   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

  41   'disableaccount' privilege to permanently deactivate user accounts.

 139 === Languages updated in 1.18 ===
 140
 141 MediaWiki supports over 330 languages. Many localisations are updated
 142 regularly. Below only new and removed languages are listed, as well as
 143 changes to languages because of Bugzilla reports.
 144
 145 == Compatibility ==
 146
 147 MediaWiki 1.18 requires PHP 5.1 (5.2 recommended). PHP 4 is no longer
 148 supported.
 149
 150 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
 151 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
 152
 153
 154 == Upgrading ==
 155
 156 1.18 has several database changes since 1.17, and will not work without schema
 157 updates.
 158
 159 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
 160 ry, make sure that it is updated as well. Otherwise, errors may arise due to
 161 database schema changes.
 162
 163 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 164 new database fields are filled with data.
 165
 166 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 167 changes are made, and there is a slightly higher chance that things could
 168 break. Don't forget to always back up your database before upgrading!
 169
 170 See the file UPGRADE for more detailed upgrade instructions.
 171
 172
 173 === Caveats ===
 174
 175 Some output, particularly involving user-supplied inline HTML, may not
 176 produce 100% valid or well-formed XHTML output. Testers are welcome to
 177 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 178 cases, but this is not recommended on live sites. (This must be set for
 179 MathML to display properly in Mozilla.)
 180
 181 For notes on 1.17.x and older releases, see HISTORY.
 182
 183
 184 === Online documentation ===
 185
 186 Documentation for both end-users and site administrators is currently being
 187 built up on MediaWiki.org, and is covered under the GNU Free Documentation
 188 License (except for pages that explicitly state that their contents are in
 189 the public domain) :

 192
 193
 194 === Mailing list ===
 195
 196 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 197 wikitech-l list:
 198
 199         http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 200
 201 A low-traffic announcements-only list is also available:
 202
 203         http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 204
 205 It's highly recommended that you sign up for one of these lists if you're
 206 going to run a public MediaWiki, so you can be notified of security fixes.

 209 === IRC help ===
