I released 3.4.0.Beta1 yesterday. It contains delta views [1] and
compressed merge views [2]. Useful in large clusters, delta views
dramatically reduce the message size needed to install a new view, by
sending only the diff to the previous view. E.g. if we have
v5=

and F joins, A will only send v6=

, and everybody
will construct a new view v6=

.

The message size of a new view is therefore only a function of the
number of members which joined or left, and not a function of the entire
cluster size.

Full views are only sent when the first view of a coordinator is sent,
e.g. if A crashes and B takes over, B would send the full view.

Delta views can be turned off by seting GMS.use_delta_views=false.

3.4.0.Beta1 can be downloaded from SourceForge [3] or Nexus [4].

3.4.0.Beta1 should be the last (and only) beta, I intend to release
3.4.0.Final in early October.
