CityDesk 2.0 is now shipping. Check out the full list of what's new in 2.0.
Fog Creek is no longer making a Home version of CityDesk, but they do still have the free Starter Edition (for sites up to 50 pages).
There is also a new Contributor Edition which provides 3 user licenses for the price of 1 Professional Edition license, but without Designer Mode. This is a great money-saver for teams that have only one designer but several people that need to add, edit and delete articles.
