   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 1.18 ===
  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 * OutputPage::isUserJsAllowed() no longer returns false when scripts are allowed by the page,
  39   but $wgAllowUserJs is set to false.
  40

  43   'disableaccount' privilege to permanently deactivate user accounts.
  44 * (bug 8130) Query pages should limit to content namespaces, not just main namespace
  45 * Search suggestions (other than in the Vector skin) will now use the HTML5

 144 === Languages updated in 1.18 ===
 145
 146 MediaWiki supports over 330 languages. Many localisations are updated
 147 regularly. Below only new and removed languages are listed, as well as
 148 changes to languages because of Bugzilla reports.
 149
 150 == Compatibility ==
 151
 152 MediaWiki 1.18 requires PHP 5.1 (5.2 recommended). PHP 4 is no longer
 153 supported.
 154
 155 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
 156 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
 157
 158
 159 == Upgrading ==
 160
 161 1.18 has several database changes since 1.17, and will not work without schema
 162 updates.
 163
 164 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
 165 ry, make sure that it is updated as well. Otherwise, errors may arise due to
 166 database schema changes.
 167
 168 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 169 new database fields are filled with data.
 170
 171 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 172 changes are made, and there is a slightly higher chance that things could
 173 break. Don't forget to always back up your database before upgrading!
 174
 175 See the file UPGRADE for more detailed upgrade instructions.
 176
 177
 178 === Caveats ===
 179
 180 Some output, particularly involving user-supplied inline HTML, may not
 181 produce 100% valid or well-formed XHTML output. Testers are welcome to
 182 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 183 cases, but this is not recommended on live sites. (This must be set for
 184 MathML to display properly in Mozilla.)
 185
 186 For notes on 1.17.x and older releases, see HISTORY.
 187
 188
 189 === Online documentation ===
 190
 191 Documentation for both end-users and site administrators is currently being
 192 built up on MediaWiki.org, and is covered under the GNU Free Documentation
 193 License (except for pages that explicitly state that their contents are in
 194 the public domain) :

 196         http://www.mediawiki.org/wiki/Documentation
 197
 198
 199 === Mailing list ===
 200
 201 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 202 wikitech-l list:
 203
 204         http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 205
 206 A low-traffic announcements-only list is also available:
 207
 208         http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 209
 210 It's highly recommended that you sign up for one of these lists if you're
 211 going to run a public MediaWiki, so you can be notified of security fixes.
 212
 213
 214 === IRC help ===
 215
 216 There's usually someone online in #mediawiki on irc.freenode.net
