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