   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 * $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 * $wgDocType and $wgDTD have been removed and are no longer used for the DOCTYPE.
  22 * $wgHtml5 is no longer used by core. Setting it to false will no longer disable HTML5.
  23   It is still set to true for extension compatibility but doing so in extensions is deprecated.
  24 * $wgXhtmlDefaultNamespace is no longer used by core. Setting it will no longer change the
  25   xmlns used by MediaWiki. Reliance on this variable by extensions is deprecated.
  26 * $wgHandheldStyle was removed.
  27 * $wgHandheldForIPhone was removed.
  28 * $wgJsMimeType is no longer used by core. Most usage has been removed since
  29   HTML output is now exclusively HTML5.
  30 * $wgDBOracleDRCP added. True enables persistent connection with DRCP on Oracle.
  31 * $wgLogAutopatrol added to allow disabling logging of autopatrol edits in the logging table.
  32   default for $wgLogAutopatrol is true.
  33
  34 === New features in 1.22 ===
  35 * (bug 44525) mediawiki.jqueryMsg can now parse (whitelisted) HTML elements and attributes.
  36 * (bug 33454) Language::sprintfDate now has a timezone parameter, and supports
  37   the "eIOPTZ" formatting characters.
  38 * EditWarning: A warning is shown when an editor leaves the edit form without
  39   saving (enabled by default, users can opt-out via the 'useeditwarning'
  40   preference). This feature was moved from the Vector extension, and is now part
  41   of core for all skins. Take care when upgrading that you don't use an older
  42   version of the Vector extension as this feature may conflict.
  43 * New 'mediawiki.ui' CSS module providing mw-ui-* styles for buttons and a
  44   compact vertical form layout.
  45 * New versions of login (Special:UserLogin) and create account
  46   (Special:UserLogin/signup) forms. They are opt-in for now, controlled by
  47   the $wgUseVFormUserLogin and $wgUseVFormCreateAccount settings or a 'useNew'
  48   URL parameter trigger.
  49 * (bug 23343) Implemented ability to apply IP blocks to the contents of X-Forwarded-For headers
  50   by adding a new configuration variable $wgApplyIpBlocksToXff (disabled by default).
  51 * The new hook 'APIGetPossibleErrors' to modify the list of possible errors was
  52   added.
  53 * (bug 25592) LogEventsList::showLogExtract() will now ignore various
  54   Pager-related WebRequest parameters by default, as this is overwhelmingly
  55   likely to be what was intended by users of the method. If any caller wishes
  56   to use these parameters, the new param 'useRequestParams' may be set to true.
  57 * mw.util.addPortletLink: Tooltip is no longer required to be plain (without
  58   an accesskey in it already). As such it now rountrips. Creating a link with a
  59   message as tooltip, grabbing the title attribute and using it to create
  60   another portlet will work as expected.
  61 * (bug 6747) {{ROOTPAGENAME}} introduced, contains the name of the topmost
  62   page without namespace.
  63 * BREAKING CHANGE: (bug 41729) Display editsection links next to headings. Also
  64   change their class name from .editsection to .mw-editsection and place them at
  65   the end of the heading element instead of the beginning. Client-side code and
  66   screen-scrapers will have to be adjusted to handle both cases (old HTML will
  67   still be visible on cached page renders until they are purged); extensions
  68   using the DoEditSectionLink or EditSectionLink hooks might need adjustments as
  69   well.
  70 * (bug 45535) introduced the new 'LanguageLinks' hook for manipulating the
  71   language links associated with a page before display.
  72 * Chosen (http://harvesthq.github.io/chosen/) was added as module 'jquery.chosen'
  73 * HTMLForm will turn multiselect checkboxes into a Chosen interface when setting cssclass 'mw-chosen'
  74 * rebuildLocalisationCache learned --lang option. Let you rebuild l10n caches
  75   of the specified languages instead of all of them.
  76 * New GetNewMessagesAlert hook allowing extensions to disable or modify the new
  77   messages alert
  78 * New wgUserNewMsgRevisionId JS global for logged in users. This will be null
  79   if the user has no new talk page messages. Otherwise it will be set to the
  80   revision ID of the oldest new talk page message. This will allow gadgets and
  81   extensions to create their own new message alerts on the client side.
  82 * mediawiki.log: Added log.warn wrapper (uses console.warn and console.trace).
  83 * mediawiki.log: Implemented log.deprecate. This method defines a property and
  84   uses ES5 getter/setter to emit a warning when they are used.
  85 * $wgCascadingRestrictionLevels was added, allowing one to specify restriction levels
  86   which can be cascading (previously 'sysop' was hard-coded as the only one).
  87 * XHTML5 support has been improved. If you set $wgMimeType = 'application/xhtml+xml'
  88   MediaWiki will try outputting markup acording to XHTML5 rules.
  89 * New hook 'TitleSquidURLs' for manipulating the list of URLs to be purged from
  90   HTTP caches when a page is changed.
  91 * Changed the patrolling system to always show the link for patrolling in case the
  92   current revision is patrollable. This also removed the usage of the rcid URI parameters.
  93 * Oracle DB backend now supports Database Resident Connection Pooling (DRCP).
  94   Can be enabled by setting $wgDBOracleDRCP=true.
  95   Requires Oracle DB 11gR1 or above, enabled DRCP inside the DB itself and a
  96   propper connect string.
  97   More about DRCP can be found at:
  98   http://www.oracle-base.com/articles/11g/database-resident-connection-pool-11gr1.php
  99 * Add a new parameter $patrolFooterShown to hook ArticleViewFooter so the hook
 100   handlers can take further action based on the status of the patrol footer
 101 * LinkCache singleton can now be altered or cleared, letting one to specify
 102   another instance that does not rely on a database backend.
 103 * MediaWiki's PHPUnit tests can now use PHPUnit installed using composer --dev.
 104
 105 === Bug fixes in 1.22 ===
 106 * Disable Special:PasswordReset when $wgEnableEmail is false. Previously one
 107   could still navigate to the page by entering the URL directly.
 108 * (bug 47138) Fixed a fatal error when a blocked user tries to automatically
 109   create an account on login due external authentication in some circumstances.
 110 * (bug 23393) HTML <hN> headings containing line breaks are now handled
 111   correctly.
 112 * (bug 45803) Whitespace within == Headline == syntax and within <hN> headings
 113   is now non-significant and not preserved in the HTML output.
 114 * (bug 47218) Special:BlockList now handles correctly user names with spaces
 115   when passed as subpage.
 116 * Pager's properly validate which fields are allowed to be sorted on.
 117 * mw.util.tooltipAccessKeyRegexp: The regex now matches "option-" as well.
 118   Support for Mac "option" was added in 1.16, but the regex was never updated.
 119 * (bug 46768) Usernames of blocking users now display correctly, even if numeric.
 120 * (bug 39590) {{PAGESIZE}} for the current page and self-transclusions now
 121   show the most up to date result always instead of being a revision behind.
 122 * A bias in wfRandomString() toward digits 1-7 has been corrected. Generated
 123   strings will now start with digits 0 and 8-f as often as they should.
 124 * (bug 45371) Removed Parser_LinkHooks and CoreLinkFunctions classes.
 125 * (bug 41545) Allow <kbd>, <samp>, and <var> to be nested like allowed in html.
 126 * PLURAL magic word no longer causes a PHP notice when no matching form exists.
 127 * (bug 36641) Patrol page links no longer show on non-existent revisions.
 128 * (bug 35810) Pages not linked from Special:RecentChanges or Special:NewPages
 129   are patrollable now.
 130 * (bug 30213) JavaScript for search suggestions is now disabled when the API
 131   is disabled, and AJAX patrolling and watching are now disabled when use of
 132   the write API is not allowed.
 133 * (bug 48294) API: Fix chunk upload async mode.
 134 * (bug 46749) Broken files tracking category removed from pages if an image
 135   with that name is uploaded.
 136
 137 === API changes in 1.22 ===
 138 * (bug 46626) xmldoublequote parameter was removed. Because of a bug, the
 139   parameter has had no effect since MediaWiki 1.16, and so its removal is
 140   unlikely to impact existing clients.
 141 * (bug 47216) action=query&meta=siteinfo&siprop=skins will now indicate which
 142   skin is the default and which are unusable (e.g. listed in $wgSkipSkins).
 143 * (bug 25325) Added support for wlshow filtering (bots/anon/minor/patrolled)
 144   to action=feedwatchlist.
 145 * WDDX formatted output will actually be formatted (and normal output will no
 146   longer be), and will no longer choke on booleans.
 147 * action=opensearch no longer silently ignores the format parameter.
 148 * action=opensearch now supports format=jsonfm.
 149 * list=usercontribs&ucprop=ids will now include the parent revision id.
 150 * BREAKING CHANGE: action=parse no longer returns all langlinks for the page
 151   with prop=langlinks by default. The new effectivelanglinks parameter will
 152   request that the LanguageLinks hook be called to determine the effective
 153   language links.
 154 * BREAKING CHANGE: list=allpages, list=langbacklinks, and prop=langlinks do not
 155   apply the new LanguageLinks hook, and thus only consider language links
 156   stored in the database.
 157 * (bug 47219) Allow specifying change type of Wikipedia feed items
 158 * prop=imageinfo now allows setting iiurlheight without setting iiurlwidth
 159 * prop=info now adds the content model and page language of the title.
 160 * New upload log entries will now contain information on the relavent
 161   image (sha1 and timestamp).
 162 * (bug 49239) action=parse now can parse in preview mode.
 163
 164 === Languages updated in 1.22===
 165
 166 MediaWiki supports over 350 languages. Many localisations are updated
 167 regularly. Below only new and removed languages are listed, as well as
 168 changes to languages because of Bugzilla reports.
 169
 170 * Batak Toba (bbc-latn) added.
 171 * (bug 46751) Made Buryat (Russia) (буряад) (bxr) fallback to Russian.
 172
 173 === Other changes in 1.22 ===
 174 * redirect.php was removed. It was unused.
 175 * ClickTracking integration was dropped from the mediaWiki.user.bucket
 176   JavaScript function. The 'tracked' option is now ignored.
 177 * BREAKING CHANGE: Legacy skins Simple, MySkin, Chick, Standard and Nostalgia
 178   were all removed. (Nostalgia was moved to an extension.) The SkinLegacy and
 179   LegacyTemplate classes that supported them were removed as well and are now a
 180   part of the Nostalgia extension.
 181 * Event namespace used by jquery.makeCollapsible has been changed from
 182   'mw-collapse' to 'mw-collapsible' for consistency with the module name.
 183 * BREAKING CHANGE: The "ExternalAuth" authentication subsystem was removed, along
 184   with its associated globals of $wgExternalAuthType, $wgExternalAuthConf,
 185   $wgAutocreatePolicy and $wgAllowPrefChange. Affected users are encouraged to
 186   use AuthPlugin for external authentication/authorization needs.
 187 * The Quickbar feature of the legacy skin model and the last remnants of it
 188   throughout the code base have been removed.
 189 * Externaledit/externaldiff preference was removed. Very few users used this
 190   feature, and improper configuration can actually prevent a user from editing
 191 * Calling Linker methods using a skin will now output deprecation warnings.
 192 * (bug 46680) "Return to" links are no longer tagged with rel="next".
 193 * BREAKING CHANGE: mw.util.tooltipAccessKeyRegexp: The match group for the
 194   accesskey character is now $6 instead of $5.
 195 * HipHop compiler (hphpc) support was removed. HipHop VM support (hhvm) was
 196   added.
 197 * A new Special:Redirect page was added, providing lookup by revision ID,
 198   user ID, or file name.  The old Special:Filepath page was reimplemented
 199   to redirect through Special:Redirect.
 200 * Monobook: Removed the old conditional stylesheets for Opera 6, 7 and 9.
 201 * Support for XHTML 1.0 has been removed. MediaWiki now only outputs (X)HTML5.
 202 * wikibits: User-agent related globals have been deprecated. The following
 203   properties now default to false and emit mw.log.warn: is_gecko, is_chrome_mac,
 204   is_chrome, webkit_version, is_safari_win, is_safari, webkit_match, is_ff2,
 205   ff2_bugs, is_ff2_win, is_ff2_x11, opera95_bugs, opera7_bugs, opera6_bugs,
 206   is_opera_95, is_opera_preseven, is_opera, and ie6_bugs.
 207 * (bug 48276) MediaWiki will now flash a confirmation message upon successfully
 208   editing a page.
 209 * (bug 40785) mediawiki.legacy.ajax has been marked as deprecated. The following
 210   properties now emit mw.log.warn when accessed: sajax_debug, sajax_init_object,
 211   sajax_do_call and wfSupportsAjax.
 212
 213 == Compatibility ==
 214
 215 MediaWiki 1.22 requires PHP 5.3.2 or later.
 216
 217 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 218 support for them is somewhat less mature. There is experimental support for
 219 Oracle.
 220
 221 The supported versions are:
 222
 223 * MySQL 5.0.2 or later
 224 * PostgreSQL 8.3 or later
 225 * SQLite 3.3.7 or later
 226 * Oracle 9.0.1 or later
 227
 228 == Upgrading ==
 229
 230 1.22 has several database changes since 1.21, and will not work without schema
 231 updates. Note that due to changes to some very large tables like the revision
 232 table, the schema update may take quite long (minutes on a medium sized site,
 233 many hours on a large site).
 234
 235 If upgrading from before 1.11, and you are using a wiki as a commons
 236 repository, make sure that it is updated as well. Otherwise, errors may arise
 237 due to database schema changes.
 238
 239 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 240 new database fields are filled with data.
 241
 242 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 243 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 244 with MediaWiki 1.21.
 245
 246 Don't forget to always back up your database before upgrading!
 247
 248 See the file UPGRADE for more detailed upgrade instructions.
 249
 250 For notes on 1.21.x and older releases, see HISTORY.
 251
 252 == Online documentation ==

 258         https://www.mediawiki.org/wiki/Documentation
 259
 260 == Mailing list ==
 261
 262 A mailing list is available for MediaWiki user support and discussion:
 263
 264         https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 265
 266 A low-traffic announcements-only list is also available:

 271 going to run a public MediaWiki, so you can be notified of security fixes.
 272
 273 == IRC help ==
 274
 275 There's usually someone online in #mediawiki on irc.freenode.net.
