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

 175 == Compatibility ==
 176
 177 MediaWiki 1.24 requires PHP 5.3.2 or later.
 178
 179 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 180 support for them is somewhat less mature. There is experimental support for
 181 Oracle and Microsoft SQL Server.
 182
 183 The supported versions are:
 184
 185 * MySQL 5.0.2 or later
 186 * PostgreSQL 8.3 or later
 187 * SQLite 3.3.7 or later
 188 * Oracle 9.0.1 or later
 189 * Microsoft SQL Server 2005 (9.00.1399)
 190
 191 == Upgrading ==
 192
 193 1.24 has several database changes since 1.23, and will not work without schema
 194 updates. Note that due to changes to some very large tables like the revision
 195 table, the schema update may take quite long (minutes on a medium sized site,
 196 many hours on a large site).
 197
 198 If upgrading from before 1.11, and you are using a wiki as a commons
 199 repository, make sure that it is updated as well. Otherwise, errors may arise
 200 due to database schema changes.
 201
 202 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 203 new database fields are filled with data.
 204
 205 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 206 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 207 with MediaWiki 1.21.
 208
 209 Don't forget to always back up your database before upgrading!
 210
 211 See the file UPGRADE for more detailed upgrade instructions.
 212
 213 For notes on 1.22.x and older releases, see HISTORY.
 214

 223 == Mailing list ==
 224
 225 A mailing list is available for MediaWiki user support and discussion:
 226
 227         https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 228
