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
  18 === New features in 1.24 ===
  19 * Added a new hook, "WhatLinksHereProps", to allow extensions to annotate
  20   WhatLinksHere entries.
  21 * Added a new hook, "ContentGetParserOutput", to customize parser output for
  22   a given content object.
  23 * Deprecated the hook "ShowRawCssJs", use "ContentGetParserOutput" instead.
  24 * HTMLForm's HTMLTextField now supports the 'url' type.
  25 * HTMLForm fields may now be dynamically hidden based on the values of other
  26   fields in the form.
  27 * HTMLForm now supports multiple copies of an input field or set of input
  28   fields, e.g. the form may request "one or more usernames" without having to
  29   have the user enter delimited list of names into a text field.
  30 * Added a new hook, "SidebarBeforeOutput", to allow to edit the structure of
  31   the sidebar just before its display.
  32 * (bug 49156) Added the mediawiki.cookie ResourceLoader module, which wraps
  33   jQuery.cookie so that getting/setting a cookie is syntactically and functionally
  34   similar to using the WebRequest#getCookie/WebResponse#setcookie methods.
  35 * (bug 44740) jQuery upgraded from 1.8.3 to 1.11.1.
  36 * Changes to content typography (fonts, etc.). See
  37   https://www.mediawiki.org/wiki/Typography_refresh for further information.
  38 * WikitextContent will now render redirects with the expected "redirect"
  39   header, rather than as an ordered list. Code calling Article::viewRedirect
  40   can probably be changed to no longer special-case redirects.
  41 * Header font set to a serif font stack. See
  42   https://www.mediawiki.org/wiki/Typography_refresh for further information.
  43 * (bug 63903) Thumbnails without an explicit size specification are
  44   now resized to a square bounding box. This gives better results for
  45   non-landscape thumbnails.
  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
  51 === Bug fixes in 1.24 ===
  52 * (bug 49116) Footer copyright notice is now always displayed in user language
  53   rather than content language (same as copyright notice for editing interface).
  54 * (bug 62258) A bug was fixed in File::getUnscaledThumb when a height
  55   restriction was present in the parameters.  Images with both the "frame"
  56   option and a size specification set will now always ignore the provided
  57   size and display an unscaled image, as the documentation has always
  58   claimed it would.
  59 * (bug 39035) Improved Vector skin performance by removing collapsibleNav,
  60   which used to collapse some sidebar elements by default.
  61   This removes -list id suffixes like p-lang-list: instead of using things like
  62   #p-lang-list, you can do #p-lang .body ul.
  63 * (bug 890) Links in Special:RecentChanges and Special:Watchlist no longer
  64   follow redirects to their target pages.
  65 * Parser now dies early if called recursively, instead of producing subtle bugs.
  66 * (bug 14323) Redirect pages, when viewed with redirect=no, no longer hide the
  67   remaining page content.
  68 * (bug 52587) Maintenance script deleteBatch.php no longer follows redirects
  69   in the file namespace and delete the file on the target page. It will still
  70   however delete the redirect page.
  71
  72 === Web API changes in 1.24 ===
  73 * action=parse API now supports prop=modules, which provides the list of
  74   ResourceLoader modules that should be used to enhance the parsed content.
  75 * action=query&meta=siteinfo&siprop=interwikimap returns a new "protorel"
  76   field which is true iff protocol-relative urls can be used to access
  77   a particular interwiki map entry.
  78 * ApiQueryLogEvents now provides logpage, which is the page ID from the
  79   logging table, if ids are requested and the user has the permissions.
  80 * action=edit now requires that appendtext, prependtext, or section=new be used
  81   when using the 'redirect' parameter, to prevent clients accidentally
  82   overwriting the target page with the content of the redirect.
  83 * action=logevents will now return an error if both letitle and leprefix are
  84   specified.
  85 * action=logevents has a new parameter, lenamespace, to allow filtering by
  86   namespace.
  87
  88 === Languages updated in 1.24 ===
  89
  90 MediaWiki supports over 350 languages. Many localisations are updated
  91 regularly. Below only new and removed languages are listed, as well as
  92 changes to languages because of Bugzilla reports.
  93
  94 === Other changes in 1.24 ===
  95 * The deprecated jquery.delayedBind ResourceLoader module was removed.
  96 * The deprecated function mw.util.toggleToc was removed.
  97 * The Special:Search hooks SpecialSearchGo and SpecialSearchResultsAppend
  98   were removed as they were unused.
  99 * (bug 65477) User::pingLimiter() now has an additional profile point varying
 100   by action being used.
 101 * mediawiki.util.$content no longer supports old versions of the Vector,
 102   Monobook, Modern and CologneBlue skins that don't yet implement the "mw-body"
 103   and/or "mw-body-primary" class name in their html.
 104 * Added pp_sortkey column to page_props table, so pages can be efficiently
 105   queried and sorted by property value (bug 58032).
 106   See $wgPagePropsHaveSortkey if you want to postpone the schema change.
 107 * BREAKING CHANGE: The Modern and Cologne Blue skins were moved out of MediaWiki
 108   core to their own respective repositories. See also
 109   https://www.mediawiki.org/wiki/Skin:Modern and
 110   https://www.mediawiki.org/wiki/Skin:CologneBlue.

 153 == Compatibility ==
 154
 155 MediaWiki 1.24 requires PHP 5.3.2 or later.
 156
 157 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 158 support for them is somewhat less mature. There is experimental support for
 159 Oracle and Microsoft SQL Server.
 160
 161 The supported versions are:
 162
 163 * MySQL 5.0.2 or later
 164 * PostgreSQL 8.3 or later
 165 * SQLite 3.3.7 or later
 166 * Oracle 9.0.1 or later
 167 * Microsoft SQL Server 2005 (9.00.1399)
 168
 169 == Upgrading ==
 170
 171 1.24 has several database changes since 1.23, and will not work without schema
 172 updates. Note that due to changes to some very large tables like the revision
 173 table, the schema update may take quite long (minutes on a medium sized site,
 174 many hours on a large site).
 175
 176 If upgrading from before 1.11, and you are using a wiki as a commons
 177 repository, make sure that it is updated as well. Otherwise, errors may arise
 178 due to database schema changes.
 179
 180 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 181 new database fields are filled with data.
 182
 183 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 184 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 185 with MediaWiki 1.21.
 186
 187 Don't forget to always back up your database before upgrading!
 188
 189 See the file UPGRADE for more detailed upgrade instructions.
 190
 191 For notes on 1.22.x and older releases, see HISTORY.
 192
 193 == Online documentation ==
 194
 195 Documentation for both end-users and site administrators is available on
 196 MediaWiki.org, and is covered under the GNU Free Documentation License (except
 197 for pages that explicitly state that their contents are in the public domain):
 198
 199         https://www.mediawiki.org/wiki/Documentation
 200
 201 == Mailing list ==
 202
 203 A mailing list is available for MediaWiki user support and discussion:
 204
 205         https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 206
 207 A low-traffic announcements-only list is also available:
 208
 209         https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 210
 211 It's highly recommended that you sign up for one of these lists if you're
 212 going to run a public MediaWiki, so you can be notified of security fixes.
 213
 214 == IRC help ==
 215
 216 There's usually someone online in #mediawiki on irc.freenode.net.
