Today, Cuyahoga 1.6.0 is released. This is a maintenance release, mainly with improvements in the Admin UI.
See the release notes for a complete list of new features, improvements and bug fixes.  

Special thanks go out to Marco Trova for the admin UI improvements. Also thanks to Juan Wuoang and John Lynch for contributing to this release.

Go to the download page for the source and binary packages.

To anybody eagerly awaiting the Cuyahoga 2.0 release: work is progressing steadily. The new admin UI is more or less functional and we're now busy rewriting the core modules to leverage the content abstraction and create new module admin pages with ASP.NET MVC. When this piece is finished, we'll release Cuyahoga 2.0 Alpha.
If you're interested to see what it looks like, get the 2.0 sources from SVN and run the project from VS 2008 with the url http://localhost:8080/manager. Unlike some other .NET OS projects, we strongly advice NOT to use this code for production sites ;).
