The team over at Umbraco have released version 4 of their content management system. If you fancy trying out a .NET system, then check it out. We're going to be reviewing it within the coming days.
From their site:
"The ultra solid release of Umbraco is raising the bar in the Web CMS industry. The stability, the clean and user friendly UI, the beautiful and simple Canvas editing, the inclusion of community work, the integration to the .NET framework and the absolutely control over markup is second to none."
