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 * $wgExtraInterlanguageLinkPrefixes is a new configuration variable that
  25   contains an array of interwiki prefixes that should be treated as language
  26   prefixes (i.e. turned into interlanguage links when $wgInterwikiMagic is set
  27   to true).
  28
  29 === New features in 1.24 ===
  30 * Added a new hook, "WhatLinksHereProps", to allow extensions to annotate
  31   WhatLinksHere entries.
  32 * Added a new hook, "ContentGetParserOutput", to customize parser output for
  33   a given content object.
  34 * Deprecated the hook "ShowRawCssJs", use "ContentGetParserOutput" instead.
  35 * HTMLForm's HTMLTextField now supports the 'url' type.
  36 * HTMLForm fields may now be dynamically hidden based on the values of other
  37   fields in the form.
  38 * HTMLForm now supports multiple copies of an input field or set of input
  39   fields, e.g. the form may request "one or more usernames" without having to
  40   have the user enter delimited list of names into a text field.
  41 * Added a new hook, "SidebarBeforeOutput", to allow to edit the structure of
  42   the sidebar just before its display.
  43 * (bug 49156) Added the mediawiki.cookie ResourceLoader module, which wraps
  44   jquery.cookie so that getting/setting a cookie is syntactically and
  45   functionally similar to using the WebRequest::getCookie() and
  46   WebResponse::setcookie() methods.
  47 * (bug 44740) jQuery upgraded from 1.8.3 to 1.11.1. A new configuration option,
  48   $wgIncludejQueryMigrate, also loads the jQuery Migrate hack to let extensions
  49   and gadgets use the long-deprecated functions that were removed in jQuery 1.9.
  50   This option is turned off by default, and will be removed in MediaWiki 1.25.
  51 * (bug 47076) jQuery UI upgraded from 1.8.24 to 1.9.2.
  52 * Changes to content typography (fonts, etc.). See
  53   https://www.mediawiki.org/wiki/Typography_refresh for further information.
  54 * WikitextContent will now render redirects with the expected "redirect"
  55   header, rather than as an ordered list. Code calling Article::viewRedirect
  56   can probably be changed to no longer special-case redirects.
  57 * Header font set to a serif font stack. See
  58   https://www.mediawiki.org/wiki/Typography_refresh for further information.
  59 * (bug 65567) Added a new hook, "BeforeHttpsRedirect", to allow cancellation of
  60   the HTTP to HTTPS redirect due to forceHTTPS cookie, userRequires, etc. This
  61   is only for page views, since this hook doesn't affect UserLogin, OAuth,
  62   CentralAuth, etc. ATTENTION: This hook is likely to be removed soon due to
  63   overall design of the system.
  64 * (bug 17367) It is now possible to add pages to your watchlist from
  65   Special:UnwatchedPages without reloading the special page.
  66 * New methods setVolatile and isVolatile are added to PPFrame, so that
  67   extensions such as Cite.php can mark that their output is volatile and
  68   shouldn't be cached.
  69 * (bug 52817) Advanced search options are now saved on the search page itself,
  70   rather than in a dedicated pane in the preferences panel.
  71 * (bug 44591) The dropdown actions menu (little triangle next to page tabs) in
  72   the Vector skin has gained a label that should make it more discoverable.
  73 * MWCryptHKDF added for fast, cryptographically secure random number generation
  74   that won't deplete openssl's entropy pool.
  75 * ResourceLoader: File modules can now provide a skip function that uses an
  76   inline feature test to bypass loading of the module.
  77 * (bug 20210) Special pages may now provide autocompletion of their subpage
  78   names in search suggestions. Right now the only useful implementation is in
  79   Special:Log, but more are to come.
  80 * Special:MostLinkedTemplates is no longer limited to transclusions from the
  81   Template namespace.
  82 * Skins can now use 'remoteSkinPath' when defining ResourceLoader modules.
  83   This works the same as 'remoteExtPath' but is relative to the skins/ folder
  84   instead of the extensions/ folder.
  85 * Extensions and skins may now use 'namemsg' in $wgExtensionCredits in addition
  86   to 'name', to allow for the name to be localizable. 'name' should still be
  87   specified for backwards-compatibility and to define the path Special:Version
  88   uses to find extension license information.
  89
  90 === Bug fixes in 1.24 ===
  91 * (bug 49116) Footer copyright notice is now always displayed in user language
  92   rather than content language (same as copyright notice for editing interface).
  93 * (bug 62258) A bug was fixed in File::getUnscaledThumb when a height
  94   restriction was present in the parameters. Images with both the "frame"
  95   option and a size specification set will now always ignore the provided
  96   size and display an unscaled image, as the documentation has always
  97   claimed it would.
  98 * (bug 39035) Improved Vector skin performance by removing collapsibleNav,
  99   which used to collapse some sidebar elements by default.
 100   This removes -list id suffixes like p-lang-list: instead of using things like
 101   #p-lang-list, you can do #p-lang .body ul.
 102 * (bug 890) Links in Special:RecentChanges and Special:Watchlist no longer
 103   follow redirects to their target pages.
 104 * Parser now dies early if called recursively, instead of producing subtle bugs.
 105 * (bug 14323) Redirect pages, when viewed with redirect=no, no longer hide the
 106   remaining page content.
 107 * (bug 52587) Maintenance script deleteBatch.php no longer follows redirects
 108   in the file namespace and delete the file on the target page. It will still
 109   however delete the redirect page.
 110 * (bug 22683) {{msgnw:}} and other uses of PPFrame::RECOVER_ORIG will correctly
 111   recover the original code of extension tags.
 112
 113 === Web API changes in 1.24 ===
 114 * action=parse API now supports prop=modules, which provides the list of
 115   ResourceLoader modules that should be used to enhance the parsed content.
 116 * action=query&meta=siteinfo&siprop=interwikimap returns a new "protorel"
 117   field which is true iff protocol-relative urls can be used to access
 118   a particular interwiki map entry.
 119 * ApiQueryLogEvents now provides logpage, which is the page ID from the
 120   logging table, if ids are requested and the user has the permissions.
 121 * action=edit now requires that appendtext, prependtext, or section=new be used
 122   when using the 'redirect' parameter, to prevent clients accidentally
 123   overwriting the target page with the content of the redirect.
 124 * action=logevents will now return an error if both letitle and leprefix are
 125   specified.
 126 * action=logevents has a new parameter, lenamespace, to allow filtering by
 127   namespace.
 128 * action=expandtemplates has a new parameter, prop, and a new output format.
 129   The old format is still used if prop isn't provided, but this is deprecated.
 130 * meta=userinfo can now return the count of unread pages on the watchlist.
 131 * list=watchlist can now filter by unread status.
 132
 133 === Languages updated in 1.24 ===
 134
 135 MediaWiki supports over 350 languages. Many localisations are updated
 136 regularly. Below only new and removed languages are listed, as well as
 137 changes to languages because of Bugzilla reports.
 138
 139 === Other changes in 1.24 ===
 140 * The deprecated jquery.delayedBind ResourceLoader module was removed.
 141 * The deprecated function mw.util.toggleToc was removed.
 142 * The Special:Search hooks SpecialSearchGo and SpecialSearchResultsAppend
 143   were removed as they were unused.
 144 * (bug 65477) User::pingLimiter() now has an additional profile point varying
 145   by action being used.
 146 * mediawiki.util.$content no longer supports old versions of the Vector,
 147   Monobook, Modern and CologneBlue skins that don't yet implement the "mw-body"
 148   and/or "mw-body-primary" class name in their html.
 149 * Added pp_sortkey column to page_props table, so pages can be efficiently
 150   queried and sorted by property value (bug 58032).
 151   See $wgPagePropsHaveSortkey if you want to postpone the schema change.
 152 * BREAKING CHANGE: The Modern and Cologne Blue skins were moved out of MediaWiki
 153   core to their own respective repositories. See also
 154   https://www.mediawiki.org/wiki/Skin:Modern and
 155   https://www.mediawiki.org/wiki/Skin:CologneBlue.
 156 * BREAKING CHANGE: Skins built for MediaWiki 1.15 and earlier that do not use
 157   the "headelement" template key are no longer supported. Setting
 158   $useHeadElement = false; is no longer supported and will not cause old keys
 159   like "headlinks", "skinnameclass", etc. to be defined.
 160 * The deprecated 'SpecialVersionExtensionTypes' hook was removed.
 161 * (bug 63891) Add 'X-Robots-Tag: noindex' header in action=render pages.
 162 * SpecialPage no longer supports the syntax for invoking wfSpecial*() functions.
 163   Special pages should subclass SpecialPage and implement the execute() method.
 164 * (bug 63755) The deprecated constants RC_MOVE and RC_MOVE_OVER_REDIRECT were
 165   removed.
 166 * Special:MostLinkedTemplates has been renamed to Special:MostTranscludedPages.
 167 * The skin autodiscovery mechanism has been deprecated and will be removed in
 168   MediaWiki 1.25. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery
 169   for migration guide for creators and users of custom skins that relied on it.
 170 * ResourceLoaderFileModule#getAllStyleFiles now returns all style files and all
 171   skin style files used by the module.
 172 * Removed getLang() from IContextSource and subclasses. (deprecated since 1.19)
 173 * Removed setLang() from subclasses of IContextSource. (deprecated since 1.19)
 174 * Removed WebRequest::escapeAppendQuery(). (deprecated since 1.20)
 175 * Removed info(), purge(), revert() and rollback() from the Article class; they
 176   have since become subclasses of the Action class. (deprecated since 1.19)

 219 == Compatibility ==
 220
 221 MediaWiki 1.24 requires PHP 5.3.2 or later.
 222
 223 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 224 support for them is somewhat less mature. There is experimental support for
 225 Oracle and Microsoft SQL Server.
 226
 227 The supported versions are:
 228
 229 * MySQL 5.0.2 or later
 230 * PostgreSQL 8.3 or later
 231 * SQLite 3.3.7 or later
 232 * Oracle 9.0.1 or later
 233 * Microsoft SQL Server 2005 (9.00.1399)
 234
 235 == Upgrading ==
 236
 237 1.24 has several database changes since 1.23, and will not work without schema
 238 updates. Note that due to changes to some very large tables like the revision
 239 table, the schema update may take quite long (minutes on a medium sized site,
 240 many hours on a large site).
 241
 242 If upgrading from before 1.11, and you are using a wiki as a commons
 243 repository, make sure that it is updated as well. Otherwise, errors may arise
 244 due to database schema changes.
 245
 246 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 247 new database fields are filled with data.
 248
 249 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 250 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 251 with MediaWiki 1.21.
 252
 253 Don't forget to always back up your database before upgrading!
 254
 255 See the file UPGRADE for more detailed upgrade instructions.
 256
 257 For notes on 1.23.x and older releases, see HISTORY.
 258
 259 == Online documentation ==

 265         https://www.mediawiki.org/wiki/Documentation
 266
 267 == Mailing list ==
 268
 269 A mailing list is available for MediaWiki user support and discussion:
 270
 271         https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 272
