   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 1.17 ===
  22 * DatabaseFunctions.php that was needed for compatibility with pre-1.3
  23   extensions has been removed.
  24 * $wgLogAutocreatedAccounts controls whether autocreation of accounts is logged
  25   to new users log.
  26 * $wgAllowImageTag can be set to true to whitelist the <img> tag in wikitext.
  27
  28 === New features in 1.17 ===
  29 * (bug 10183) Users can now add personal styles and scripts to all skins via
  30   User:<name>/common.css and /common.js (if user css/js is enabled)
  31 * (bug 22748) Add anchors on Special:ListGroupRights
  32 * (bug 21981) Add parameter 'showfilename' to <gallery> to automatically apply
  33   the names of the individual files within the gallery
  34 * (bug 12797) Add $wgGalleryOptions for adjusting of default gallery display
  35   options
  36 * $wgAllowUserCssPrefs option allows disabling CSS-based preferences; which can
  37   improve page loading speed.
  38 * Future-proof redirection to fragments in Gecko, so things work a little nicer
  39   if they fix <https://bugzilla.mozilla.org/show_bug.cgi?id=516293>.
  40 * Support git:// and mms:// protocols by default for external links
  41 * (bug 15810) Blocked admins can no longer unblock themselves without the
  42   'unblockself' permission (which they have by default)
  43 * (bug 18499) Added "enhanced" URL parameter to switch between old and enhanced
  44   changes list
  45 * (bug 22925) "sp-contributions-blocked-notice-anon" message now displayed when
  46   viewing contributions of a blocked IP address
  47 * (bug 22474) {{urlencode:}} now takes an optional second paramter for type of
  48   escaping.
  49 * Special:Listfiles now supports a username parameter
  50 * Special:Random carries over query string parameters
  51 * (bug 23206) Add Special::Search hook for detecting successful "Go"
  52 * When visiting a "red link" of a deleted file, a deletion and move log excerpt
  53   is provided on the Upload form.
  54 * (bug 22647) Add category details in search results.
  55 * (bug 23276) Add hook to Special:NewPages to modify query

  58 * (bug 20186) Allow filtering Special:Contributions for RevisionDeleted edits
  59 * (bug 22858) $wgLocalStylePath is by default set to the same value as
  60   $wgStylePath but should never point to a different domain than the site is
  61   on, allowing skins to use .htc files which are not cross-domain friendly.
  62 * ajaxwatch now uses the API and JQuery, and can be used to animate arbitrary
  63   watch links, not just to watch the page the link is on.
  64 * (bug 20193) Added $wgVectorShowVariantName global configuration variable
  65   which causes Vector to render the variants drop-down menu with a label
  66   showing the current variant name. This is off by default, pending further
  67   research into its user experience implications.

 168
 169 == Compatibility ==
 170
 171 MediaWiki 1.17 requires PHP 5.1 (5.2 recommended). PHP 4 is no longer
 172 supported.
 173
 174 MySQL 3.23.x is no longer supported; some older hosts may need to upgrade.
 175 At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.
 176
 177
 178 == Upgrading ==
 179
 180 1.17 has several database changes since 1.16, and will not work without schema
 181 updates.
 182
 183 If upgrading from before 1.11, and you are using a wiki as a commons reposito-
 184 ry, make sure that it is updated as well. Otherwise, errors may arise due to
 185 database schema changes.
 186
 187 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 188 new database fields are filled with data.
 189
 190 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 191 changes are made, and there is a slightly higher chance that things could
 192 break. Don't forget to always back up your database before upgrading!
 193
 194 See the file UPGRADE for more detailed upgrade instructions.
 195
 196
 197 === Caveats ===
 198
 199 Some output, particularly involving user-supplied inline HTML, may not
 200 produce 100% valid or well-formed XHTML output. Testers are welcome to
 201 set $wgMimeType = "application/xhtml+xml"; to test for remaining problem
 202 cases, but this is not recommended on live sites. (This must be set for
 203 MathML to display properly in Mozilla.)
 204
 205 For notes on 1.16.x and older releases, see HISTORY.

 207
 208 === Online documentation ===
 209
 210 Documentation for both end-users and site administrators is currently being
 211 built up on MediaWiki.org, and is covered under the GNU Free Documentation
 212 License (except for pages that explicitly state that their contents are in
 213 the public domain) :

 215   http://www.mediawiki.org/wiki/Documentation
 216
 217
 218 === Mailing list ===
 219
 220 A MediaWiki-l mailing list has been set up distinct from the Wikipedia
 221 wikitech-l list:
 222
 223   http://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 224
 225 A low-traffic announcements-only list is also available:
 226
 227   http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 228
 229 It's highly recommended that you sign up for one of these lists if you're
 230 going to run a public MediaWiki, so you can be notified of security fixes.
