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; 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 * BREAKING CHANGE: (bug 41729) Display editsection links next to headings. Also
  49   change their class name from .editsection to .mw-editsection and place them at
  50   the end of the heading element instead of the beginning. Client-side code and
  51   screen-scrapers will have to be adjusted to handle both cases (old HTML will
  52   still be visible on cached page renders until they are purged); extensions
  53   using the DoEditSectionLink or EditSectionLink hooks might need adjustments as
  54   well.
  55 * (bug 45535) introduced the new 'LanguageLinks' hook for manipulating the
  56   language links associated with a page before display.
  57 * Chosen (http://harvesthq.github.io/chosen/) was added as module 'jquery.chosen'
  58 * HTMLForm will turn multiselect checkboxes into a Chosen interface when setting cssclass 'mw-chosen'
  59 * rebuildLocalisationCache learned --lang option. Let you rebuild l10n caches
  60   of the specified languages instead of all of them.
  61 * New GetNewMessagesAlert hook allowing extensions to disable or modify the new
  62   messages alert
  63 * New wgUserNewMsgRevisionId JS global for logged in users. This will be null
  64   if the user has no new talk page messages. Otherwise it will be set to the
  65   revision ID of the oldest new talk page message. This will allow gadgets and
  66   extensions to create their own new message alerts on the client side.
  67 * mediawiki.log: Added log.warn wrapper (uses console.warn and console.trace).
  68 * mediawiki.log: Implemented log.deprecate. This method defines a property and
  69   uses ES5 getter/setter to emit a warning when they are used.
  70
  71 === Bug fixes in 1.22 ===
  72 * Disable Special:PasswordReset when $wgEnableEmail. Previously one could still
  73   navigate to the page by entering the URL directly.
  74 * (bug 47138) Fixed a fatal error when a blocked user tries to automatically
  75   create an account on login due external authentication in some circumstances.
  76 * (bug 23393) HTML <hN> headings containing line breaks are now handled
  77   correctly.
  78 * (bug 45803) Whitespace within == Headline == syntax and within <hN> headings
  79   is now non-significant and not preserved in the HTML output.
  80 * (bug 47218) Special:BlockList now handles correctly user names with spaces
  81   when passed as subpage.
  82 * Pager's properly validate which fields are allowed to be sorted on.
  83 * mw.util.tooltipAccessKeyRegexp: The regex now matches "option-" as well.
  84   Support for Mac "option" was added in 1.16, but the regex was never updated.
  85 * (bug 46768) Usernames of blocking users now display correctly, even if numeric.
  86 * (bug 39590) {{PAGESIZE}} for the current page and self-transclusions now
  87   show the most up to date result always instead of being a revision behind.
  88 * A bias in wfRandomString() toward digits 1-7 has been corrected. Generated
  89   strings will now start with digits 0 and 8-f as often as they should.
  90
  91 === API changes in 1.22 ===
  92 * (bug 46626) xmldoublequote parameter was removed. Because of a bug, the
  93   parameter has had no effect since MediaWiki 1.16, and so its removal is
  94   unlikely to impact existing clients.
  95 * (bug 25325) Added support for wlshow filtering (bots/anon/minor/patrolled)
  96   to action=feedwatchlist.
  97 * WDDX formatted output will actually be formatted (and normal output will no
  98   longer be), and will no longer choke on booleans.
  99 * action=opensearch no longer silently ignores the format parameter.
 100 * action=opensearch now supports format=jsonfm.
 101 * list=usercontribs&ucprop=ids will now include the parent revision id.
 102 * BREAKING CHANGE: action=parse no longer returns all langlinks for the page
 103   with prop=langlinks by default. The new effectivelanglinks parameter will
 104   request that the LanguageLinks hook be called to determine the effective
 105   language links.
 106 * BREAKING CHANGE: list=allpages, list=langbacklinks, and prop=langlinks do not
 107   apply the new LanguageLinks hook, and thus only consider language links
 108   stored in the database.
 109 * (bug 47219) Allow specifying change type of Wikipedia feed items
 110 * prop=imageinfo now allows setting iiurlheight without setting iiurlwidth
 111
 112 === Languages updated in 1.22===
 113
 114 MediaWiki supports over 350 languages. Many localisations are updated
 115 regularly. Below only new and removed languages are listed, as well as
 116 changes to languages because of Bugzilla reports.
 117
 118 === Other changes in 1.22 ===
 119 * redirect.php was removed. It was unused.
 120 * ClickTracking integration was dropped from the mediaWiki.user.bucket
 121   JavaScript function. The 'tracked' option is now ignored.
 122 * BREAKING CHANGE: Legacy skins Simple, MySkin, Chick, Standard and Nostalgia
 123   were all removed. (Nostalgia was moved to an extension.) The SkinLegacy and
 124   LegacyTemplate classes that supported them were removed as well and are now a
 125   part of the Nostalgia extension.
 126 * Event namespace used by jquery.makeCollapsible has been changed from
 127   'mw-collapse' to 'mw-collapsible' for consistency with the module name.
 128 * BREAKING CHANGE: The "ExternalAuth" authentication subsystem was removed, along
 129   with its associated globals of $wgExternalAuthType, $wgExternalAuthConf,
 130   $wgAutocreatePolicy and $wgAllowPrefChange. Affected users are encouraged to
 131   use AuthPlugin for external authentication/authorization needs.
 132 * The Quickbar feature of the legacy skin model and the last remnants of it
 133   throughout the code base have been removed.
 134 * Externaledit/externaldiff preference was removed. Very few users used this
 135   feature, and improper configuration can actually prevent a user from editing
 136 * Calling Linker methods using a skin will now output deprecation warnings.
 137 * (bug 46680) "Return to" links are no longer tagged with rel="next".
 138 * BREAKING CHANGE: mw.util.tooltipAccessKeyRegexp: The match group for the
 139   accesskey character is now $6 instead of $5.
 140 * HipHop compiler (hphpc) support was removed. HipHop VM support (hhvm) was
 141   added.
 142 * A new Special:Redirect page was added, providing lookup by revision ID,
 143   user ID, or file name.  The old Special:Filepath page was reimplemented
 144   to redirect through Special:Redirect.
 145 * Monobook: Removed the old conditional stylesheets for Opera 6, 7 and 9.
 146
 147 == Compatibility ==
 148
 149 MediaWiki 1.22 requires PHP 5.3.2 or later.
 150
 151 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 152 support for them is somewhat less mature. There is experimental support for
 153 Oracle.
 154
 155 The supported versions are:
 156
 157 * MySQL 5.0.2 or later
 158 * PostgreSQL 8.3 or later
 159 * SQLite 3.3.7 or later
 160 * Oracle 9.0.1 or later
 161
 162 == Upgrading ==
 163
 164 1.22 has several database changes since 1.21, and will not work without schema
 165 updates. Note that due to changes to some very large tables like the revision
 166 table, the schema update may take quite long (minutes on a medium sized site,
 167 many hours on a large site).
 168
 169 If upgrading from before 1.11, and you are using a wiki as a commons
 170 repository, make sure that it is updated as well. Otherwise, errors may arise
 171 due to database schema changes.
 172
 173 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 174 new database fields are filled with data.
 175
 176 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 177 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 178 with MediaWiki 1.21.
 179
 180 Don't forget to always back up your database before upgrading!
 181
 182 See the file UPGRADE for more detailed upgrade instructions.
