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 * (bug 65567) Added a new hook, "BeforeHttpsRedirect", to allow cancellation of the HTTP
  45   to HTTPS redirect due to forceHTTPS cookie, userRequires, etc.  This is only for page views,
  46   since this hook doesn't affect UserLogin, OAuth, CentralAuth, etc.
  47   ATTENTION: This hook is likely to be removed soon due to overall design of the system.
  48
  49 === Bug fixes in 1.24 ===
  50 * (bug 49116) Footer copyright notice is now always displayed in user language
  51   rather than content language (same as copyright notice for editing interface).
  52 * (bug 62258) A bug was fixed in File::getUnscaledThumb when a height
  53   restriction was present in the parameters.  Images with both the "frame"
  54   option and a size specification set will now always ignore the provided
  55   size and display an unscaled image, as the documentation has always
  56   claimed it would.
  57 * (bug 39035) Improved Vector skin performance by removing collapsibleNav,
  58   which used to collapse some sidebar elements by default.
  59   This removes -list id suffixes like p-lang-list: instead of using things like
  60   #p-lang-list, you can do #p-lang .body ul.
  61 * (bug 890) Links in Special:RecentChanges and Special:Watchlist no longer
  62   follow redirects to their target pages.
  63 * Parser now dies early if called recursively, instead of producing subtle bugs.
  64 * (bug 14323) Redirect pages, when viewed with redirect=no, no longer hide the
  65   remaining page content.
  66 * (bug 52587) Maintenance script deleteBatch.php no longer follows redirects
  67   in the file namespace and delete the file on the target page. It will still
  68   however delete the redirect page.
  69
  70 === Web API changes in 1.24 ===
  71 * action=parse API now supports prop=modules, which provides the list of
  72   ResourceLoader modules that should be used to enhance the parsed content.
  73 * action=query&meta=siteinfo&siprop=interwikimap returns a new "protorel"
  74   field which is true iff protocol-relative urls can be used to access
  75   a particular interwiki map entry.
  76 * ApiQueryLogEvents now provides logpage, which is the page ID from the
  77   logging table, if ids are requested and the user has the permissions.
  78 * action=edit now requires that appendtext, prependtext, or section=new be used
  79   when using the 'redirect' parameter, to prevent clients accidentally
  80   overwriting the target page with the content of the redirect.
  81 * action=logevents will now return an error if both letitle and leprefix are
  82   specified.
  83 * action=logevents has a new parameter, lenamespace, to allow filtering by
  84   namespace.
  85
  86 === Languages updated in 1.24 ===
  87
  88 MediaWiki supports over 350 languages. Many localisations are updated
  89 regularly. Below only new and removed languages are listed, as well as
  90 changes to languages because of Bugzilla reports.
  91
  92 === Other changes in 1.24 ===
  93 * The deprecated jquery.delayedBind ResourceLoader module was removed.
  94 * The deprecated function mw.util.toggleToc was removed.
  95 * The Special:Search hooks SpecialSearchGo and SpecialSearchResultsAppend
  96   were removed as they were unused.
  97 * (bug 65477) User::pingLimiter() now has an additional profile point varying
  98   by action being used.
  99 * mediawiki.util.$content no longer supports old versions of the Vector,
 100   Monobook, Modern and CologneBlue skins that don't yet implement the "mw-body"
 101   and/or "mw-body-primary" class name in their html.
 102 * Added pp_sortkey column to page_props table, so pages can be efficiently
 103   queried and sorted by property value (bug 58032).
 104   See $wgPagePropsHaveSortkey if you want to postpone the schema change.
 105 * BREAKING CHANGE: The Modern and Cologne Blue skins were moved out of MediaWiki
 106   core to their own respective repositories. See also
 107   https://www.mediawiki.org/wiki/Skin:Modern and
 108   https://www.mediawiki.org/wiki/Skin:CologneBlue.

 151 == Compatibility ==
 152
 153 MediaWiki 1.24 requires PHP 5.3.2 or later.
 154
 155 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 156 support for them is somewhat less mature. There is experimental support for
 157 Oracle and Microsoft SQL Server.
 158
 159 The supported versions are:
 160
 161 * MySQL 5.0.2 or later
 162 * PostgreSQL 8.3 or later
 163 * SQLite 3.3.7 or later
 164 * Oracle 9.0.1 or later
 165 * Microsoft SQL Server 2005 (9.00.1399)
 166
 167 == Upgrading ==
 168
 169 1.24 has several database changes since 1.23, and will not work without schema
 170 updates. Note that due to changes to some very large tables like the revision
 171 table, the schema update may take quite long (minutes on a medium sized site,
 172 many hours on a large site).
 173
 174 If upgrading from before 1.11, and you are using a wiki as a commons
 175 repository, make sure that it is updated as well. Otherwise, errors may arise
 176 due to database schema changes.
 177
 178 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 179 new database fields are filled with data.
 180
 181 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 182 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 183 with MediaWiki 1.21.
 184
 185 Don't forget to always back up your database before upgrading!
 186
 187 See the file UPGRADE for more detailed upgrade instructions.
 188
 189 For notes on 1.22.x and older releases, see HISTORY.
 190
 191 == Online documentation ==
 192
 193 Documentation for both end-users and site administrators is available on
 194 MediaWiki.org, and is covered under the GNU Free Documentation License (except
 195 for pages that explicitly state that their contents are in the public domain):
 196
 197         https://www.mediawiki.org/wiki/Documentation
 198
 199 == Mailing list ==
 200
 201 A mailing list is available for MediaWiki user support and discussion:
 202
 203         https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 204
 205 A low-traffic announcements-only list is also available:
 206
 207         https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 208
 209 It's highly recommended that you sign up for one of these lists if you're
 210 going to run a public MediaWiki, so you can be notified of security fixes.
 211
 212 == IRC help ==
 213
 214 There's usually someone online in #mediawiki on irc.freenode.net.
