RELEASE-NOTES-1.24

   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 1.24 ==
   5
   6 THIS IS NOT A RELEASE YET
   7
   8 MediaWiki 1.24 is an alpha-quality branch and is not recommended for use in
   9 production.
  10
  11 === Configuration changes in 1.24 ===
  12 * The server's canonical hostname is available as $wgServerName, which is
  13   exposed in both mw.config and ApiQuerySiteInfo.
  14 * Introduced $wgPagePropsHaveSortkey as a backwards-compatibility switch,
  15   for using the old schema of the page_props table, in case the respective
  16   schema update was not applied.
  17 * $wgSearchEverythingOnlyLoggedIn was removed as the 'searcheverything'
  18   user option was removed. Use $wgNamespacesToBeSearchedDefault instead or
  19   if you used to have $wgDefaultUserOptions['searcheverything'] = 1.
  20 * $wgMasterWaitTimeout has been deprecated.
  21 * $wgDBClusterTimeout has been removed.
  22 * $wgProxyKey has been removed. It is no longer used by MediaWiki core.
  23   Ensure $wgSecretKey is set in LocalSettings.php.
  24
  25 === New features in 1.24 ===
  26 * Added a new hook, "WhatLinksHereProps", to allow extensions to annotate
  27   WhatLinksHere entries.
  28 * Added a new hook, "ContentGetParserOutput", to customize parser output for
  29   a given content object.
  30 * Deprecated the hook "ShowRawCssJs", use "ContentGetParserOutput" instead.
  31 * HTMLForm's HTMLTextField now supports the 'url' type.
  32 * HTMLForm fields may now be dynamically hidden based on the values of other
  33   fields in the form.
  34 * HTMLForm now supports multiple copies of an input field or set of input
  35   fields, e.g. the form may request "one or more usernames" without having to
  36   have the user enter delimited list of names into a text field.
  37 * Added a new hook, "SidebarBeforeOutput", to allow to edit the structure of
  38   the sidebar just before its display.
  39 * (bug 49156) Added the mediawiki.cookie ResourceLoader module, which wraps
  40   jquery.cookie so that getting/setting a cookie is syntactically and
  41   functionally similar to using the WebRequest::getCookie() and
  42   WebResponse::setcookie() methods.
  43 * (bug 44740) jQuery upgraded from 1.8.3 to 1.11.1. A new configuration option,
  44   $wgIncludejQueryMigrate, also loads the jQuery Migrate hack to let extensions
  45   and gadgets use the long-deprecated functions that were removed in jQuery 1.9.
  46   This option is turned off by default, and will be removed in MediaWiki 1.25.
  47 * (bug 47076) jQuery UI upgraded from 1.8.24 to 1.9.2.
  48 * Changes to content typography (fonts, etc.). See
  49   https://www.mediawiki.org/wiki/Typography_refresh for further information.
  50 * WikitextContent will now render redirects with the expected "redirect"
  51   header, rather than as an ordered list. Code calling Article::viewRedirect
  52   can probably be changed to no longer special-case redirects.
  53 * Header font set to a serif font stack. See
  54   https://www.mediawiki.org/wiki/Typography_refresh for further information.
  55 * (bug 65567) Added a new hook, "BeforeHttpsRedirect", to allow cancellation of
  56   the HTTP to HTTPS redirect due to forceHTTPS cookie, userRequires, etc. This
  57   is only for page views, since this hook doesn't affect UserLogin, OAuth,
  58   CentralAuth, etc. ATTENTION: This hook is likely to be removed soon due to
  59   overall design of the system.
  60 * (bug 17367) It is now possible to add pages to your watchlist from
  61   Special:UnwatchedPages without reloading the special page.
  62 * New methods setVolatile and isVolatile are added to PPFrame, so that
  63   extensions such as Cite.php can mark that their output is volatile and
  64   shouldn't be cached.
  65 * (bug 52817) Advanced search options are now saved on the search page itself,
  66   rather than in a dedicated pane in the preferences panel.
  67 * (bug 44591) The dropdown actions menu (little triangle next to page tabs) in
  68   the Vector skin has gained a label that should make it more discoverable.
  69 * MWCryptHKDF added for fast, cryptographically secure random number generation
  70   that won't deplete openssl's entropy pool.
  71 * ResourceLoader: File modules can now provide a skip function that uses an
  72   inline feature test to bypass loading of the module.
  73 * (bug 20210) Special pages may now provide autocompletion of their subpage
  74   names in search suggestions. Right now the only useful implementation is in
  75   Special:Log, but more are to come.
  76 * Special:MostLinkedTemplates is no longer limited to transclusions from the
  77   Template namespace.
  78
  79 === Bug fixes in 1.24 ===
  80 * (bug 49116) Footer copyright notice is now always displayed in user language
  81   rather than content language (same as copyright notice for editing interface).
  82 * (bug 62258) A bug was fixed in File::getUnscaledThumb when a height
  83   restriction was present in the parameters. Images with both the "frame"
  84   option and a size specification set will now always ignore the provided
  85   size and display an unscaled image, as the documentation has always
  86   claimed it would.
  87 * (bug 39035) Improved Vector skin performance by removing collapsibleNav,
  88   which used to collapse some sidebar elements by default.
  89   This removes -list id suffixes like p-lang-list: instead of using things like
  90   #p-lang-list, you can do #p-lang .body ul.
  91 * (bug 890) Links in Special:RecentChanges and Special:Watchlist no longer
  92   follow redirects to their target pages.
  93 * Parser now dies early if called recursively, instead of producing subtle bugs.
  94 * (bug 14323) Redirect pages, when viewed with redirect=no, no longer hide the
  95   remaining page content.
  96 * (bug 52587) Maintenance script deleteBatch.php no longer follows redirects
  97   in the file namespace and delete the file on the target page. It will still
  98   however delete the redirect page.
  99
 100 === Web API changes in 1.24 ===
 101 * action=parse API now supports prop=modules, which provides the list of
 102   ResourceLoader modules that should be used to enhance the parsed content.
 103 * action=query&meta=siteinfo&siprop=interwikimap returns a new "protorel"
 104   field which is true iff protocol-relative urls can be used to access
 105   a particular interwiki map entry.
 106 * ApiQueryLogEvents now provides logpage, which is the page ID from the
 107   logging table, if ids are requested and the user has the permissions.
 108 * action=edit now requires that appendtext, prependtext, or section=new be used
 109   when using the 'redirect' parameter, to prevent clients accidentally
 110   overwriting the target page with the content of the redirect.
 111 * action=logevents will now return an error if both letitle and leprefix are
 112   specified.
 113 * action=logevents has a new parameter, lenamespace, to allow filtering by
 114   namespace.
 115 * action=expandtemplates has a new parameter, prop, and a new output format.
 116   The old format is still used if prop isn't provided, but this is deprecated.
 117 * meta=userinfo can now return the count of unread pages on the watchlist.
 118 * list=watchlist can now filter by unread status.
 119
 120 === Languages updated in 1.24 ===
 121
 122 MediaWiki supports over 350 languages. Many localisations are updated
 123 regularly. Below only new and removed languages are listed, as well as
 124 changes to languages because of Bugzilla reports.
 125
 126 === Other changes in 1.24 ===
 127 * The deprecated jquery.delayedBind ResourceLoader module was removed.
 128 * The deprecated function mw.util.toggleToc was removed.
 129 * The Special:Search hooks SpecialSearchGo and SpecialSearchResultsAppend
 130   were removed as they were unused.
 131 * (bug 65477) User::pingLimiter() now has an additional profile point varying
 132   by action being used.
 133 * mediawiki.util.$content no longer supports old versions of the Vector,
 134   Monobook, Modern and CologneBlue skins that don't yet implement the "mw-body"
 135   and/or "mw-body-primary" class name in their html.
 136 * Added pp_sortkey column to page_props table, so pages can be efficiently
 137   queried and sorted by property value (bug 58032).
 138   See $wgPagePropsHaveSortkey if you want to postpone the schema change.
 139 * BREAKING CHANGE: The Modern and Cologne Blue skins were moved out of MediaWiki
 140   core to their own respective repositories. See also
 141   https://www.mediawiki.org/wiki/Skin:Modern and
 142   https://www.mediawiki.org/wiki/Skin:CologneBlue.
 143 * BREAKING CHANGE: Skins built for MediaWiki 1.15 and earlier that do not use
 144   the "headelement" template key are no longer supported. Setting
 145   $useHeadElement = false; is no longer supported and will not cause old keys
 146   like "headlinks", "skinnameclass", etc. to be defined.
 147 * The deprecated 'SpecialVersionExtensionTypes' hook was removed.
 148 * (bug 63891) Add 'X-Robots-Tag: noindex' header in action=render pages.
 149 * SpecialPage no longer supports the syntax for invoking wfSpecial*() functions.
 150   Special pages should subclass SpecialPage and implement the execute() method.
 151 * (bug 63755) The deprecated constants RC_MOVE and RC_MOVE_OVER_REDIRECT were
 152   removed.
 153 * Special:MostLinkedTemplates has been renamed to Special:MostTranscludedPages.
 154 * The skin autodiscovery mechanism has been deprecated and will be removed in
 155   MediaWiki 1.25. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery
 156   for migration guide for creators and users of custom skins that relied on it.

 199 == Compatibility ==
 200
 201 MediaWiki 1.24 requires PHP 5.3.2 or later.
 202
 203 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 204 support for them is somewhat less mature. There is experimental support for
 205 Oracle and Microsoft SQL Server.
 206
 207 The supported versions are:
 208
 209 * MySQL 5.0.2 or later
 210 * PostgreSQL 8.3 or later
 211 * SQLite 3.3.7 or later
 212 * Oracle 9.0.1 or later
 213 * Microsoft SQL Server 2005 (9.00.1399)
 214
 215 == Upgrading ==
 216
 217 1.24 has several database changes since 1.23, and will not work without schema
 218 updates. Note that due to changes to some very large tables like the revision
 219 table, the schema update may take quite long (minutes on a medium sized site,
 220 many hours on a large site).
 221
 222 If upgrading from before 1.11, and you are using a wiki as a commons
 223 repository, make sure that it is updated as well. Otherwise, errors may arise
 224 due to database schema changes.
 225
 226 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 227 new database fields are filled with data.
 228
 229 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 230 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 231 with MediaWiki 1.21.
 232
 233 Don't forget to always back up your database before upgrading!
 234
 235 See the file UPGRADE for more detailed upgrade instructions.
 236
 237 For notes on 1.23.x and older releases, see HISTORY.
 238
 239 == Online documentation ==
 240
 241 Documentation for both end-users and site administrators is available on
 242 MediaWiki.org, and is covered under the GNU Free Documentation License (except
 243 for pages that explicitly state that their contents are in the public domain):
 244
 245         https://www.mediawiki.org/wiki/Documentation
 246
 247 == Mailing list ==
 248
 249 A mailing list is available for MediaWiki user support and discussion:
 250
 251         https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 252
 253 A low-traffic announcements-only list is also available:
