Reviews for this release

An excellent release that builds on the previous versions. Stable and easy to use. Powerful and simply laid out. It is less confusing than Umbraco and world's better than DNN.

Moving from 3.0 til 3.1 makes me very happy! The new Build Manager that its the heart for us more hardcore developers is much more stable and quirks are smoothed out so i can give C1 a big five stars again.
