This release strengthens the network foundation and adds new capabilities for teams running on Cycle. Inter-node IPsec now rolls encryption keys more often and handles high-throughput links better. The native load balancer responds much faster to route, instance, and DNS changes in large environments. The release also introduces an integrated, highly available message bus for pub/sub within your environments, and External Volumes now support AWS EBS volumes natively. Rounding out the release are HTTP/2 improvements across the load balancer and internal API, simpler traffic splitting, and more control over pipelines and virtual machines.
