MediaWiki Release Candidate 1.18.0rc 1
I'm happy to announce the availability of the first release candidate of
the new MediaWiki 1.18 release series.

Please try it out and let us know what you think. Don't run it on
any wikis that you really care about, unless you are both very
brave and very confident in your MediaWiki administration skills.

MediaWiki 1.18 is a large release that contains many new
features and bug fixes. This is a summary of the major changes of
interest to users. You can consult the RELEASE-NOTES file for the
full list of changes in this version.

Major features
- --------------

Better gender support
-- ---------------------

Until version 1.17, MediaWiki used neutral nouns to address and identify
users on their user page.
In English, this was not an issue since "User" matches both genders, but in
some languages the
neutral gender is always masculine; for example, this would cause
French-speaking female
Wikipedia users to be referred to as "Utilisateur" (male user) instead of
"Utilisatrice" (female user).
With version 1.18, user pages reflect the user's gender, if they have
specified it in their preferences.
More gender support (for instance in logs and user lists) will be available
in MediaWiki 1.19.

Improved file metadata support
-- -----------------------------

MediaWiki now detects the camera orientation from Exif metadata, and
rotates the picture
preview accordingly. The original file remains unchanged.

The overall metadata support in MediaWiki has been greatly extended.
Previously, MediaWiki could only
extract limited Exif metadata, and showed a subset of it on file
description pages. Since 1.18, MediaWiki
can extract IPTC and XMP metadata from uploaded files, and more Exif
information. This includes an
embedded description, author information, GPS coordinates, or copyright

Improved directionality support
-- -------------------------------

A lot of work has been done to fix directionality bugs (Left-To-Right,
Right-To-Left). Most notably bug 6100 is
fixed, which allows to display an RTL interface on an LTR wiki properly (and
vice versa). This was developed
under $wgBetterDirectionality, which is now no longer used because the
improvements are merged
with the core code.

A positive consequence is that the page content on wikis with multiple
scripts is aligned according to the
direction of the selected variant. For example, on a Kazakh language wiki,
selecting the Arabic script
variant will align the text as RTL, while selecting the Latin or Cyrillic
variant will align it as LTR.

Easily find where to customize interface messages
-- ---------------------------------------------

MediaWiki allows you to customize the user interface by editing pages in the
MediaWiki namespace.
However, even though they can be viewed at Special:AllMessages] the sheer
number of these messages
makes it difficult to find which one needs to be customized. In MediaWiki
1.18, a new pseudo-language
is introduced (qqx) to help people find such messages, by displaying the
messages' key instead of the
actual messages. All one has to do is append ?uselang=qqx to the page's
URL (see as an

New plugin for collapsible elements
-- -----------------------------------

The new jQuery.makeCollapsible allows you to create collapsible tables,
lists and so on,
by adding the class mw-collapsible to the elements.
See the manual for details:

Protocol-relative URLs
-- ----------------------

MediaWiki now supports protocol- relative URLs in links, interwiki targets
and $wgServer.
Protocol-relative URLs look like // ; the browser will
recognize this
as when following a link from an HTTP page, and when following a link from an HTTPS page.
This way, protocol-relative URLs enable a wiki to support HTTP and HTTPS
while serving
the same HTML for both, which means the parser cache doesn't have to be

More personalisable styles and scripts
-- --------------------------------------

MediaWiki now automatically loads javascript and stylesheets more specific
to each user.
There is a separate CSS and JS file for each usergroup
MediaWiki:Group-autoconfirmed.js, etc), and also a CSS file for users
viewing without
JavaScript (MediaWiki:Noscript.css).

Other changes
-- -------------

$wgEnableDublinCoreRdf and $wgEnableCreativeCommonsRdf no longer
work in core, and the functionality has been moved to the relevant
See and as appropriate

- ----
$wgUseTeX has been superseded by the Math extension. To re-enable
math conversion after upgrading, obtain the Math extension from SVN or from and add to LocalSettings.php:
require_once "$IP/extensions/Math/Math.php";

Language support
- ----------------

As with every release, MediaWiki 1.18 brings improved support for
languages in MediaWiki, with improved translation and features for
the many supported languages.

New languages:

* Angika (anp)
* Brahui (brh)
* Central Dusun (dtp)
* Jamaican Creole English (jam)
* Khowar (khw)
* Liv (liv)
* Kichwa (qug)

- ---

API bug fixes and new features have been added to 1.18, providing
more options for input and output.

* API modules were added to access QueryPage based special
pages, to Compare pages, Revert files, and to be able to access
other special pages such as Special:UnwatchedPages,
Special:MimeSearch and Special:ActiveUsers

* The output of the generated help page has been improved

The API contains a breaking changes against previous releases:

* action=watch now requires POST and token.
