Instant OGo 1.1.0 got released. The product provides an inexpensive CD which installs a complete OpenGroupware.org server. It is probably the easiest way to get an up-to-date OGo installation including a mail server and more.
This release contains plenty of new features based on a QAed branch of OGo 1.1. Some of the highlights are role support for event attendees, extended appointment attributes and improved inter-object linking.
