Right now Kentico CMS partners can login to the Partner Portal and download the beta version of Kentico CMS 6.0. The beta of 6.0 is intented for testing only.
I'm downloading/installing it right now, and I can't wait to get it up and running to see all the new features. For more on what to expect check out the great post by Jeroen Furst a Kentico MVP and his review of the 6.0 CTP.
I'm extremely happy to see the Web Application option in the installer.
Notice the new Register Performance Counters for Health Monitoring
I also love the ability to install or not install every Module under the sun.
After this it was the normal installer and progress bar screens.
Now to dive in for real. I'll make another post later on my impression on the new features.
Update: I had to add the new login screen. It looks GREAT.
