MediaWiki 1.20
MediaWiki 1.20 is a stable release.
PHP 5.3 now required
Since 1.20, the lowest supported version of PHP is now 5.3.2. Please upgrade PHP if you have not done so prior to upgrading MediaWiki.
Configuration changes in 1.20
$wgGitRepositoryViewers defines a mapping from Git remote repository to the Gitweb instance URL used in Special:Version.
$wgUsePathInfo = true; is no longer needed to make $wgArticlePath work on servers using like nginx, lighttpd, and apache over fastcgi. MediaWiki now always extracts path info from REQUEST_URI if it's available.
The user right 'upload_by_url' is no longer given to sysops by default. This only affects installations which have $wgAllowCopyUploads set to true.
Removed f-prot support from $wgAntivirusSetup.
New variable $wgDBerrorLogTZ to provide dates in the error log in a different timezone than the wiki timezone set by $wgLocaltimezone.
New variables $wgDBssl and $wgDBcompress to enable SSL and compression for database connections, if either are available for the selected DB type.
$wgUseCombinedLoginLink now defaults to false, making MediaWiki output separate login and create account links by default.

2011-11-24
This a maintenance and security release of the MediaWiki 1.17 branch.
=== Security changes ===
* (bug 32276) Skins were generating output using the internal page title which
would allow anonymous users to determine wheter a page exists, potentially
leaking private data. In fact, the curid and oldid request parameters would
allow page titles to be enumerated even when they are not guessable.
* (bug 32616) action=ajax requests were dispatched to the relevant internal
functions without any read permission checks being done. This could lead to
data leakage on private wikis.

Summary of selected changes in 1.17
Selected changes since MediaWiki 1.16 that may be of interest:
A new installer has been introduced. It has a wizard-style interface which is translated into many languages. Many shortcomings in the old installer were addressed with this rewrite. Note that it is no longer required for the config directory to be made writable by the webserver. Instead the generated LocalSettings.php file is offered as a download, which you must then upload to the wiki's base directory.
ResourceLoader, a new framework for delivering client-side resources such as JavaScript and CSS, has been introduced. These resources are now delivered through the new entry point script "load.php", instead of as static files served directly by the web server. This allows minification, compression and client-side caching to be used more effectively, which should provide a net performance improvement for most users.
Category sorting has been improved.
Sorting is now case insensitive.
Sub-categories, pages and files can now be paged separately.
When several pages are given the same sort key, they sort by their names instead of randomly.
The lowest supported version of PHP is now 5.2.3. If necessary, please upgrade PHP prior to upgrading MediaWiki.
Summary of selected changes in 1.16
Selected changes since MediaWiki 1.15 that may be of interest:
Watchlists now have RSS/Atom feeds. RSS feeds generally are now hidden, since Atom is a better protocol and is supported by virtually all clients.
It's now possible to block users from sending email via Special:Emailuser.
The maintenance script system was overhauled. Most maintenance scripts now have a useful help page when you run them with --help.
AdminSettings.php is no longer required in order to run maintenance scripts. You can just set $wgDBadminuser and $wgDBadminpassword in your LocalSettings.php instead.
The preferences system was overhauled. Preferences are stored in a more compact format. Changes to site default preferences will automatically affect all users who have not chosen a different preference.
Support for SQLite was improved. Some broken features were fixed, and it now has an efficient full-text search.
The user groups ACL system was improved by allowing rights to be revoked, instead of just granted.
A new localisation caching system was introduced, which will make MediaWiki faster for almost everyone, especially when lots of extensions are enabled.
By default, this new system makes a lot of database queries. If your database is particularly slow, or if your system administrator limits your query count, or if you want to squeeze as much performance as possible out of Mediawiki, set $wgCacheDirectory to a writable path on the local filesystem. Make sure you have the DBA extension for PHP installed, this will improve performance further.

== MediaWiki 1.15.5 ==
2010-07-28
This is a security and maintenance release.
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

This is a security and bugfix release of MediaWiki 1.15.4.
Two security vulnerabilities were discovered.
Kuriaki Takashi discovered an XSS vulnerability in MediaWiki. It
affects Internet Explorer clients only. The issue is presumed to
affect all recent versions of IE, it has been confirmed on IE 6 and 8.
Noncompliant CSS parsing behaviour in Internet Explorer allows
attackers to construct CSS strings which are treated as safe by
previous versions of MediaWiki, but are decoded to unsafe strings by
Internet Explorer. Full details can be found at:
https://bugzilla.wikimedia.org/show_bug.cgi?id=23687
A CSRF vulnerability was discovered in our login interface. Although
regular logins are protected as of 1.15.3, it was discovered that the
account creation and password reset features were not protected from
CSRF. This could lead to unauthorised access to private wikis. See
https://bugzilla.wikimedia.org/show_bug.cgi?id=23371 for details.
These vulnerabilities are serious and all users are advised to
upgrade. Remember that CSRF and XSS vulnerabilities can be used even
against firewall-protected intranet installations, as long as the
attacker can guess the URL.

This is a security and bugfix release of MediaWiki 1.15.3 and MediaWiki
1.16.0beta2.
MediaWiki was found to be vulnerable to login CSRF. An attacker who
controls a user account on the target wiki can force the victim to log
in as the attacker, via a script on an external website. If the wiki is
configured to allow user scripts, say with "$wgAllowUserJs = true" in
LocalSettings.php, then the attacker can proceed to mount a
phishing-style attack against the victim to obtain their password.
Even without user scripting, this attack is a potential nuisance, and so
all public wikis should be upgraded if possible.
Our fix includes a breaking change to the API login action. Any clients
using it will need to be updated. We apologise for making such a
disruptive change in a minor release, but we feel that security is
paramount.
For more details see https://bugzilla.wikimedia.org/show_bug.cgi?id=23076

Two security issues were discovered:
A CSS validation issue was discovered which allows editors to display
external images in wiki pages. This is a privacy concern on public
wikis, since a malicious user may link to an image on a server they
control, which would allow that attacker to gather IP addresses and
other information from users of the public wiki. All sites running
publicly-editable MediaWiki installations are advised to upgrade. All
versions of MediaWiki (prior to this one) are affected.
A data leakage vulnerability was discovered in thumb.php which affects
wikis which restrict access to private files using img_auth.php, or
some similar scheme. All versions of MediaWiki since 1.5 are affected.
Deleting thumb.php is a suitable workaround for private wikis which do
not use $wgThumbnailScriptPath or $wgLocalRepo['thumbScriptUrl'].
Alternatively, you can upgrade to MediaWiki 1.15.2 or backport the
patch below to whatever version of MediaWiki you are using.

Note: Version 1.13.5 did NOT have the XSS vulnerability...

This is a maintenance release which corrects some bugs in the installer,
introduced during the hasty security release of 1.13.4. It is not
necessary to upgrade if you do not intend on using the installer.
|
|
A number of cross-site scripting (XSS) security vulnerabilities were
discovered in the web-based installer (config/index.php). These
vulnerabilities all require a live installer -- once the installer has been
used to install a wiki, it is deactivated.
Note that cross-site scripting vulnerabilities can be used to attack any
website in the same cookie domain. So if you have an uninstalled copy of
MediaWiki on the same site as an active web service, MediaWiki could be used
to attack the active service. If you are hosting an old copy of MediaWiki
that you have never installed, we advise you to remove it from the web.
|
|
This is a security release of MediaWiki 1.13.3. Some of the security issues
affect *all* versions of MediaWiki except the versions released today, so
all site administrators are encouraged to upgrade.
