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 * $wgSearchEverythingOnlyLoggedIn was removed as the 'searcheverything'
  18   user option was removed. Use $wgNamespacesToBeSearchedDefault instead or
  19   if you used to have $wgDefaultUserOptions['searcheverything'] = 1.
  20
  21 === New features in 1.24 ===
  22 * Added a new hook, "WhatLinksHereProps", to allow extensions to annotate
  23   WhatLinksHere entries.
  24 * Added a new hook, "ContentGetParserOutput", to customize parser output for
  25   a given content object.
  26 * Deprecated the hook "ShowRawCssJs", use "ContentGetParserOutput" instead.
  27 * HTMLForm's HTMLTextField now supports the 'url' type.
  28 * HTMLForm fields may now be dynamically hidden based on the values of other
  29   fields in the form.
  30 * HTMLForm now supports multiple copies of an input field or set of input
  31   fields, e.g. the form may request "one or more usernames" without having to
  32   have the user enter delimited list of names into a text field.
  33 * Added a new hook, "SidebarBeforeOutput", to allow to edit the structure of
  34   the sidebar just before its display.
  35 * (bug 49156) Added the mediawiki.cookie ResourceLoader module, which wraps
  36   jQuery.cookie so that getting/setting a cookie is syntactically and functionally
  37   similar to using the WebRequest#getCookie/WebResponse#setcookie methods.
  38 * (bug 44740) jQuery upgraded from 1.8.3 to 1.11.1. A new configuration option,
  39   $wgIncludejQueryMigrate, also loads the jQuery Migrate hack to let extensions
  40   and gadgets use the long-deprecated functions that were removed in jQuery 1.9.
  41   This option is turned off by default, and will be removed in MediaWiki 1.25.
  42 * (bug 47076) jQuery UI upgraded from 1.8.24 to 1.9.2.
  43 * Changes to content typography (fonts, etc.). See
  44   https://www.mediawiki.org/wiki/Typography_refresh for further information.
  45 * WikitextContent will now render redirects with the expected "redirect"
  46   header, rather than as an ordered list. Code calling Article::viewRedirect
  47   can probably be changed to no longer special-case redirects.
  48 * Header font set to a serif font stack. See
  49   https://www.mediawiki.org/wiki/Typography_refresh for further information.
  50 * (bug 65567) Added a new hook, "BeforeHttpsRedirect", to allow cancellation of the HTTP
  51   to HTTPS redirect due to forceHTTPS cookie, userRequires, etc.  This is only for page views,
  52   since this hook doesn't affect UserLogin, OAuth, CentralAuth, etc.
  53   ATTENTION: This hook is likely to be removed soon due to overall design of the system.
  54 * (bug 17367) It is now possible to add pages to your watchlist from
  55   Special:UnwatchedPages without reloading the special page.
  56 * New methods setVolatile and isVolatile are added to PPFrame, so that
  57   extensions such as Cite.php can mark that their output is volatile and
  58   shouldn't be cached.
  59 * (bug 52817) Advanced search options are now saved on the search page itself, rather
  60   than in a dedicated pane in the preferences panel.
  61 * (bug 44591) The dropdown actions menu (little triangle next to page tabs) in
  62   the Vector skin has gained a label that should make it more discoverable.
  63 * MWCryptHKDF added for fast, cryptographically secure random number generation
  64   that won't deplete openssl's entropy pool.
  65
  66 === Bug fixes in 1.24 ===
  67 * (bug 49116) Footer copyright notice is now always displayed in user language
  68   rather than content language (same as copyright notice for editing interface).
  69 * (bug 62258) A bug was fixed in File::getUnscaledThumb when a height
  70   restriction was present in the parameters.  Images with both the "frame"
  71   option and a size specification set will now always ignore the provided
  72   size and display an unscaled image, as the documentation has always
  73   claimed it would.
  74 * (bug 39035) Improved Vector skin performance by removing collapsibleNav,
  75   which used to collapse some sidebar elements by default.
  76   This removes -list id suffixes like p-lang-list: instead of using things like
  77   #p-lang-list, you can do #p-lang .body ul.
  78 * (bug 890) Links in Special:RecentChanges and Special:Watchlist no longer
  79   follow redirects to their target pages.
  80 * Parser now dies early if called recursively, instead of producing subtle bugs.
  81 * (bug 14323) Redirect pages, when viewed with redirect=no, no longer hide the
  82   remaining page content.
  83 * (bug 52587) Maintenance script deleteBatch.php no longer follows redirects
  84   in the file namespace and delete the file on the target page. It will still
  85   however delete the redirect page.
  86
  87 === Web API changes in 1.24 ===
  88 * action=parse API now supports prop=modules, which provides the list of
  89   ResourceLoader modules that should be used to enhance the parsed content.
  90 * action=query&meta=siteinfo&siprop=interwikimap returns a new "protorel"
  91   field which is true iff protocol-relative urls can be used to access
  92   a particular interwiki map entry.
  93 * ApiQueryLogEvents now provides logpage, which is the page ID from the
  94   logging table, if ids are requested and the user has the permissions.
  95 * action=edit now requires that appendtext, prependtext, or section=new be used
  96   when using the 'redirect' parameter, to prevent clients accidentally
  97   overwriting the target page with the content of the redirect.
  98 * action=logevents will now return an error if both letitle and leprefix are
  99   specified.
 100 * action=logevents has a new parameter, lenamespace, to allow filtering by
 101   namespace.
 102 * action=expandtemplates has a new parameter, prop, and a new output format.
 103   The old format is still used if prop isn't provided, but this is deprecated.
 104 * meta=userinfo can now return the count of unread pages on the watchlist.
 105 * list=watchlist can now filter by unread status.
 106
 107 === Languages updated in 1.24 ===
 108
 109 MediaWiki supports over 350 languages. Many localisations are updated
 110 regularly. Below only new and removed languages are listed, as well as
 111 changes to languages because of Bugzilla reports.
 112
 113 === Other changes in 1.24 ===
 114 * The deprecated jquery.delayedBind ResourceLoader module was removed.
 115 * The deprecated function mw.util.toggleToc was removed.
 116 * The Special:Search hooks SpecialSearchGo and SpecialSearchResultsAppend
 117   were removed as they were unused.
 118 * (bug 65477) User::pingLimiter() now has an additional profile point varying
 119   by action being used.
 120 * mediawiki.util.$content no longer supports old versions of the Vector,
 121   Monobook, Modern and CologneBlue skins that don't yet implement the "mw-body"
 122   and/or "mw-body-primary" class name in their html.
 123 * Added pp_sortkey column to page_props table, so pages can be efficiently
 124   queried and sorted by property value (bug 58032).
 125   See $wgPagePropsHaveSortkey if you want to postpone the schema change.
 126 * BREAKING CHANGE: The Modern and Cologne Blue skins were moved out of MediaWiki
 127   core to their own respective repositories. See also
 128   https://www.mediawiki.org/wiki/Skin:Modern and
 129   https://www.mediawiki.org/wiki/Skin:CologneBlue.
 130 * BREAKING CHANGE: Skins built for MediaWiki 1.15 and earlier that do not use
 131   the "headelement" template key are no longer supported. Setting
 132   $useHeadElement = false; is no longer supported and will not cause old keys
 133   like "headlinks", "skinnameclass", etc. to be defined.
 134 * The deprecated 'SpecialVersionExtensionTypes' hook was removed.
 135 * (bug 63891) Add 'X-Robots-Tag: noindex' header in action=render pages.
 136 * SpecialPage no longer supports the syntax for invoking wfSpecial*() functions.
 137   All special pages should subclass SpecialPage and implement the execute() method.
 138 * (bug 63755) The deprecated constants RC_MOVE and RC_MOVE_OVER_REDIRECT were
 139   removed.

 182 == Compatibility ==
 183
 184 MediaWiki 1.24 requires PHP 5.3.2 or later.
 185
 186 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 187 support for them is somewhat less mature. There is experimental support for
 188 Oracle and Microsoft SQL Server.
 189
 190 The supported versions are:
 191
 192 * MySQL 5.0.2 or later
 193 * PostgreSQL 8.3 or later
 194 * SQLite 3.3.7 or later
 195 * Oracle 9.0.1 or later
 196 * Microsoft SQL Server 2005 (9.00.1399)
 197
 198 == Upgrading ==
 199
 200 1.24 has several database changes since 1.23, and will not work without schema
 201 updates. Note that due to changes to some very large tables like the revision
 202 table, the schema update may take quite long (minutes on a medium sized site,
 203 many hours on a large site).
 204
 205 If upgrading from before 1.11, and you are using a wiki as a commons
 206 repository, make sure that it is updated as well. Otherwise, errors may arise
 207 due to database schema changes.
 208
 209 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 210 new database fields are filled with data.
 211
 212 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 213 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 214 with MediaWiki 1.21.
 215
 216 Don't forget to always back up your database before upgrading!
 217
 218 See the file UPGRADE for more detailed upgrade instructions.
 219
 220 For notes on 1.22.x and older releases, see HISTORY.
 221
 222 == Online documentation ==
 223
 224 Documentation for both end-users and site administrators is available on
 225 MediaWiki.org, and is covered under the GNU Free Documentation License (except
 226 for pages that explicitly state that their contents are in the public domain):
 227
 228         https://www.mediawiki.org/wiki/Documentation
 229
 230 == Mailing list ==
 231
 232 A mailing list is available for MediaWiki user support and discussion:
 233
 234         https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 235
 236 A low-traffic announcements-only list is also available:
 237
 238         https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 239
 240 It's highly recommended that you sign up for one of these lists if you're
 241 going to run a public MediaWiki, so you can be notified of security fixes.
 242
 243 == IRC help ==
 244
 245 There's usually someone online in #mediawiki on irc.freenode.net.
