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

 167 == Compatibility ==
 168
 169 MediaWiki 1.24 requires PHP 5.3.2 or later.
 170
 171 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 172 support for them is somewhat less mature. There is experimental support for
 173 Oracle and Microsoft SQL Server.
 174
 175 The supported versions are:
 176
 177 * MySQL 5.0.2 or later
 178 * PostgreSQL 8.3 or later
 179 * SQLite 3.3.7 or later
 180 * Oracle 9.0.1 or later
 181 * Microsoft SQL Server 2005 (9.00.1399)
 182
 183 == Upgrading ==
 184
 185 1.24 has several database changes since 1.23, and will not work without schema
 186 updates. Note that due to changes to some very large tables like the revision
 187 table, the schema update may take quite long (minutes on a medium sized site,
 188 many hours on a large site).
 189
 190 If upgrading from before 1.11, and you are using a wiki as a commons
 191 repository, make sure that it is updated as well. Otherwise, errors may arise
 192 due to database schema changes.
 193
 194 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 195 new database fields are filled with data.
 196
 197 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 198 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 199 with MediaWiki 1.21.
 200
 201 Don't forget to always back up your database before upgrading!
 202
 203 See the file UPGRADE for more detailed upgrade instructions.
 204
 205 For notes on 1.22.x and older releases, see HISTORY.
 206
