= 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 1.8 ==
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
== Configuration changes ==
* $wgUseETag, to enable/disable sending of HTTP ETag headers
(default: disabled)
== Major new features ==
* (bug 7098) Add an option to disable/enable sending of HTTP ETag headers,
as it seems to result in broken behaviour in combination with Squid 2.6
(disabled by default).
* (bug 550) Allow blocks on anonymous users only.
* (bug 6420) Render thumbnails for DJVU images, support multipage DJVU display
on image pages. Added new 'page=' thumbnail option to select a page from a
multipage djvu for thumbnail generation.
* Full Postgres support is now enabled. It requires version 8.1 or better, and
needs to have both plpgsql and tsearch2 already installed.
* (bug 6386) fix grammatical errors in danish naming of talk namespaces.
== Changes since 1.7 ==
* Introduced AjaxResponse object, superceding AjaxCachePolicy
* Changes to sajax_do_call: optionally accept an element to fill instead of a
callback function; take the target function or element as a third parameter;
pass the full XMLHttpRequest object to the handler function, instead of just
the resultText value; use HTTP response codes to report errors.
* (bug 6562) Removed unmaintained ParserXml.php for now
* History paging overlap bug fixed
* (bug 6586) Regression in "unblocked" subtitle
* Don't put empty-page message into view-source when page text is blank
* (bug 6587) Remove redundant "allnonarticles" message
* Block improvements: Allow blocks on anonymous users only. Optionally allow
or disallow account creation from blocked IP addresses. Prevent duplicate
blocks. Fixed the problem of expiry and unblocking erroneously affecting
multiple blocks. Fixed confusing lack of error message when a blocked user
attempts to create an account. Fixed inefficiency of Special:Ipblocklist in
the presence of large numbers of blocks; added indexes and implemented an
indexed pager.
* (bug 6448) Allow filtering of Special:Newpages according to username
* (bug 6618) Improve permissions/error detection in Special:Lockdb
* Quick hack for extension testing: parser test doesn't create new message
cache object.
* (bug 6299) Maintain parser's revision ID across recursive calls to fix
{{REVISIONID}} when Cite extension is used
* (bug 6622) Removed deprecated function Image::newFromTitle
* (bug 6627) Fix regression in Special:Ipblocklist with table prefix
* Removed forced dereferencements (new() returns a reference in PHP5)
* Note about $wgUploadSizeWarning using byte
* (bug 6592) Add most viewed pages summary to Special:Statistics
* Pre-strip characters ignored in IDNs from URLs so they can't be used
to break the blacklists for regular URLs
* Fix regression in blocking of user accounts
* (bug 6635) Fix regression searching for range blocks on Ipblocklist
* Fix regression searching Ipblocklist with ugly URLs
* (bug 6639) Use a consistent default for upload directories
* Preserve entered reason when reporting unconfirmed lock on Special:Lockdb
* (bug 6642) Don't offer to unlock the database when it isn't locked
* cleanupTitles.php changed from --dry-run option to --fix, so default
behavior is now a non-invasive check as with namespaceDupes.php
* (bug 6660) Fix behaviour of EditPage::blockedPage() when the article does
not exist; now doesn't show the source box if the user hasn't provided it
(blocked mid-edit) and the page doesn't exist
* Improve default value of "blockedtext"
* (bug 6680) Added localisation for Dutch bookstore list (nl)
* Renamed maintainace script redundanttrans.php to unusedMessages.php - clearer usage
* Fix regression which allowed some blocked users to create additional accounts
* (bug 6657) Fix Hungarian linktrail
* (bug 6751) Fix preview of blanked section with edit on first preview option
* (bug 5456) Separate MediaWiki:Search into messages for both noun and verb,
introduced 'MediaWiki:Searchbutton'
* Made lines from initialiseMessages() appear as list items during installation
* Moved the bulk of the localisation data from the Language*.php files to the
Messages*.php files. Deleted most of the Languages*.php files.
* Introduced "stub global" framework to provide deferred initialisation of core
modules.
* Removed placeholder values for $wgTitle and $wgArticle, these variables will
now be null during the initialisation process, until they are set by index.php
or another entry point.
* Added DBA cache type, for BDB-style caches.
* Removed custom date format functions, replacing them with a format string in
the style of PHP's date(). Used string identifiers instead of integer
identifiers, in both the language files and user preferences. Migration should
be transparent in most cases.
* Simplified the initialisation API for LoadBalancer objects.
* Removed the broken altencoding feature.
* Moved default user options and toggles from Language to User. Language objects
are still able to define default preference overrides and extra user toggles,
via a slightly different interface.
* Don't include the date option in the parser cache rendering hash unless
$wgUseDynamicDates is enabled.
* Merged LanguageUtf8 with Language. Removed LanguageUtf8.php.
* Removed inclusion of language files from the bottom of Language.php. This is
now consistently done from Language::factory().

profiler during maintenance scripts.
* Added "serialized" directory, for storing precompiled data in serialized form.

page title, etc.

framework and wgAjaxSearch to enable the suggest feature for the search box.

default message text

== Compatibility ==
MediaWiki 1.8 requires PHP 5 (5.1 recommended). PHP 4 is no longer supported.
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 ==
Several changes to the database have been made from 1.6:
* A new "langlinks" table tracks interlanguage links
* A new "filearchive" table stores information on deleted files
* A new "querycache_info" table stores information on query page updates
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.)
For notes on 1.5.x and older releases, see HISTORY.
=== Online documentation ===
Documentation for both end-users and site administrators is currently being
built up on Meta-Wikipedia, and is covered under the GNU Free Documentation
License:
http://www.mediawiki.org/wiki/Documentation
=== Mailing list ===
A MediaWiki-l mailing list has been set up distinct from the Wikipedia
wikitech-l list:
http://mail.wikimedia.org/mailman/listinfo/mediawiki-l
A low-traffic announcements-only list is also available:
http://mail.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
