major feature:
This release included two major changes. First, a new API for configuring observers was introduced. This new API makes writing Fluo applications faster and easier. Also the new API supports using Java 8 Lambdas. Second, the efficiency of finding notifications was dramatically improved. This change allows Fluo to scale to much larger numbers of nodes.
