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 1.18 ==
|
|
|
|
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 in 1.18 ===
|
|
* The WantedPages::getSQL hook has been removed and replaced with
|
|
WantedPages::getQueryInfo . This may break older extensions.
|
|
* $wgUseCombinedLoginLink controls whether to output a combined
|
|
login / create account link in the personal bar, or to output separate login
|
|
and create account links
|
|
* Skin names are no longer created based on a ucfirst version of the key in
|
|
$wgValidSkinNames but now the value. This means for
|
|
$wgValidSkinNames["monobook"] = "MonoBook"; the skin loader will no longer try
|
|
loading SkinMonobook and will instead load SkinMonoBook.
|
|
* The parser now attempts to output markers for editsection tokens and defer the
|
|
rendering of them so skin and language specific markup does not need to be
|
|
saved inside the parser cache note that this changes the cache key making all
|
|
old entries in the parser cache invalid you can set $wgUseEditSectionTokens to
|
|
false to disable this and keep your old parser cache entries.
|
|
Note that this feature should reduce parser cache fragmentation when enabled.
|
|
* $wgMaxUploadSize may now be set to an array to specify the upload size limit
|
|
per upload type.
|
|
* $wgAPICacheHelp added in 1.16 is now removed. To disable API help caching, set
|
|
$wgAPICacheHelpTimeout = 0;
|
|
* OutputPage::isUserJsAllowed() no longer returns false when scripts are allowed
|
|
by the page, but $wgAllowUserJs is set to false.
|
|
* Pure "Skin" class based custom skins are no longer supported, all custom skins
|
|
should be put together using SkinTemplate and BaseTemplate or QuickTemplate.
|
|
|
|

|

=== Languages updated in 1.18 ===
|
|
|
|
MediaWiki supports over 330 languages. Many localisations are updated
|
|
regularly. Below only new and removed languages are listed, as well as
|
|
changes to languages because of Bugzilla reports.
|
|
|
|
* (bug 17160) Gender specific display text for User namespace
|
|
|
|
== Compatibility ==
|
|
|
|
MediaWiki 1.18 requires PHP 5.1 (5.2 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 ==
|
|
|
|
1.18 has several database changes since 1.17, and will not work without schema
|
|
updates.
|
|
|
|
If upgrading from before 1.11, and you are using a wiki as a commons reposito-
|
|
ry, make sure that it is updated as well. Otherwise, errors may arise due to
|
|
database schema changes.
|
|
|
|
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.)
|
|
|
|

=== 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) :
|
|
|
|
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://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
