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 * (bug 63903) Thumbnails without an explicit size specification are
  42   now resized to a square bounding box. This gives better results for
  43   non-landscape thumbnails.
  44
  45 === Bug fixes in 1.24 ===
  46 * (bug 49116) Footer copyright notice is now always displayed in user language
  47   rather than content language (same as copyright notice for editing interface).
  48 * (bug 62258) A bug was fixed in File::getUnscaledThumb when a height
  49   restriction was present in the parameters.  Images with both the "frame"
  50   option and a size specification set will now always ignore the provided
  51   size and display an unscaled image, as the documentation has always
  52   claimed it would.
  53 * (bug 39035) Improved Vector skin performance by removing collapsibleNav,
  54   which used to collapse some sidebar elements by default.
  55   This removes -list id suffixes like p-lang-list: instead of using things like
  56   #p-lang-list, you can do #p-lang .body ul.
  57 * (bug 890) Links in Special:RecentChanges and Special:Watchlist no longer
  58   follow redirects to their target pages.
  59 * Parser now dies early if called recursively, instead of producing subtle bugs.
  60 * (bug 14323) Redirect pages, when viewed with redirect=no, no longer hide the
  61   remaining page content.
  62
  63 === Web API changes in 1.24 ===
  64 * action=parse API now supports prop=modules, which provides the list of
  65   ResourceLoader modules that should be used to enhance the parsed content.
  66 * action=query&meta=siteinfo&siprop=interwikimap returns a new "protorel"
  67   field which is true iff protocol-relative urls can be used to access
  68   a particular interwiki map entry.
  69
  70 === Languages updated in 1.24 ===
  71
  72 MediaWiki supports over 350 languages. Many localisations are updated
  73 regularly. Below only new and removed languages are listed, as well as
  74 changes to languages because of Bugzilla reports.
  75
  76 === Other changes in 1.24 ===
  77 * The deprecated jquery.delayedBind ResourceLoader module was removed.
  78 * The deprecated function mw.util.toggleToc was removed.
  79 * The Special:Search hooks SpecialSearchGo and SpecialSearchResultsAppend
  80   were removed as they were unused.
  81 * (bug 65477) User::pingLimiter() now has an additional profile point varying
  82   by action being used.
  83 * mediawiki.util.$content no longer supports old versions of the Vector,
  84   Monobook, Modern and CologneBlue skins that don't yet implement the "mw-body"
  85   and/or "mw-body-primary" class name in their html.
  86 * Added pp_sortkey column to page_props table, so pages can be efficiently
  87   queried and sorted by property value (bug 58032).
  88   See $wgPagePropsHaveSortkey if you want to postpone the schema change.

 131 == Compatibility ==
 132
 133 MediaWiki 1.24 requires PHP 5.3.2 or later.
 134
 135 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 136 support for them is somewhat less mature. There is experimental support for
 137 Oracle and Microsoft SQL Server.
 138
 139 The supported versions are:
 140
 141 * MySQL 5.0.2 or later
 142 * PostgreSQL 8.3 or later
 143 * SQLite 3.3.7 or later
 144 * Oracle 9.0.1 or later
 145 * Microsoft SQL Server 2005 (9.00.1399)
 146
 147 == Upgrading ==
 148
 149 1.24 has several database changes since 1.23, and will not work without schema
 150 updates. Note that due to changes to some very large tables like the revision
 151 table, the schema update may take quite long (minutes on a medium sized site,
 152 many hours on a large site).
 153
 154 If upgrading from before 1.11, and you are using a wiki as a commons
 155 repository, make sure that it is updated as well. Otherwise, errors may arise
 156 due to database schema changes.
 157
 158 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 159 new database fields are filled with data.
 160
 161 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 162 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 163 with MediaWiki 1.21.
 164
 165 Don't forget to always back up your database before upgrading!
 166
 167 See the file UPGRADE for more detailed upgrade instructions.
 168
 169 For notes on 1.22.x and older releases, see HISTORY.
 170
 171 == Online documentation ==
 172
 173 Documentation for both end-users and site administrators is available on
 174 MediaWiki.org, and is covered under the GNU Free Documentation License (except
 175 for pages that explicitly state that their contents are in the public domain):
 176
 177         https://www.mediawiki.org/wiki/Documentation
 178
 179 == Mailing list ==
 180
 181 A mailing list is available for MediaWiki user support and discussion:
 182
 183         https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 184
 185 A low-traffic announcements-only list is also available:
 186
 187         https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 188
 189 It's highly recommended that you sign up for one of these lists if you're
 190 going to run a public MediaWiki, so you can be notified of security fixes.
 191
 192 == IRC help ==
 193
 194 There's usually someone online in #mediawiki on irc.freenode.net.
