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 * Skins can now use 'remoteSkinPath' when defining ResourceLoader modules.
  79   This works the same as 'remoteExtPath' but is relative to the skins/ folder
  80   instead of the extensions/ folder.
  81
  82 === Bug fixes in 1.24 ===
  83 * (bug 49116) Footer copyright notice is now always displayed in user language
  84   rather than content language (same as copyright notice for editing interface).
  85 * (bug 62258) A bug was fixed in File::getUnscaledThumb when a height
  86   restriction was present in the parameters. Images with both the "frame"
  87   option and a size specification set will now always ignore the provided
  88   size and display an unscaled image, as the documentation has always
  89   claimed it would.
  90 * (bug 39035) Improved Vector skin performance by removing collapsibleNav,
  91   which used to collapse some sidebar elements by default.
  92   This removes -list id suffixes like p-lang-list: instead of using things like
  93   #p-lang-list, you can do #p-lang .body ul.
  94 * (bug 890) Links in Special:RecentChanges and Special:Watchlist no longer
  95   follow redirects to their target pages.
  96 * Parser now dies early if called recursively, instead of producing subtle bugs.
  97 * (bug 14323) Redirect pages, when viewed with redirect=no, no longer hide the
  98   remaining page content.
  99 * (bug 52587) Maintenance script deleteBatch.php no longer follows redirects
 100   in the file namespace and delete the file on the target page. It will still
 101   however delete the redirect page.
 102 * (bug 22683) {{msgnw:}} and other uses of PPFrame::RECOVER_ORIG will correctly
 103   recover the original code of extension tags.
 104
 105 === Web API changes in 1.24 ===
 106 * action=parse API now supports prop=modules, which provides the list of
 107   ResourceLoader modules that should be used to enhance the parsed content.
 108 * action=query&meta=siteinfo&siprop=interwikimap returns a new "protorel"
 109   field which is true iff protocol-relative urls can be used to access
 110   a particular interwiki map entry.
 111 * ApiQueryLogEvents now provides logpage, which is the page ID from the
 112   logging table, if ids are requested and the user has the permissions.
 113 * action=edit now requires that appendtext, prependtext, or section=new be used
 114   when using the 'redirect' parameter, to prevent clients accidentally
 115   overwriting the target page with the content of the redirect.
 116 * action=logevents will now return an error if both letitle and leprefix are
 117   specified.
 118 * action=logevents has a new parameter, lenamespace, to allow filtering by
 119   namespace.
 120 * action=expandtemplates has a new parameter, prop, and a new output format.
 121   The old format is still used if prop isn't provided, but this is deprecated.
 122 * meta=userinfo can now return the count of unread pages on the watchlist.
 123 * list=watchlist can now filter by unread status.
 124
 125 === Languages updated in 1.24 ===
 126
 127 MediaWiki supports over 350 languages. Many localisations are updated
 128 regularly. Below only new and removed languages are listed, as well as
 129 changes to languages because of Bugzilla reports.
 130
 131 === Other changes in 1.24 ===
 132 * The deprecated jquery.delayedBind ResourceLoader module was removed.
 133 * The deprecated function mw.util.toggleToc was removed.
 134 * The Special:Search hooks SpecialSearchGo and SpecialSearchResultsAppend
 135   were removed as they were unused.
 136 * (bug 65477) User::pingLimiter() now has an additional profile point varying
 137   by action being used.
 138 * mediawiki.util.$content no longer supports old versions of the Vector,
 139   Monobook, Modern and CologneBlue skins that don't yet implement the "mw-body"
 140   and/or "mw-body-primary" class name in their html.
 141 * Added pp_sortkey column to page_props table, so pages can be efficiently
 142   queried and sorted by property value (bug 58032).
 143   See $wgPagePropsHaveSortkey if you want to postpone the schema change.
 144 * BREAKING CHANGE: The Modern and Cologne Blue skins were moved out of MediaWiki
 145   core to their own respective repositories. See also
 146   https://www.mediawiki.org/wiki/Skin:Modern and
 147   https://www.mediawiki.org/wiki/Skin:CologneBlue.
 148 * BREAKING CHANGE: Skins built for MediaWiki 1.15 and earlier that do not use
 149   the "headelement" template key are no longer supported. Setting
 150   $useHeadElement = false; is no longer supported and will not cause old keys
 151   like "headlinks", "skinnameclass", etc. to be defined.
 152 * The deprecated 'SpecialVersionExtensionTypes' hook was removed.
 153 * (bug 63891) Add 'X-Robots-Tag: noindex' header in action=render pages.
 154 * SpecialPage no longer supports the syntax for invoking wfSpecial*() functions.
 155   Special pages should subclass SpecialPage and implement the execute() method.
 156 * (bug 63755) The deprecated constants RC_MOVE and RC_MOVE_OVER_REDIRECT were
 157   removed.
 158 * Special:MostLinkedTemplates has been renamed to Special:MostTranscludedPages.
 159 * The skin autodiscovery mechanism has been deprecated and will be removed in
 160   MediaWiki 1.25. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery
 161   for migration guide for creators and users of custom skins that relied on it.
 162 * ResourceLoaderFileModule#getAllStyleFiles now returns all style files and all
 163   skin style files used by the module.

 206 == Compatibility ==
 207
 208 MediaWiki 1.24 requires PHP 5.3.2 or later.
 209
 210 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 211 support for them is somewhat less mature. There is experimental support for
 212 Oracle and Microsoft SQL Server.
 213
 214 The supported versions are:
 215
 216 * MySQL 5.0.2 or later
 217 * PostgreSQL 8.3 or later
 218 * SQLite 3.3.7 or later
 219 * Oracle 9.0.1 or later
 220 * Microsoft SQL Server 2005 (9.00.1399)
 221
 222 == Upgrading ==
 223
 224 1.24 has several database changes since 1.23, and will not work without schema
 225 updates. Note that due to changes to some very large tables like the revision
 226 table, the schema update may take quite long (minutes on a medium sized site,
 227 many hours on a large site).
 228
 229 If upgrading from before 1.11, and you are using a wiki as a commons
 230 repository, make sure that it is updated as well. Otherwise, errors may arise
 231 due to database schema changes.
 232
 233 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 234 new database fields are filled with data.
 235
 236 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 237 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 238 with MediaWiki 1.21.
 239
 240 Don't forget to always back up your database before upgrading!
 241
 242 See the file UPGRADE for more detailed upgrade instructions.
 243
 244 For notes on 1.23.x and older releases, see HISTORY.
