Bug fixes

• StatefulProcessor doesn't properly recover state (#277)
• EventsourcedProcessor doesn't respect eventuate.log.write-batch-size (#329)

Dependency upgrades

• Scala 2.11.8
• Akka 2.4.12

Breaking changes

• Discontinue support for actor-level causality tracking (#280). The sharedClockEntry method has been removed from the public API. All EventsourcedActors that share a local event log
  • also share the same entry in the log-level (= server-side) vector clock
  • are guaranteed to receive events in the same order, both, during live processing and event replay
• API for local replication filters changed to distinguish between source log (defined by log name) and target log (defined by target log id) specific filters (#273). See scala doc of ReplicationEndpoint and EndpointFilters for details.
• DurableEvent(emitterId: String) constructor replaced by DurableEvent(payload: Any). That's a semantic change that is not detected by the compiler.
