WordPress 3.0.5 (and 3.1 Release Candidate 4)
Posted February 7, 2011 by Andrew Nacin. Filed under Releases,
Security,Testing.

WordPress 3.0.5 is now available and is a security hardening update
for all previous WordPress versions.

This security release is required if you have any untrusted user
accounts, but it also comes with important security enhancements
and hardening. All WordPress users are strongly encouraged to update.

Three point oh point five
Enhances security
Three point one comes soon

The release addresses a number of issues and provides two additional
enhancements:

Two moderate security issues were fixed that could have allowed a
Contributor- or Author-level user to gain further access to the site.

One information disclosure issue was addressed that could have
allowed an Author-level user to view contents of posts they
should not be able to see, such as draft or private posts.

Two security enhancements were added. One improved the security
of any plugins which were not properly leveraging our security API.
The other offers additional defense in depth against a vulnerability
that was fixed in previous release.

Thanks to Nils Jueneman and Saddy for their private and responsible
disclosures to security@wordpress.org for two of the issues. The
others were reported or repaired by our security team.

Download 3.0.5 or update automatically from the Dashboard > Updates
menu in your site’s admin area. Please update immediately.

WordPress 3.1 Release Candidate 4 is also now available.

The Release Candidate 4 build includes the security fixes and
enhancements included in 3.0.5 and addresses about two dozen
additional bugs. This includes fixes for:

    * Deleting a user and reassigning their posts to another user.
    * Marking multiple users or sites as spam in multisite.
    * PHP4 compatibility.

As outlined in previous RC posts, if you are testing the release
candidate and think you’ve found a bug, there are a few ways to
let us know:

    * Post it to the Alpha/Beta area in the support forums
    * Report it to the wp-testers mailing list
    * Join the development IRC channel and tell us live at irc.freenode.net #wordpress-dev
    * File a bug ticket on the WordPress Trac

To test WordPress 3.1, try the WordPress Beta Tester plugin
(you’ll want “bleeding edge nightlies”). Or you can download
the release candidate here (zip). If any new issues become known,
you’ll be able to find them here.

After nearly five months of development and testing, we think
we’re very close to a final release. Users and developers,
please test your themes and plugins.

Download WordPress 3.1 RC4 or WordPress 3.0.5 now.
