One-click installation of WordPress 3.0.1 is now available for Websoftnet web hosting customers. To install, simply log into your eXtend control panel and scroll down to ‘CGI Scripts’ for a one-click install and set up of your WordPress blog.
Customers with Windows hosting still have WordPress 2.9.2 as their one-click WordPress install, but we are looking to update this in the next few weeks).
As well as replacing WordPress 2.9.2, WordPress 3.0 also replaces WordPress MU (the multi-user version), as the multi-user features have been merged into WP as standard. Other new features in WordPress 3.0 include custom post types, unique author templates (great for multi-user blogs), improved menu management, a new default theme and support for the wp.me URL shortener. You can check out the complete list of the hundreds of new features and improvements in the WordPress 3.0 codex.
If you’re wondering about how to take advantage of some of these features, How to: Enable WordPress 3.0 New Features After Upgrading has lots of great links to help you get started.
