   6 == MediaWiki 1.14 ==
   7
   8 THIS IS NOT A RELEASE YET
   9
  10 MediaWiki is now using a "continuous integration" development model with
  11 quarterly snapshot releases. The latest development code is always kept
  12 "ready to run", and in fact runs our own sites on Wikipedia.
  13
  14 Release branches will continue to receive security updates for about a year
  15 from first release, but nonessential bugfixes and feature developments
  16 will be made on the development trunk and appear in the next quarterly release.
  17
  18 Those wishing to use the latest code instead of a branch release can obtain
  19 it from source control: http://www.mediawiki.org/wiki/Download_from_SVN

  21 === Configuration changes in 1.14 ===
  22
  23 * $wgExemptFromUserRobotsControl is an array of namespaces to be exempt from
  24   the effect of the new __INDEX__/__NOINDEX__ magic words.  (Default: null, ex-
  25   empt all content namespaces.)
  26 * $wgForwardSearchUrl has been removed entirely. Documented setting since 1.4
  27   has been $wgSearchForwardUrl.
  28 * (bug 15080) $wgOverrideSiteFeed has been added. Setting either
  29   $wgSiteFeed['rss'] or 'atom' to a URL will override the default Recent Changes
  30   feed that appears on all pages.
  31 * $wgSQLiteDataDirMode has been introduced as the default directory mode for
  32   SQLite data directories on creation. Note this setting is separate from
  33   $wgDirectoryMode, which applies to all normal directories created by MediaWiki.
  34 * $wgGroupsAddToSelf and $wgGroupsRemoveFromSelf now work more like
  35   $wgAddGroups and $wgRemoveGroups, where the user must belong to a specified
  36   group in order to add or remove those groups from themselves.
  37   Backwards compatibility is maintained.
  38 * $wgRestrictDisplayTitle controls if the use of the {{DISPLAYTITLE}} magic
  39   word is restricted to titles equivalent to the actual page title. This
  40   is true per default, but can be set to false to allow any title.
  41 * $wgSpamRegex may now be an array of multiple regular expressions.
  42 * $wgAjaxSearch has been removed; use $wgEnableMWSuggest instead.
  43
  44 === New features in 1.14 ===
  45
  46 * New URL syntaxes for Special:ListUsers - 'Special:ListUsers/USER' and
  47   'Special:ListUsers/GROUP/USER', in addition to the older syntax
  48   'Special:ListUsers/GROUP' where GROUP is a valid group name.
  49 * Configurable per-namespace and per-page notices for the edit form,
  50   respectively MediaWiki:Editnotice-# where # is the namespace number, and
  51   MediaWiki:Editnotice-#-PAGENAME where # is the page's namespace number and
  52   PAGENAME is the page name minus the namespace prefix.
  53 * (bug 8068) New __INDEX__ and __NOINDEX__ magic words allow user control of
  54   search engine indexing on a per-article basis.
  55 * Handheld stylesheet options
  56 * Added 'DoEditSectionLink' hook as a cleaner unified version of the old
  57   'EditSectionLink' and 'EditSectionLinkForOther' hooks.  Note that the
  58   'EditSectionLinkForOther' hook has been removed, but 'EditSectionLink' is
  59   run in all cases instead, so extensions using the old hooks should still work
  60   if they ran roughly the same code for both hooks (as is almost certain).
  61 * Signature (~~~~) "cleaning", i.e. template removal, can be disabled with
  62   $wgCleanSignatures=false
  63 * Extensions can use the SkinBuildSidebar hook to modify the content of the
  64   sidebar and add custom portlets to it
  65 * Added 'MakeGlobalVariablesScript' hook for extensions to be able to add vari-
  66   ables into into the output of Skin::makeVariablesScript
  67 * (bug 13846) Added $wgAddGroups and $wgRemoveGroups display on
  68   Special:ListGroupRights
  69 * (bug 14377) Add a date selector to history pages
  70 * (bug 15007) New 'pagetitle-view-mainpage' message allows the HTML <title> of
  71   the main page to be customized
  72 * Added $wgDisableTitleConversion to disabling the conversion for all pages on
  73   the wiki
  74 * Added 'noconvertlink' toggle that can be set per user preferences, also
  75   added 'convertlink=no|yes' on GET requests whether have the link titles
  76   being converted or not
  77 * (bug 14921) Special:Contributions/: add user name to <title>
  78   Patch by Emufarmers
  79 * Unescape more "safe" characters when producing URLs, for added prettiness
  80 * Introduced a new hook 'SkinAfterContent' that allows extensions to add text
  81   after the page content and article metadata. Updated all skins and skin
  82   templates to work with that hook.
  83 * (bug 14929) removeUnusedAccounts.php now supports 'ignore-touched' and
  84   'ignore-groups'. Patch by Louperivois
  85 * (bug 15127) Work around minor display glitch in Opera.
  86 * By default, reject file uploads that look like ZIP files, to avoid the
  87   so-called GIFAR vulnerability.
  88 * (bug 15141) Give ability to only list protected pages with the cascading
  89   option enabled on Special:ProtectedPages
  90 * (bug 15157) Special:Watchlist has the same options as Special:Watchlist:
  91   Show/Hide logged in users, Show/Hide anonymous, Invert namespace selection
  92 * Added hook 'UserrightsChangeableGroups' to allow modification of what
  93   groups may be added or removed via the Special:UserRights interface.
  94 * HTML entities like &nbsp; now work (are not escaped) in edit summaries.
  95 * (bug 13815) In the comment for page moves, use the colon-separator message
  96   instead of a hardcoded colon.
  97 * Allow <gallery> to accept image names without an Image: prefix
  98 * Add tooltips to rollback and undo links
  99 * Backend upload code has been removed from SpecialUpload.php. This may cause
 100   backwards incompatibility with upload extensions.
 101 * BMP images are now displayed as PNG
 102 * (bug 13471) Added NUMBERINGROUP magic word
 103 * (bug 11884) Now support Flash EXIF attribute

 171 * API search now falls back to fulltext search by default when using Lucene

 191 * Added action=watch
 192 * (bug 15275) apprefix and related parameters ignore spaces at the end

 197
 198 === Languages updated in 1.14 ===
 199
 200 MediaWiki supports over 300 languages. Many localisations are updated
 201 regularly. Below only new and removed languages are listed.
 202
 203 (no changes yet)
 204
 205 == Compatibility ==
 206
 207 MediaWiki 1.14 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.
 208
 209 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
 210 http://bugs.php.net/bug.php?id=34879
 211 Upgrade affected systems to PHP 5.1 or higher.
 212
 213 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
 214 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
 215
 216
 217 == Upgrading ==
 218
 219 If upgrading from before 1.11, and you are using a wiki as a commons repository,
 220 make sure that it is updated as well. Otherwise, errors may arise due to
 221 database schema changes.
 222
 223 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 224 new database fields are filled with data.
 225
 226 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 227 changes are made, and there is a slightly higher chance that things could
 228 break. Don't forget to always back up your database before upgrading!
 229
 230 See the file UPGRADE for more detailed upgrade instructions.
 231
 232
 233 === Caveats ===
 234
 235 Some output, particularly involving user-supplied inline HTML, may not
 236 produce 100% valid or well-formed XHTML output. Testers are welcome to
 237 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 238 cases, but this is not recommended on live sites. (This must be set for
 239 MathML to display properly in Mozilla.)
 240
 241 For notes on 1.13.x and older releases, see HISTORY.
 242
 243
 244 === Online documentation ===
 245
 246 Documentation for both end-users and site administrators is currently being
 247 built up on MediaWiki.org, and is covered under the GNU Free Documentation
 248 License (except for pages that explicitly state that their contents are in
 249 the public domain) :
 250
 251   http://www.mediawiki.org/wiki/Documentation
 252
 253
 254 === Mailing list ===
 255
 256 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 257 wikitech-l list:
 258
 259   http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 260
 261 A low-traffic announcements-only list is also available:
 262
 263   http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 264
 265 It's highly recommended that you sign up for one of these lists if you're
 266 going to run a public MediaWiki, so you can be notified of security fixes.
 267
 268
 269 === IRC help ===
 270
 271 There's usually someone online in #mediawiki on irc.freenode.net
