   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 * Editing the MediaWiki namespace is now unconditionally restricted to people
  44   with the editinterface right, configuring this in $wgNamespaceProtection
  45   is not required.
  46 * $wgAllowExternalImagesFrom may now be an array of multiple strings.
  47 * Introduced $wgEnableImageWhitelist to toggle the on-wiki external image
  48   whitelist on or off.
  49
  50 === New features in 1.14 ===
  51
  52 * New URL syntaxes for Special:ListUsers - 'Special:ListUsers/USER' and
  53   'Special:ListUsers/GROUP/USER', in addition to the older syntax
  54   'Special:ListUsers/GROUP' where GROUP is a valid group name.
  55 * Configurable per-namespace and per-page notices for the edit form,
  56   respectively MediaWiki:Editnotice-# where # is the namespace number, and
  57   MediaWiki:Editnotice-#-PAGENAME where # is the page's namespace number and
  58   PAGENAME is the page name minus the namespace prefix.
  59 * (bug 8068) New __INDEX__ and __NOINDEX__ magic words allow user control of
  60   search engine indexing on a per-article basis.
  61 * Handheld stylesheet options
  62 * Added 'DoEditSectionLink' hook as a cleaner unified version of the old
  63   'EditSectionLink' and 'EditSectionLinkForOther' hooks.  Note that the
  64   'EditSectionLinkForOther' hook has been removed, but 'EditSectionLink' is
  65   run in all cases instead, so extensions using the old hooks should still work
  66   if they ran roughly the same code for both hooks (as is almost certain).
  67 * Signature (~~~~) "cleaning", i.e. template removal, can be disabled with
  68   $wgCleanSignatures=false
  69 * Extensions can use the SkinBuildSidebar hook to modify the content of the
  70   sidebar and add custom portlets to it
  71 * Added 'MakeGlobalVariablesScript' hook for extensions to be able to add vari-
  72   ables into into the output of Skin::makeVariablesScript
  73 * (bug 13846) Added $wgAddGroups and $wgRemoveGroups display on
  74   Special:ListGroupRights
  75 * (bug 14377) Add a date selector to history pages
  76 * (bug 15007) New 'pagetitle-view-mainpage' message allows the HTML <title> of
  77   the main page to be customized
  78 * Added $wgDisableTitleConversion to disabling the conversion for all pages on
  79   the wiki
  80 * Added 'noconvertlink' toggle that can be set per user preferences, also
  81   added 'convertlink=no|yes' on GET requests whether have the link titles
  82   being converted or not
  83 * (bug 14921) Special:Contributions/: add user name to <title>
  84   Patch by Emufarmers
  85 * Unescape more "safe" characters when producing URLs, for added prettiness
  86 * Introduced a new hook 'SkinAfterContent' that allows extensions to add text
  87   after the page content and article metadata. Updated all skins and skin
  88   templates to work with that hook.
  89 * (bug 14929) removeUnusedAccounts.php now supports 'ignore-touched' and
  90   'ignore-groups'. Patch by Louperivois
  91 * (bug 15127) Work around minor display glitch in Opera.
  92 * By default, reject file uploads that look like ZIP files, to avoid the
  93   so-called GIFAR vulnerability.
  94 * (bug 15141) Give ability to only list protected pages with the cascading
  95   option enabled on Special:ProtectedPages
  96 * (bug 15157) Special:Watchlist has the same options as Special:Watchlist:
  97   Show/Hide logged in users, Show/Hide anonymous, Invert namespace selection
  98 * Added hook 'UserrightsChangeableGroups' to allow modification of what
  99   groups may be added or removed via the Special:UserRights interface.
 100 * HTML entities like &nbsp; now work (are not escaped) in edit summaries.
 101 * (bug 13815) In the comment for page moves, use the colon-separator message
 102   instead of a hardcoded colon.
 103 * Allow <gallery> to accept image names without an Image: prefix
 104 * Add tooltips to rollback and undo links
 105 * Backend upload code has been removed from SpecialUpload.php. This may cause
 106   backwards incompatibility with upload extensions.
 107 * BMP images are now displayed as PNG
 108 * (bug 13471) Added NUMBERINGROUP magic word
 109 * (bug 11884) Now support Flash EXIF attribute
 110 * Show thumbnails in the file history list, patch by User:Agbad
 111 * Added support of piped wikilinks using double-width brackets
 112 * Added an on-wiki external image whitelist. Items in this whitelist are
 113   treated as regular expression fragments to match for when possibly
 114   displaying an external image inline.

 181
 182 * Registration time of users registered before the DB field was created is now
 183   shown as empty instead of the current time.
 184 * API search now falls back to fulltext search by default when using Lucene
 185   or other engine which doesn't support a separate title search function.

 202   etc. (AKA lists) instead of arrays with pageIDs as keys (AKA hash tables)
 203   for consistency with other list modules.
 204 * Added action=watch
 205 * (bug 15275) apprefix and related parameters ignore spaces at the end
 206 * action=edit no longer throws unknown error 228  when trying to create an empty

 210 * (bug 15392) ApiFormatBase::formatHTML now uses $wgUrlProtocols.
 211
 212
 213 === Languages updated in 1.14 ===
 214
 215 MediaWiki supports over 300 languages. Many localisations are updated
 216 regularly. Below only new and removed languages are listed.
 217
 218 * Fiji Hindi (Devanagari script) (hif-deva)
 219 * Krio (kri)
 220 * Lezghian (lez)
 221 * Laz (lzz)
 222 * Niuean (niu)
 223 * Oromo (om)
 224 * Plautdietsch (pdt)

 227
 228 == Compatibility ==
 229
 230 MediaWiki 1.14 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.
 231
 232 PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:
 233 http://bugs.php.net/bug.php?id=34879
 234 Upgrade affected systems to PHP 5.1 or higher.
 235
 236 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
 237 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
 238
 239
 240 == Upgrading ==
 241
 242 If upgrading from before 1.11, and you are using a wiki as a commons repository,
 243 make sure that it is updated as well. Otherwise, errors may arise due to
 244 database schema changes.
 245
 246 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 247 new database fields are filled with data.
 248
 249 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 250 changes are made, and there is a slightly higher chance that things could
 251 break. Don't forget to always back up your database before upgrading!
 252
 253 See the file UPGRADE for more detailed upgrade instructions.
 254
 255
 256 === Caveats ===
 257
 258 Some output, particularly involving user-supplied inline HTML, may not
 259 produce 100% valid or well-formed XHTML output. Testers are welcome to
 260 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 261 cases, but this is not recommended on live sites. (This must be set for
 262 MathML to display properly in Mozilla.)
 263
 264 For notes on 1.13.x and older releases, see HISTORY.
 265
 266
 267 === Online documentation ===
 268
 269 Documentation for both end-users and site administrators is currently being
 270 built up on MediaWiki.org, and is covered under the GNU Free Documentation
 271 License (except for pages that explicitly state that their contents are in
 272 the public domain) :
 273
 274   http://www.mediawiki.org/wiki/Documentation
 275
 276
 277 === Mailing list ===
 278
 279 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 280 wikitech-l list:
 281
 282   http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 283
 284 A low-traffic announcements-only list is also available:
 285
 286   http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 287
 288 It's highly recommended that you sign up for one of these lists if you're
 289 going to run a public MediaWiki, so you can be notified of security fixes.

 291
 292 === IRC help ===
 293
 294 There's usually someone online in #mediawiki on irc.freenode.net
