In the last two weeks, we have added a lot of pages to the cinnamon website with the goal to increase the quality of the project's documentation. Visit http://cinnamon-cms.de to have a look, especially in the Cinnamon server section.
Today the first package of the Cinnamon CMS was released: the Server along with a basic java client library.
While Cinnamon has been in production use for some time (creating technical documentation for the automotive sector), we never got around to release packages of the code which exists in the Subversion repository. But that's about to change. A new open source desktop client is in the works, as well as an update to the project's homepage.
