Version 5.0 is finally released and available for download at their site. Simply login and click on the Download icon to find it.
DotNetNuke 5.x is the "next generation" development branch of the DotNetNuke web application framework. DotNetNuke 5.x is available as a general public release which means it can reliably be used in a production environment.
Self promotion: If you need a book to help you learn then you can pre-order the DotNetNuke version 5 book from Wrox which I co-authored with Darrell Hardy, Stan Schultes and Ryan Morgan. Shaun Walker, chief Dnn Guru, wrote a chapter as well.
We are planning on having a DotNetNuke track for Code Camp. Will Strohl is putting it together. Stay tuned.
Let me know if you need training on DNN.
