The month-by-month browsing has been improved by use of a drop-down selector to jump ahead or back by up to 3 months at a time (this number is configurable).  This is faster than the one month forward/back buttons that were used previously.

An image/logo/photo can be uploaded for each event now, and is displayed in the normal event preview.

Lastly, events can now be managed by regular members, if the web site allows it.  This is for community web sites in which the members can add their own events to a community calendar so that other members can see it.  The site owner is notified by email when events are added.
