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