1 = MediaWiki release notes =
3 Security reminder: MediaWiki does not require PHP's register_globals
4 setting since version 1.2.0. If you have it on, turn it *off* if you can.
8 THIS IS NOT A RELEASE YET
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.
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.
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

28 === New features in 1.17 ===

36 * $wgAllowUserCssPrefs option allows disabling CSS-based preferences; which can
37 improve page loading speed.

39 if they fix <https://bugzilla.mozilla.org/show_bug.cgi?id=516293>.

41 * (bug 15810) Blocked admins can no longer unblock themselves without the

61 * ajaxwatch now uses the API and JQuery, and can be used to animate arbitrary
62 watch links, not just to watch the page the link is on.
63 * (bug 20193) Added $wgVectorShowVariantName global configuration varaible
64 which causes Vector to render the the variants drop-down menu with a label

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