RabbitMQ 4.1 is around the corner (update: has been released) and, as usual, apart from new features, we have made some internal changes that should provide better performance.

There are at least 4 notable changes:

1. Lower and more stable memory usage for quorum queues
2. Much better performance when consuming a long quorum queue
3. Better performance for Websocket connections
4. Lower memory usage and/or higher throughput for TCP connections

RabbitMQ 4.1 includes a completely redesigned peer discovery plugin for Kubernetes. No configuration changes should be needed when upgrading to 4.1, so if you want, you can just stop reading here.
