A new WordPress version has been released just a minute ago. The new release brings the popular blogging platform to version 3.4.1. Webmasters and administrators should see notifications in the admin dashboard that a new version is available. From here they have the options to install the update right from within the admin dashboard, or to download the release to a local system for testing and manual updating purposes. It is as always recommended to backup the blog, files and database, before installing the update on the server.
WordPress 3.4.1 is a maintenance and security update according to the official release page. The new version fixes 18 bugs in WordPress that were discovered in version 3.4 which has been released exactly two weeks ago (see WordPress 3.4 release announcement).
The new version of WordPress in addition fixes several security related issues and hardens the security of the software further. Andrew Nacin on behalf of the WordPress team revealed that these vulnerabilities could potentially be used for information disclosure and affected multi-site installs with untrusted users as well.
As far as resolved bugs are concerned, they are all listed on the WordPress Tracker website.
It is recommend to update blogs running WordPress to the newest version as soon as possible because of the security issues that it addresses.
I have updated several of the blogs that I administrate and have not seen any bugs or ill-effects caused by the update. While that is no guarantee that this will also be the case on other updated sites, it is likely that only a minority will run into issues with this update.
