- Fix for some long standing high-level consumer rebalance issues: [#423](https://github.com/SOHU-Co/kafka-node/pull/423)
- Fixed issue where consumers who weren't assigned a partition would never rebalance... ever

- If consumer joins or leaves a group during another consumers rebalance then that rebalancing consumer may miss owning partitions
