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 * ftps, ssh, sftp, xmpp, sip, sips, tel, sms, bitcoin, magnet, urn, and geo
  20   have been whitelisted inside of $wgUrlProtocols.
  21
  22 === New features in 1.22 ===
  23 * (bug 44525) mediawiki.jqueryMsg can now parse (whitelisted) HTML elements and attributes.
  24 * (bug 33454) Language::sprintfDate now has a timezone parameter, and supports
  25   the "eIOPTZ" formatting characters.
  26 * EditWarning: A warning is shown when an editor leaves the edit form without
  27   saving (enabled by default, users can opt-out via the 'useeditwarning'
  28   preference). This feature was moved from the Vector extension, and is now part
  29   of core for all skins. Take care when upgrading that you don't use an older
  30   version of the Vector extension as this feature may conflict.
  31 * New 'mediawiki.ui' CSS module providing mw-ui-* styles for buttons and a
  32   compact vertical form layout.
  33 * New versions of login (Special:UserLogin) and create account
  34   (Special:UserLogin/signup) forms. They are opt-in for now, controlled by
  35   the $wgUseVFormUserLogin and $wgUseVFormCreateAccount settings or a 'useNew'
  36   URL parameter trigger.
  37 * (bug 23343) Implemented ability to apply IP blocks to the contents of X-Forwarded-For headers
  38   by adding a new configuration variable $wgApplyIpBlocksToXff (disabled by default).
  39 * The new hook 'APIGetPossibleErrors' to modify the list of possible errors was
  40   added.
  41 * (bug 25592) LogEventsList::showLogExtract() will now ignore various
  42   Pager-related WebRequest parameters by default, as this is overwhelmingly
  43   likely to be what was intended by users of the method. If any caller wishes
  44   to use these parameters, the new param 'useRequestParams' may be set to true.
  45 * mw.util.addPortletLink: Tooltip is no longer required to be plain (without
  46   an accesskey in it already). As such it now rountrips. Creating a link with a
  47   message as tooltip, grabbing the title attribute and using it to create
  48   another portlet will work as expected.
  49 * (bug 6747) {{ROOTPAGENAME}} introduced, contains the name of the topmost
  50   page without namespace.
  51 * BREAKING CHANGE: (bug 41729) Display editsection links next to headings. Also
  52   change their class name from .editsection to .mw-editsection and place them at
  53   the end of the heading element instead of the beginning. Client-side code and
  54   screen-scrapers will have to be adjusted to handle both cases (old HTML will
  55   still be visible on cached page renders until they are purged); extensions
  56   using the DoEditSectionLink or EditSectionLink hooks might need adjustments as
  57   well.
  58 * (bug 45535) introduced the new 'LanguageLinks' hook for manipulating the
  59   language links associated with a page before display.
  60 * Chosen (http://harvesthq.github.io/chosen/) was added as module 'jquery.chosen'
  61 * HTMLForm will turn multiselect checkboxes into a Chosen interface when setting cssclass 'mw-chosen'
  62 * rebuildLocalisationCache learned --lang option. Let you rebuild l10n caches
  63   of the specified languages instead of all of them.
  64 * New GetNewMessagesAlert hook allowing extensions to disable or modify the new
  65   messages alert
  66 * New wgUserNewMsgRevisionId JS global for logged in users. This will be null
  67   if the user has no new talk page messages. Otherwise it will be set to the
  68   revision ID of the oldest new talk page message. This will allow gadgets and
  69   extensions to create their own new message alerts on the client side.
  70 * mediawiki.log: Added log.warn wrapper (uses console.warn and console.trace).
  71 * mediawiki.log: Implemented log.deprecate. This method defines a property and
  72   uses ES5 getter/setter to emit a warning when they are used.
  73 * $wgCascadingRestrictionLevels was added, allowing one to specify restriction levels
  74   which can be cascading (previously 'sysop' was hard-coded as the only one).
  75
  76 === Bug fixes in 1.22 ===
  77 * Disable Special:PasswordReset when $wgEnableEmail. Previously one could still
  78   navigate to the page by entering the URL directly.
  79 * (bug 47138) Fixed a fatal error when a blocked user tries to automatically
  80   create an account on login due external authentication in some circumstances.
  81 * (bug 23393) HTML <hN> headings containing line breaks are now handled
  82   correctly.
  83 * (bug 45803) Whitespace within == Headline == syntax and within <hN> headings
  84   is now non-significant and not preserved in the HTML output.
  85 * (bug 47218) Special:BlockList now handles correctly user names with spaces
  86   when passed as subpage.
  87 * Pager's properly validate which fields are allowed to be sorted on.
  88 * mw.util.tooltipAccessKeyRegexp: The regex now matches "option-" as well.
  89   Support for Mac "option" was added in 1.16, but the regex was never updated.
  90 * (bug 46768) Usernames of blocking users now display correctly, even if numeric.
  91 * (bug 39590) {{PAGESIZE}} for the current page and self-transclusions now
  92   show the most up to date result always instead of being a revision behind.
  93 * A bias in wfRandomString() toward digits 1-7 has been corrected. Generated
  94   strings will now start with digits 0 and 8-f as often as they should.
  95 * (bug 45371) Removed Parser_LinkHooks and CoreLinkFunctions classes.
  96
  97 === API changes in 1.22 ===
  98 * (bug 46626) xmldoublequote parameter was removed. Because of a bug, the
  99   parameter has had no effect since MediaWiki 1.16, and so its removal is
 100   unlikely to impact existing clients.
 101 * (bug 25325) Added support for wlshow filtering (bots/anon/minor/patrolled)
 102   to action=feedwatchlist.
 103 * WDDX formatted output will actually be formatted (and normal output will no
 104   longer be), and will no longer choke on booleans.
 105 * action=opensearch no longer silently ignores the format parameter.
 106 * action=opensearch now supports format=jsonfm.
 107 * list=usercontribs&ucprop=ids will now include the parent revision id.
 108 * BREAKING CHANGE: action=parse no longer returns all langlinks for the page
 109   with prop=langlinks by default. The new effectivelanglinks parameter will
 110   request that the LanguageLinks hook be called to determine the effective
 111   language links.
 112 * BREAKING CHANGE: list=allpages, list=langbacklinks, and prop=langlinks do not
 113   apply the new LanguageLinks hook, and thus only consider language links
 114   stored in the database.
 115 * (bug 47219) Allow specifying change type of Wikipedia feed items
 116 * prop=imageinfo now allows setting iiurlheight without setting iiurlwidth
 117 * prop=info now adds the content model of the title.
 118 * New upload log entries will now contain information on the relavent
 119   image (sha1 and timestamp).
 120
 121 === Languages updated in 1.22===
 122
 123 MediaWiki supports over 350 languages. Many localisations are updated
 124 regularly. Below only new and removed languages are listed, as well as
 125 changes to languages because of Bugzilla reports.
 126
 127 * (bug 46751) Made Buryat (Russia) (буряад) (bxr) fallback to Russian.
 128
 129 === Other changes in 1.22 ===
 130 * redirect.php was removed. It was unused.
 131 * ClickTracking integration was dropped from the mediaWiki.user.bucket
 132   JavaScript function. The 'tracked' option is now ignored.
 133 * BREAKING CHANGE: Legacy skins Simple, MySkin, Chick, Standard and Nostalgia
 134   were all removed. (Nostalgia was moved to an extension.) The SkinLegacy and
 135   LegacyTemplate classes that supported them were removed as well and are now a
 136   part of the Nostalgia extension.
 137 * Event namespace used by jquery.makeCollapsible has been changed from
 138   'mw-collapse' to 'mw-collapsible' for consistency with the module name.
 139 * BREAKING CHANGE: The "ExternalAuth" authentication subsystem was removed, along
 140   with its associated globals of $wgExternalAuthType, $wgExternalAuthConf,
 141   $wgAutocreatePolicy and $wgAllowPrefChange. Affected users are encouraged to
 142   use AuthPlugin for external authentication/authorization needs.
 143 * The Quickbar feature of the legacy skin model and the last remnants of it
 144   throughout the code base have been removed.
 145 * Externaledit/externaldiff preference was removed. Very few users used this
 146   feature, and improper configuration can actually prevent a user from editing
 147 * Calling Linker methods using a skin will now output deprecation warnings.
 148 * (bug 46680) "Return to" links are no longer tagged with rel="next".
 149 * BREAKING CHANGE: mw.util.tooltipAccessKeyRegexp: The match group for the
 150   accesskey character is now $6 instead of $5.
 151 * HipHop compiler (hphpc) support was removed. HipHop VM support (hhvm) was
 152   added.
 153 * A new Special:Redirect page was added, providing lookup by revision ID,
 154   user ID, or file name.  The old Special:Filepath page was reimplemented
 155   to redirect through Special:Redirect.
 156 * Monobook: Removed the old conditional stylesheets for Opera 6, 7 and 9.
 157
 158 == Compatibility ==
 159
 160 MediaWiki 1.22 requires PHP 5.3.2 or later.
 161
 162 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 163 support for them is somewhat less mature. There is experimental support for
 164 Oracle.
 165
 166 The supported versions are:
 167
 168 * MySQL 5.0.2 or later
 169 * PostgreSQL 8.3 or later
 170 * SQLite 3.3.7 or later
 171 * Oracle 9.0.1 or later
 172
 173 == Upgrading ==
 174
 175 1.22 has several database changes since 1.21, and will not work without schema
 176 updates. Note that due to changes to some very large tables like the revision
 177 table, the schema update may take quite long (minutes on a medium sized site,
 178 many hours on a large site).
 179
 180 If upgrading from before 1.11, and you are using a wiki as a commons
 181 repository, make sure that it is updated as well. Otherwise, errors may arise
 182 due to database schema changes.
 183
 184 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 185 new database fields are filled with data.
 186
 187 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 188 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 189 with MediaWiki 1.21.
 190
 191 Don't forget to always back up your database before upgrading!
 192
 193 See the file UPGRADE for more detailed upgrade instructions.
 194
 195 For notes on 1.21.x and older releases, see HISTORY.
