[infinispan-dev] JGroups 3.4.0.Beta1

FYI, 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={A,B,C,D,E} and F joins, A will only send v6={v5 +F}, and everybody will construct a new view v6={A,B,C,D,E,F}. 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.
