= 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 ==

THIS IS NOT A RELEASE YET.

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

== Configuration changes since 1.10 ==

* $wgThumbUpright - Adjust width of upright images when parameter 'upright' is
  used

== New features since 1.10 ==

* (bug 8868) Separate "blocked" message for autoblocks

  Special:Watchlist
* (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
* Introducing 'frameless' keyword to [[Image:]] syntax which respects the
  user preferences for image width like 'thumb' but without a frame.

  file repositories.

* (bug 10055) Populate email address and real name properties of User objects

* (bug 9328) Use "revision-info-current" message in place of "revision-info"
  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.
* (bug 9415) Added options to Special:Protect to allow setting of per-page robot
  policies. This can be done only by users with the 'editrobots' permission

== 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.)

=== Mailing list ===

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

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.
