MediaWiki release notes

Security reminder: MediaWiki does not require PHP's register_globals setting since version 1.2.0. If you have it on, turn it *off* if you can.

MediaWiki 1.11.0

September 10, 2007

This is the Fall 2007 snapshot release of MediaWiki.

MediaWiki is now using a "continuous integration" development model with quarterly snapshot releases. The latest development code is always kept "ready to run", and in fact runs our own sites on Wikipedia.

Release branches will continue to receive security updates for about a year from first release, but nonessential bugfixes and feature developments will be made on the development trunk and appear in the next quarterly release.

Those wishing to use the latest code instead of a branch release can obtain it from source control: http://www.mediawiki.org/wiki/Download_from_SVN

Changes since 1.11.0rc1

A possible HTML/XSS injection vector in the API pretty-printing mode has been found and fixed.

The vulnerability may be worked around in an unfixed version by simply disabling the API interface if it is not in use, by adding this to LocalSettings.php:

 $wgEnableAPI = false;

(This is the default setting in 1.8.x.)

Not vulnerable versions:

  • 1.11 >= 1.11.0
  • 1.10 >= 1.10.2
  • 1.9 >= 1.9.4
  • 1.8 >= 1.8.5

Vulnerable versions:

  • 1.11 <= 1.11.0rc1
  • 1.10 <= 1.10.1
  • 1.9 <= 1.9.3
  • 1.8 <= 1.8.4 (if $wgEnableAPI has been switched on)

MediaWiki 1.7 and below are not affected as they do not include the faulty function, however the BotQuery extension is similarly vulnerable unless updated to the latest SVN version.


Configuration changes since 1.10

  • $wgThumbUpright - Adjust width of upright images when parameter 'upright' is
 used
  • $wgAddGroups, $wgRemoveGroups - Finer control over who can assign which
 usergroups
  • $wgEnotifImpersonal, $wgEnotifUseJobQ - Bulk mail options for large sites
  • $wgShowHostnames - Expose server host names through the API and HTML comments
  • $wgSaveDeletedFiles has been removed, the feature is now enabled unconditionally

New features since 1.10

  • (bug 8818) Expose "wpDestFile" as parameter $1 to "uploaddisabledtext"
  • Introducing new image keyword 'upright' and corresponding variable
 $wgThumbUpright. This allows better proportional view of upright images
 related to landscape images on a page without nailing the width of upright
 images to a fix value which makes views for anon unproportional and user
 preferences useless
  • (bug 6072) Introducing 'border' keyword to the [[Image:]] syntax

 user preferences for image width like 'thumb' but without a frame.

 when viewing the current revision of a page, if available
  • (bug 8890) Enable wiki text for "license" message
  • Throw a showstopper exception when a hook function fails to return a value.
 Forgetting to give a 'true' return value is a very common error which tends
 to cause hard-to-track-down interactions between extensions.

== Compatibility ==

MediaWiki 1.11 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.

PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing: http://bugs.php.net/bug.php?id=34879 Upgrade affected systems to PHP 5.1 or higher.

MySQL 3.23.x is no longer supported; some older hosts may need to upgrade. At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.


== Upgrading ==

1.11 has several database changes since 1.10, and will not work without schema updates.

If upgrading from before 1.7, you may want to run refreshLinks.php to ensure new database fields are filled with data.

If you are upgrading from MediaWiki 1.4.x or earlier, some major database changes are made, and there is a slightly higher chance that things could break. Don't forget to always back up your database before upgrading!

See the file UPGRADE for more detailed upgrade instructions.

=== Caveats ===

Some output, particularly involving user-supplied inline HTML, may not produce 100% valid or well-formed XHTML output. Testers are welcome to set $wgMimeType = "application/xhtml+xml"; to test for remaining problem cases, but this is not recommended on live sites. (This must be set for MathML to display properly in Mozilla.)


For notes on 1.10.x and older releases, see HISTORY.


=== Online documentation ===

Documentation for both end-users and site administrators is currently being built up on MediaWiki.org, and is covered under the GNU Free Documentation License (except for pages that explicitly state that their contents are in the public domain) :

=== Mailing list ===

A MediaWiki-l mailing list has been set up distinct from the Wikipedia wikitech-l list:

 http://lists.wikimedia.org/mailman/listinfo/mediawiki-l

A low-traffic announcements-only list is also available:

 http://lists.wikimedia.org/mailman/listinfo/mediawiki-announce

It's highly recommended that you sign up for one of these lists if you're going to run a public MediaWiki, so you can be notified of security fixes.


=== IRC help ===

There's usually someone online in #mediawiki on irc.freenode.net
