   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 1.18 ===
  22 * The WantedPages::getSQL hook has been removed and replaced with
  23   WantedPages::getQueryInfo . This may break older extensions.
  24 * $wgUseCombinedLoginLink controls whether to output a combined login / create account
  25   link in the personal bar, or to output separate login and create account links
  26 * Skin names are no longer created based on a ucfirst version of the key in $wgValidSkinNames but now
  27   the value. This means for $wgValidSkinNames["monobook"] = "MonoBook"; the skin
  28   loader will no longer try loading SkinMonobook and will instead load SkinMonoBook.
  29 * The parser now attempts to output markers for editsection tokens and defer the rendering
  30   of them so skin and language specific markup does not need to be saved inside the parser cache
  31   note that this changes the cache key making all old entries in the parser cache invalid you
  32   can set $wgUseEditSectionTokens to false to disable this and keep your old parser cache entries.
  33   Note that this feature should reduce parser cache fragmentation when enabled.
  34 * $wgMaxUploadSize may now be set to an array to specify the upload size limit
  35   per upload type.
  36 * $wgAPICacheHelp added in 1.16 is now removed. To disable API help caching, set
  37   $wgAPICacheHelpTimeout = 0;
  38
  39 === New features in 1.18 ===
  40 * Added a special page, disabled by default, that allows users with the
  41   'disableaccount' privilege to permanently deactivate user accounts.
  42 * (bug 8130) Query pages should limit to content namespaces, not just main namespace
  43 * Search suggestions (other than in the Vector skin) will now use the HTML5
  44   datalist feature where supported, currently only Firefox 4.

 104 === Languages updated in 1.18 ===
 105
 106 MediaWiki supports over 330 languages. Many localisations are updated
 107 regularly. Below only new and removed languages are listed, as well as
 108 changes to languages because of Bugzilla reports.
 109
 110 == Compatibility ==
 111
 112 MediaWiki 1.18 requires PHP 5.1 (5.2 recommended). PHP 4 is no longer
 113 supported.
 114
 115 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
 116 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
 117
 118
 119 == Upgrading ==
 120
 121 1.18 has several database changes since 1.17, and will not work without schema
 122 updates.
 123
 124 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
 125 ry, make sure that it is updated as well. Otherwise, errors may arise due to
 126 database schema changes.
 127
 128 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 129 new database fields are filled with data.
 130
 131 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 132 changes are made, and there is a slightly higher chance that things could
 133 break. Don't forget to always back up your database before upgrading!
 134
 135 See the file UPGRADE for more detailed upgrade instructions.
 136
 137
 138 === Caveats ===
 139
 140 Some output, particularly involving user-supplied inline HTML, may not
 141 produce 100% valid or well-formed XHTML output. Testers are welcome to
 142 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 143 cases, but this is not recommended on live sites. (This must be set for
 144 MathML to display properly in Mozilla.)
 145
 146 For notes on 1.17.x and older releases, see HISTORY.
 147
 148
 149 === Online documentation ===
 150
 151 Documentation for both end-users and site administrators is currently being
 152 built up on MediaWiki.org, and is covered under the GNU Free Documentation
 153 License (except for pages that explicitly state that their contents are in
 154 the public domain) :

 156         http://www.mediawiki.org/wiki/Documentation
 157
 158
 159 === Mailing list ===
 160
 161 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 162 wikitech-l list:
 163
 164         http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 165
 166 A low-traffic announcements-only list is also available:
 167
 168         http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 169
 170 It's highly recommended that you sign up for one of these lists if you're
 171 going to run a public MediaWiki, so you can be notified of security fixes.
 172
 173
 174 === IRC help ===
 175
 176 There's usually someone online in #mediawiki on irc.freenode.net
