Checked this post and found an info about EventBus http://www.tigase.net/blog-entry/tigase-server-700-release
Is there some documentation or some explanation what is this and how people can use it?

We are working on documentation and example code for all new elements. In summary, this is kind of a PubSub inside the Tigase core code. All the Tigase components and plugins can publish stuff to this PubSub nodes and any other components or even XMPP entities can subscribe to receive notifications form these nodes. This opens whole new applications and ways the Tigase can be extended, monitored and interact with... "the whole world" :-)
