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

 158 == Compatibility ==
 159
 160 MediaWiki 1.24 requires PHP 5.3.2 or later.
 161
 162 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 163 support for them is somewhat less mature. There is experimental support for
 164 Oracle and Microsoft SQL Server.
 165
 166 The supported versions are:
 167
 168 * MySQL 5.0.2 or later
 169 * PostgreSQL 8.3 or later
 170 * SQLite 3.3.7 or later
 171 * Oracle 9.0.1 or later
 172 * Microsoft SQL Server 2005 (9.00.1399)
 173
 174 == Upgrading ==
 175
 176 1.24 has several database changes since 1.23, and will not work without schema
 177 updates. Note that due to changes to some very large tables like the revision
 178 table, the schema update may take quite long (minutes on a medium sized site,
 179 many hours on a large site).
 180
 181 If upgrading from before 1.11, and you are using a wiki as a commons
 182 repository, make sure that it is updated as well. Otherwise, errors may arise
 183 due to database schema changes.
 184
 185 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 186 new database fields are filled with data.
 187
 188 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 189 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 190 with MediaWiki 1.21.
 191
 192 Don't forget to always back up your database before upgrading!
 193
 194 See the file UPGRADE for more detailed upgrade instructions.
 195
 196 For notes on 1.22.x and older releases, see HISTORY.
 197
 198 == Online documentation ==
 199
 200 Documentation for both end-users and site administrators is available on
 201 MediaWiki.org, and is covered under the GNU Free Documentation License (except
 202 for pages that explicitly state that their contents are in the public domain):
 203
 204         https://www.mediawiki.org/wiki/Documentation
 205
 206 == Mailing list ==
 207
 208 A mailing list is available for MediaWiki user support and discussion:
 209
 210         https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 211
 212 A low-traffic announcements-only list is also available:
 213
 214         https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 215
 216 It's highly recommended that you sign up for one of these lists if you're
 217 going to run a public MediaWiki, so you can be notified of security fixes.
 218
 219 == IRC help ==
 220
 221 There's usually someone online in #mediawiki on irc.freenode.net.
