= 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 1.9 ==

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 development happen
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

  run along with the main batch.
* Run PHP install version checks on update.php so command-line updaters see
  new version requirements

  right on Apache too!
* Replace 'old-revision-navigation' message with 'revision-info' and
  'revision-nav' messages, wrapped in divs with appropriate id's.
* (bug 4178) MediaWiki:Common.js will now be included for all users if

  and user JS subpages.

  any added or removed templates, and works as expected for section edits.

  on current page instead of loading the latest version.

  JavaScript.

   the autosummary code so it's all done in one function. doEdit is getting too
   big!
* (bug 7554) The correct MIME type for SVG images is now displayed on the
  image page (image/svg+xml, not image/svg).
* (bug 7883) Added autoblock whitelisting feature, using which specific ranges
   can be protected from autoblocking. These ranges are specified, in list format,
   in the autoblock_whitelist system message.
* Added placeholders for text injection by hooks to EditPage.php
* (bug 8009) Automatic edit summary for redirects is not filled for edits in existing pages
* Installer support for experimental MySQL 4.1/5.0 binary-safe schema
* Use INSERT IGNORE for db-based BagOStuff add/insert, for more memcache-like
  behavior when keys already exist on add (instead of dying with an error...)
* Add a hook 'UploadForm:initial' before the upload form is generated, and two
  member variable for text injection into the form, which can be filled by the hooks.
* (bug 6295) Add a "revision patching" functionality, where an edit can be undone
  (with a functionality similar to diff rev1 rev2 | patch -R rev3 -o rev3).
  This is triggered by including &undo=revid in an edit URL. A link to a URL
  that will undo a given edit is shown on NEW NON-CURRENT revision headers on diff pages.
* Fix display of link in "already rolled back" message for image/category pages

  broken proxies that mangle such characters in form submissions

* (bug 7946) importTextFile.php doesn't perform pre-save transform

== Compatibility ==

MediaWiki 1.9 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 ==

Some minor database changes have been made since 1.7:
* new fields and indexes on ipblocks
* index change on recentchanges

Several changes from 1.5 and 1.6 do require updates to be run on upgrade.
To ensure that these tables are filled with data, run refreshLinks.php after
the upgrade.

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.)
