Release Notes: This release added IPv6, clustering, and health checks for load balancer pools. When deployed with Erlang R14B, SSL termination works with both IPv4 and IPv6. Support for clustering listeners requires Cluster Supervisor 0.1. mod_cluster provides vip management for IPv4 and IPv6 vips by using the Cluster Supervisor application. Surrogate supports offloading stream filter processing work to worker nodes. TCP handshake health checks allow hosts to be dropped from load balancer pools. A configuration setting for how many times a pool is to be tried before giving up has also been added.
