Finally! After quite a lot of preparations, we're are live with "umbraco Pro" a supported version of umbraco. "We" are Per Ploug Hansen, Casey Neehouse and I, so that's a killer-team if you ask me.
umbraco Pro is a commercial license bundled with either three months or a year of support with guaranteed response time. Pricing starts at just €1.500 and details are in the feature matrix.
We're also in the process of getting the umbraco pro distribution certified by Microsoft, which should be ready by the end of the year.
umbraco Pro is not the end of the open source version of umbraco. It's a certified, supported alternative to the existing distribution which finally makes umbraco fully comparable to closed source products, but both editions are based on the same code base and that won't change. With "umbraco Pro" everybody wins. You can get answers to your umbraco questions, we can share our knowledge and finance the development of umbraco.
Go order ;-)
