wgUseVFormUserLogin and $wgUseVFormCreateAccount settings or a 'useNew'
  34   URL parameter trigger.
  35 * (bug 23343) Implemented ability to apply IP blocks to the contents of X-Forwarded-For headers
  36   by adding a new configuration variable $wgApplyIpBlocksToXff (disabled by default).
  37 * The new hook 'APIGetPossibleErrors' to modify the list of possible errors was
  38   added.
  39 * (bug 25592) LogEventsList::showLogExtract() will now ignore various
  40   Pager-related WebRequest parameters by default, as this is overwhelmingly
  41   likely to be what was intended by users of the method. If any caller wishes
  42   to use these parameters, the new param 'useRequestParams' may be set to true.
  43 * mw.util.addPortletLink: Tooltip is no longer required to be plain (without
  44   an accesskey in it already). As such it now rountrips. Creating a link with a
  45   message as tooltip, grabbing the title attribute and using it to create
  46   another portlet will work as expected.
  47 * (bug 6747) {{ROOTPAGENAME}} introduced, contains the name of the topmost
  48   page without namespace.
  49 * BREAKING CHANGE: (bug 41729) Display editsection links next to headings. Also
  50   change their class name from .editsection to .mw-editsection and place them at
  51   the end of the heading element instead of the beginning. Client-side code and
  52   screen-scrapers will have to be adjusted to handle both cases (old HTML will
  53   still be visible on cached page renders until they are purged); extensions
  54   using the DoEditSectionLink or EditSectionLink hooks might need adjustments as
  55   well.
  56 * (bug 45535) introduced the new 'LanguageLinks' hook for manipulating the
  57   language links associated with a page before display.
  58 * Chosen (http://harvesthq.github.io/chosen/) was added as module 'jquery.chosen'
  59 * HTMLForm will turn multiselect checkboxes into a Chosen interface when setting cssclass 'mw-chosen'
  60 * rebuildLocalisationCache learned --lang option. Let you rebuild l10n caches
  61   of the specified languages instead of all of them.
  62 * New GetNewMessagesAlert hook allowing extensions to disable or modify the new
  63   messages alert
  64 * New wgUserNewMsgRevisionId JS global for logged in users. This will be null
  65   if the user has no new talk page messages. Otherwise it will be set to the
  66   revision ID of the oldest new talk page message. This will allow gadgets and
  67   extensions to create their own new message alerts on the client side.
  68 * mediawiki.log: Added log.warn wrapper (uses console.warn and console.trace).
  69 * mediawiki.log: Implemented log.deprecate. This method defines a property and
  70   uses ES5 getter/setter to emit a warning when they are used.
  71 * $wgCascadingRestrictionLevels was added, allowing one to specify restriction levels
  72   which can be cascading (previously 'sysop' was hard-coded as the only one).
  73
  74 === Bug fixes in 1.22 ===
  75 * Disable Special:PasswordReset when $wgEnableEmail. Previously one could still
  76   navigate to the page by entering the URL directly.
  77 * (bug 47138) Fixed a fatal error when a blocked user tries to automatically
  78   create an account on login due external authentication in some circumstances.
  79 * (bug 23393) HTML <hN> headings containing line breaks are now handled
  80   correctly.
  81 * (bug 45803) Whitespace within == Headline == syntax and within <hN> headings
  82   is now non-significant and not preserved in the HTML output.
  83 * (bug 47218) Special:BlockList now handles correctly user names with spaces
  84   when passed as subpage.
  85 * Pager's properly validate which fields are allowed to be sorted on.
  86 * mw.util.tooltipAccessKeyRegexp: The regex now matches "option-" as well.
  87   Support for Mac "option" was added in 1.16, but the regex was never updated.
  88 * (bug 46768) Usernames of blocking users now display correctly, even if numeric.
  89 * (bug 39590) {{PAGESIZE}} for the current page and self-transclusions now
  90   show the most up to date result always instead of being a revision behind.
  91 * A bias in wfRandomString() toward digits 1-7 has been corrected. Generated
  92   strings will now start with digits 0 and 8-f as often as they should.
  93 * (bug 45371) Removed Parser_LinkHooks and CoreLinkFunctions classes.
  94
  95 === API changes in 1.22 ===
  96 * (bug 46626) xmldoublequote parameter was removed. Because of a bug, the
  97   parameter has had no effect since MediaWiki 1.16, and so its removal is
  98   unlikely to impact existing clients.
  99 * (bug 25325) Added support for wlshow filtering (bots/anon/minor/patrolled)
 100   to action=feedwatchlist.
 101 * WDDX formatted output will actually be formatted (and normal output will no
 102   longer be), and will no longer choke on booleans.
 103 * action=opensearch no longer silently ignores the format parameter.
 104 * action=opensearch now supports format=jsonfm.
 105 * list=usercontribs&ucprop=ids will now include the parent revision id.
 106 * BREAKING CHANGE: action=parse no longer returns all langlinks for the page
 107   with prop=langlinks by default. The new effectivelanglinks parameter will
 108   request that the LanguageLinks hook be called to determine the effective
 109   language links.
 110 * BREAKING CHANGE: list=allpages, list=langbacklinks, and prop=langlinks do not
 111   apply the new LanguageLinks hook, and thus only consider language links
 112   stored in the database.
 113 * (bug 47219) Allow specifying change type of Wikipedia feed items
 114 * prop=imageinfo now allows setting iiurlheight without setting iiurlwidth
 115 * prop=info now adds the content model of the title.
 116 * New upload log entries will now contain information on the relavent
 117   image (sha1 and timestamp).
 118
 119 === Languages updated in 1.22===
 120
 121 MediaWiki supports over 350 languages. Many localisations are updated
 122 regularly. Below only new and removed languages are listed, as well as
 123 changes to languages because of Bugzilla reports.
 124
 125 * (bug 46751) Made Buryat (Russia) (буряад) (bxr) fallback to Russian.
 126
 127 === Other changes in 1.22 ===
 128 * redirect.php was removed. It was unused.
 129 * ClickTracking integration was dropped from the mediaWiki.user.bucket
 130   JavaScript function. The 'tracked' option is now ignored.
 131 * BREAKING CHANGE: Legacy skins Simple, MySkin, Chick, Standard and Nostalgia
 132   were all removed. (Nostalgia was moved to an extension.) The SkinLegacy and
 133   LegacyTemplate classes that supported them were removed as well and are now a
 134   part of the Nostalgia extension.
 135 * Event namespace used by jquery.makeCollapsible has been changed from
 136   'mw-collapse' to 'mw-collapsible' for consistency with the module name.
 137 * BREAKING CHANGE: The "ExternalAuth" authentication subsystem was removed, along
 138   with its associated globals of $wgExternalAuthType, $wgExternalAuthConf,
 139   $wgAutocreatePolicy and $wgAllowPrefChange. Affected users are encouraged to
 140   use AuthPlugin for external authentication/authorization needs.
 141 * The Quickbar feature of the legacy skin model and the last remnants of it
 142   throughout the code base have been removed.
 143 * Externaledit/externaldiff preference was removed. Very few users used this
 144   feature, and improper configuration can actually prevent a user from editing
 145 * Calling Linker methods using a skin will now output deprecation warnings.
 146 * (bug 46680) "Return to" links are no longer tagged with rel="next".
 147 * BREAKING CHANGE: mw.util.tooltipAccessKeyRegexp: The match group for the
 148   accesskey character is now $6 instead of $5.
 149 * HipHop compiler (hphpc) support was removed. HipHop VM support (hhvm) was
 150   added.
 151 * A new Special:Redirect page was added, providing lookup by revision ID,
 152   user ID, or file name.  The old Special:Filepath page was reimplemented
 153   to redirect through Special:Redirect.
 154 * Monobook: Removed the old conditional stylesheets for Opera 6, 7 and 9.
 155
 156 == Compatibility ==
 157
 158 MediaWiki 1.22 requires PHP 5.3.2 or later.
 159
 160 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 161 support for them is somewhat less mature. There is experimental support for
 162 Oracle.
 163
 164 The supported versions are:
 165
 166 * MySQL 5.0.2 or later
 167 * PostgreSQL 8.3 or later
 168 * SQLite 3.3.7 or later
 169 * Oracle 9.0.1 or later
 170
 171 == Upgrading ==
 172
 173 1.22 has several database changes since 1.21, and will not work without schema
 174 updates. Note that due to changes to some very large tables like the revision
 175 table, the schema update may take quite long (minutes on a medium sized site,
 176 many hours on a large site).
 177
 178 If upgrading from before 1.11, and you are using a wiki as a commons
 179 repository, make sure that it is updated as well. Otherwise, errors may arise
 180 due to database schema changes.
 181
 182 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 183 new database fields are filled with data.
 184
 185 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 186 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 187 with MediaWiki 1.21.
 188
 189 Don't forget to always back up your database before upgrading!
 190
 191 See the file UPGRADE for more detailed upgrade instructions.
