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 * $wgParserTestRemote has been removed.
  29
  30 === New features in 1.24 ===
  31 * Added a new hook, "WhatLinksHereProps", to allow extensions to annotate
  32   WhatLinksHere entries.
  33 * Added a new hook, "ContentGetParserOutput", to customize parser output for
  34   a given content object.
  35 * Deprecated the hook "ShowRawCssJs", use "ContentGetParserOutput" instead.
  36 * HTMLForm's HTMLTextField now supports the 'url' type.
  37 * HTMLForm fields may now be dynamically hidden based on the values of other
  38   fields in the form.
  39 * HTMLForm now supports multiple copies of an input field or set of input
  40   fields, e.g. the form may request "one or more usernames" without having to
  41   have the user enter delimited list of names into a text field.
  42 * Added a new hook, "SidebarBeforeOutput", to allow to edit the structure of
  43   the sidebar just before its display.
  44 * (bug 49156) Added the mediawiki.cookie ResourceLoader module, which wraps
  45   jquery.cookie so that getting/setting a cookie is syntactically and
  46   functionally similar to using the WebRequest::getCookie() and
  47   WebResponse::setcookie() methods.
  48 * (bug 44740) jQuery upgraded from 1.8.3 to 1.11.1. A new configuration option,
  49   $wgIncludejQueryMigrate, also loads the jQuery Migrate hack to let extensions
  50   and gadgets use the long-deprecated functions that were removed in jQuery 1.9.
  51   This option is turned off by default, and will be removed in MediaWiki 1.25.
  52 * (bug 47076) jQuery UI upgraded from 1.8.24 to 1.9.2.
  53 * Changes to content typography (fonts, etc.). See
  54   https://www.mediawiki.org/wiki/Typography_refresh for further information.
  55 * WikitextContent will now render redirects with the expected "redirect"
  56   header, rather than as an ordered list. Code calling Article::viewRedirect
  57   can probably be changed to no longer special-case redirects.
  58 * Header font set to a serif font stack. See
  59   https://www.mediawiki.org/wiki/Typography_refresh for further information.
  60 * (bug 65567) Added a new hook, "BeforeHttpsRedirect", to allow cancellation of
  61   the HTTP to HTTPS redirect due to forceHTTPS cookie, userRequires, etc. This
  62   is only for page views, since this hook doesn't affect UserLogin, OAuth,
  63   CentralAuth, etc. ATTENTION: This hook is likely to be removed soon due to
  64   overall design of the system.
  65 * (bug 17367) It is now possible to add pages to your watchlist from
  66   Special:UnwatchedPages without reloading the special page.
  67 * New methods setVolatile and isVolatile are added to PPFrame, so that
  68   extensions such as Cite.php can mark that their output is volatile and
  69   shouldn't be cached.
  70 * (bug 52817) Advanced search options are now saved on the search page itself,
  71   rather than in a dedicated pane in the preferences panel.
  72 * (bug 44591) The dropdown actions menu (little triangle next to page tabs) in
  73   the Vector skin has gained a label that should make it more discoverable.
  74 * MWCryptHKDF added for fast, cryptographically secure random number generation
  75   that won't deplete openssl's entropy pool.
  76 * ResourceLoader: File modules can now provide a skip function that uses an
  77   inline feature test to bypass loading of the module.
  78 * (bug 20210) Special pages may now provide autocompletion of their subpage
  79   names in search suggestions. Right now the only useful implementation is in
  80   Special:Log, but more are to come.
  81 * Special:MostLinkedTemplates is no longer limited to transclusions from the
  82   Template namespace.
  83 * Skins can now use 'remoteSkinPath' when defining ResourceLoader modules.
  84   This works the same as 'remoteExtPath' but is relative to the skins/ folder
  85   instead of the extensions/ folder.
  86 * Added the json2.js polyfill for the ES5 JSON.stringify and JSON.parse methods.
  87   Exposed as module "json" with a skip function to optimise loading.
  88 * Extensions and skins may now use 'namemsg' in $wgExtensionCredits in addition
  89   to 'name', to allow for the name to be localizable. 'name' should still be
  90   specified for backwards-compatibility and to define the path Special:Version
  91   uses to find extension license information.
  92 * Browser tests are now included to verify basic wiki functionality in developer
  93   environments. For details on running tests, see tests/browser/README.mediawiki.
  94 * Upgrade jStorage to v0.4.10.
  95 * {{!}} is now a magic word that produces the | character. This removes the need
  96   for Template:! for purposes such as passing pipes inside of parameters.
  97 * (bug 20790) The block log snippet on Special:Contributions and while
  98   editing user and user talk pages now works for IP range blocks.
  99
 100 === Bug fixes in 1.24 ===
 101 * (bug 49116) Footer copyright notice is now always displayed in user language
 102   rather than content language (same as copyright notice for editing interface).
 103 * (bug 62258) A bug was fixed in File::getUnscaledThumb when a height
 104   restriction was present in the parameters. Images with both the "frame"
 105   option and a size specification set will now always ignore the provided
 106   size and display an unscaled image, as the documentation has always
 107   claimed it would.
 108 * (bug 39035) Improved Vector skin performance by removing collapsibleNav,
 109   which used to collapse some sidebar elements by default.
 110   This removes -list id suffixes like p-lang-list: instead of using things like
 111   #p-lang-list, you can do #p-lang .body ul.
 112 * (bug 890) Links in Special:RecentChanges and Special:Watchlist no longer
 113   follow redirects to their target pages.
 114 * Parser now dies early if called recursively, instead of producing subtle bugs.
 115 * (bug 14323) Redirect pages, when viewed with redirect=no, no longer hide the
 116   remaining page content.
 117 * (bug 52587) Maintenance script deleteBatch.php no longer follows redirects
 118   in the file namespace and delete the file on the target page. It will still
 119   however delete the redirect page.
 120 * (bug 22683) {{msgnw:}} and other uses of PPFrame::RECOVER_ORIG will correctly
 121   recover the original code of extension tags.
 122
 123 === Web API changes in 1.24 ===
 124 * action=parse API now supports prop=modules, which provides the list of
 125   ResourceLoader modules that should be used to enhance the parsed content.
 126 * action=query&meta=siteinfo&siprop=interwikimap returns a new "protorel"
 127   field which is true iff protocol-relative urls can be used to access
 128   a particular interwiki map entry.
 129 * ApiQueryLogEvents now provides logpage, which is the page ID from the
 130   logging table, if ids are requested and the user has the permissions.
 131 * action=edit now requires that appendtext, prependtext, or section=new be used
 132   when using the 'redirect' parameter, to prevent clients accidentally
 133   overwriting the target page with the content of the redirect.
 134 * action=logevents will now return an error if both letitle and leprefix are
 135   specified.
 136 * action=logevents has a new parameter, lenamespace, to allow filtering by
 137   namespace.
 138 * action=expandtemplates has a new parameter, prop, and a new output format.
 139   The old format is still used if prop isn't provided, but this is deprecated.
 140 * meta=userinfo can now return the count of unread pages on the watchlist.
 141 * list=watchlist can now filter by unread status.
 142
 143 === Languages updated in 1.24 ===
 144
 145 MediaWiki supports over 350 languages. Many localisations are updated
 146 regularly. Below only new and removed languages are listed, as well as
 147 changes to languages because of Bugzilla reports.
 148
 149 === Other changes in 1.24 ===
 150 * The deprecated jquery.delayedBind ResourceLoader module was removed.
 151 * The deprecated function mw.util.toggleToc was removed.
 152 * The Special:Search hooks SpecialSearchGo and SpecialSearchResultsAppend
 153   were removed as they were unused.
 154 * (bug 65477) User::pingLimiter() now has an additional profile point varying
 155   by action being used.
 156 * mediawiki.util.$content no longer supports old versions of the Vector,
 157   Monobook, Modern and CologneBlue skins that don't yet implement the "mw-body"
 158   and/or "mw-body-primary" class name in their html.
 159 * Added pp_sortkey column to page_props table, so pages can be efficiently
 160   queried and sorted by property value (bug 58032).
 161   See $wgPagePropsHaveSortkey if you want to postpone the schema change.
 162 * BREAKING CHANGE: The Modern and Cologne Blue skins were moved out of MediaWiki
 163   core to their own respective repositories. See also
 164   https://www.mediawiki.org/wiki/Skin:Modern and
 165   https://www.mediawiki.org/wiki/Skin:CologneBlue.
 166 * BREAKING CHANGE: Skins built for MediaWiki 1.15 and earlier that do not use
 167   the "headelement" template key are no longer supported. Setting
 168   $useHeadElement = false; is no longer supported and will not cause old keys
 169   like "headlinks", "skinnameclass", etc. to be defined.
 170 * The deprecated 'SpecialVersionExtensionTypes' hook was removed.
 171 * (bug 63891) Add 'X-Robots-Tag: noindex' header in action=render pages.
 172 * SpecialPage no longer supports the syntax for invoking wfSpecial*() functions.
 173   Special pages should subclass SpecialPage and implement the execute() method.
 174 * (bug 63755) The deprecated constants RC_MOVE and RC_MOVE_OVER_REDIRECT were
 175   removed.
 176 * Special:MostLinkedTemplates has been renamed to Special:MostTranscludedPages.
 177 * The skin autodiscovery mechanism has been deprecated and will be removed in
 178   MediaWiki 1.25. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery
 179   for migration guide for creators and users of custom skins that relied on it.
 180 * ResourceLoaderFileModule#getAllStyleFiles now returns all style files and all
 181   skin style files used by the module.
 182 * Removed getLang() from IContextSource and subclasses. (deprecated since 1.19)
 183 * Removed setLang() from subclasses of IContextSource. (deprecated since 1.19)
 184 * Removed WebRequest::escapeAppendQuery(). (deprecated since 1.20)
 185 * Removed info(), purge(), revert() and rollback() from the Article class; they
 186   have since become subclasses of the Action class. (deprecated since 1.19)
 187 * SearchEngineReplacePrefixesComplete hook was removed.
 188 * The "jquery.json" module has been deprecated. Use the "json" module instead.
 189 * Removed HTMLForm::addJS(). (deprecated since 1.18)
 190 * Removed LogEventsList::showHeader(). (deprecated since 1.19)
 191 * Removed ImageGalleryBase::useSkin(). (deprecated since 1.18)
 192 * Removed DatabaseMysqlBase::getLagFromProcesslist(). (deprecated since 1.19)
 193 * Removed LoadBalancer::closeConnecton(). (deprecated since 1.18)

 238 == Compatibility ==
 239
 240 MediaWiki 1.24 requires PHP 5.3.2 or later.
 241
 242 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 243 support for them is somewhat less mature. There is experimental support for
 244 Oracle and Microsoft SQL Server.
 245
 246 The supported versions are:
 247
 248 * MySQL 5.0.2 or later
 249 * PostgreSQL 8.3 or later
 250 * SQLite 3.3.7 or later
 251 * Oracle 9.0.1 or later
 252 * Microsoft SQL Server 2005 (9.00.1399)
 253
 254 == Upgrading ==
 255
 256 1.24 has several database changes since 1.23, and will not work without schema
 257 updates. Note that due to changes to some very large tables like the revision
 258 table, the schema update may take quite long (minutes on a medium sized site,
 259 many hours on a large site).
 260
 261 If upgrading from before 1.11, and you are using a wiki as a commons
 262 repository, make sure that it is updated as well. Otherwise, errors may arise
 263 due to database schema changes.
 264
 265 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 266 new database fields are filled with data.
 267
 268 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 269 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 270 with MediaWiki 1.21.
 271
 272 Don't forget to always back up your database before upgrading!
 273
 274 See the file UPGRADE for more detailed upgrade instructions.
 275
 276 For notes on 1.23.x and older releases, see HISTORY.
 277
 278 == Online documentation ==
 279
 280 Documentation for both end-users and site administrators is available on
 281 MediaWiki.org, and is covered under the GNU Free Documentation License (except
 282 for pages that explicitly state that their contents are in the public domain):
 283
 284         https://www.mediawiki.org/wiki/Documentation
 285
 286 == Mailing list ==
 287
 288 A mailing list is available for MediaWiki user support and discussion:
 289
 290         https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 291
 292 A low-traffic announcements-only list is also available:
 293
 294         https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 295
 296 It's highly recommended that you sign up for one of these lists if you're
 297 going to run a public MediaWiki, so you can be notified of security fixes.
 298
 299 == IRC help ==
