   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
  37 === New features in 1.18 ===
  38 * Added a special page, disabled by default, that allows users with the
  39   'disableaccount' privilege to permanently deactivate user accounts.
  40 * (bug 8130) Query pages should limit to content namespaces, not just main namespace
  41 * Search suggestions (other than in the Vector skin) will now use the HTML5
  42   datalist feature where supported, currently only Firefox 4.
  43 * Special:Contribs now redirects to Special:Contributions

  89 === Languages updated in 1.18 ===
  90
  91 MediaWiki supports over 330 languages. Many localisations are updated
  92 regularly. Below only new and removed languages are listed, as well as
  93 changes to languages because of Bugzilla reports.
  94
  95 == Compatibility ==
  96
  97 MediaWiki 1.18 requires PHP 5.1 (5.2 recommended). PHP 4 is no longer
  98 supported.
  99
 100 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
 101 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
 102
 103
 104 == Upgrading ==
 105
 106 1.18 has several database changes since 1.17, and will not work without schema
 107 updates.
 108
 109 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
 110 ry, make sure that it is updated as well. Otherwise, errors may arise due to
 111 database schema changes.
 112
 113 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 114 new database fields are filled with data.
 115
 116 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 117 changes are made, and there is a slightly higher chance that things could
 118 break. Don't forget to always back up your database before upgrading!
 119
 120 See the file UPGRADE for more detailed upgrade instructions.
 121
 122
 123 === Caveats ===
 124
 125 Some output, particularly involving user-supplied inline HTML, may not
 126 produce 100% valid or well-formed XHTML output. Testers are welcome to
 127 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 128 cases, but this is not recommended on live sites. (This must be set for
 129 MathML to display properly in Mozilla.)
 130
 131 For notes on 1.17.x and older releases, see HISTORY.

 133
 134 === Online documentation ===
 135
 136 Documentation for both end-users and site administrators is currently being
 137 built up on MediaWiki.org, and is covered under the GNU Free Documentation
 138 License (except for pages that explicitly state that their contents are in
 139 the public domain) :

 143
 144 === Mailing list ===
 145
 146 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 147 wikitech-l list:
 148
 149         http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 150
 151 A low-traffic announcements-only list is also available:
 152
 153         http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 154
 155 It's highly recommended that you sign up for one of these lists if you're
 156 going to run a public MediaWiki, so you can be notified of security fixes.
