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
  42 === Bug fixes in 1.24 ===
  43 * (bug 49116) Footer copyright notice is now always displayed in user language
  44   rather than content language (same as copyright notice for editing interface).
  45 * (bug 62258) A bug was fixed in File::getUnscaledThumb when a height
  46   restriction was present in the parameters.  Images with both the "frame"
  47   option and a size specification set will now always ignore the provided
  48   size and display an unscaled image, as the documentation has always
  49   claimed it would.
  50 * (bug 39035) Improved Vector skin performance by removing collapsibleNav,
  51   which used to collapse some sidebar elements by default.
  52 * (bug 890) Links in Special:RecentChanges and Special:Watchlist no longer
  53   follow redirects to their target pages.
  54 * Parser now dies early if called recursively, instead of producing subtle bugs.
  55 * (bug 14323) Redirect pages, when viewed with redirect=no, no longer hide the
  56   remaining page content.
  57
  58 === Web API changes in 1.24 ===
  59 * action=parse API now supports prop=modules, which provides the list of
  60   ResourceLoader modules that should be used to enhance the parsed content.
  61 * action=query&meta=siteinfo&siprop=interwikimap returns a new "protorel"
  62   field which is true iff protocol-relative urls can be used to access
  63   a particular interwiki map entry.
  64
  65 === Languages updated in 1.24 ===
  66
  67 MediaWiki supports over 350 languages. Many localisations are updated
  68 regularly. Below only new and removed languages are listed, as well as
  69 changes to languages because of Bugzilla reports.
  70
  71 === Other changes in 1.24 ===
  72 * The deprecated jquery.delayedBind ResourceLoader module was removed.
  73 * The deprecated function mw.util.toggleToc was removed.
  74 * The Special:Search hooks SpecialSearchGo and SpecialSearchResultsAppend
  75   were removed as they were unused.
  76 * (bug 65477) User::pingLimiter() now has an additional profile point varying
  77   by action being used.
  78 * mediawiki.util.$content no longer supports old versions of the Vector,
  79   Monobook, Modern and CologneBlue skins that don't yet implement the "mw-body"
  80   and/or "mw-body-primary" class name in their html.
  81 * Added pp_sortkey column to page_props table, so pages can be efficiently
  82   queried and sorted by property value (bug 58032).
  83   See $wgPagePropsHaveSortkey if you want to postpone the schema change.

 126 == Compatibility ==
 127
 128 MediaWiki 1.24 requires PHP 5.3.2 or later.
 129
 130 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 131 support for them is somewhat less mature. There is experimental support for
 132 Oracle and Microsoft SQL Server.
 133
 134 The supported versions are:
 135
 136 * MySQL 5.0.2 or later
 137 * PostgreSQL 8.3 or later
 138 * SQLite 3.3.7 or later
 139 * Oracle 9.0.1 or later
 140 * Microsoft SQL Server 2005 (9.00.1399)
 141
 142 == Upgrading ==
 143
 144 1.24 has several database changes since 1.23, and will not work without schema
 145 updates. Note that due to changes to some very large tables like the revision
 146 table, the schema update may take quite long (minutes on a medium sized site,
 147 many hours on a large site).
 148
 149 If upgrading from before 1.11, and you are using a wiki as a commons
 150 repository, make sure that it is updated as well. Otherwise, errors may arise
 151 due to database schema changes.
 152
 153 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 154 new database fields are filled with data.
 155
 156 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 157 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 158 with MediaWiki 1.21.
 159
 160 Don't forget to always back up your database before upgrading!
 161
 162 See the file UPGRADE for more detailed upgrade instructions.
 163
 164 For notes on 1.22.x and older releases, see HISTORY.
 165
 166 == Online documentation ==
 167
 168 Documentation for both end-users and site administrators is available on
 169 MediaWiki.org, and is covered under the GNU Free Documentation License (except
 170 for pages that explicitly state that their contents are in the public domain):
 171
 172         https://www.mediawiki.org/wiki/Documentation
 173
 174 == Mailing list ==
 175
 176 A mailing list is available for MediaWiki user support and discussion:
 177
 178         https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 179
 180 A low-traffic announcements-only list is also available:
 181
 182         https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 183
 184 It's highly recommended that you sign up for one of these lists if you're
 185 going to run a public MediaWiki, so you can be notified of security fixes.
 186
 187 == IRC help ==
 188
 189 There's usually someone online in #mediawiki on irc.freenode.net.
