What’s New in Calico – Fall 2025 Release

Simplify, Secure, and Scale Your Infrastructure Resilient, High-Performance Networking High Availability (HA) Management Plane for VMs and Bare Metal Hosts Running Calico Official Release (GA) of the Nftables data plane for Calico Support for the Maglev Load Balancing in Calico for More Reliable Session Connectivity Simplified Operations and Visibility Support for Priority Markings in QoS Policies Dashboards and Observability for Calico Ingress Gateway Get Started with Calico Fall 2025 As organizations scale Kubernetes and hybrid infrastructures, many are realizing that more tools don’t mean better security. A recent Microsoft report found that organizations with 16+ point solutions see 2. 8x more data security incidents than those with fewer tools. Yet platform teams are still expected to deliver resilience and performance across containers, VMs, and bare metal, often while juggling fragmented tools that introduce risk, downtime, and complexity. The Fall 2025 release of Calico Enterprise and Calico Cloud cuts through that complexity. Its new features are designed to make your infrastructure more resilient, performant, and observable—right out of the box. From disaster recovery automation to modern data plane support and application traffic handling, these updates empower platform engineers to simplify operations while meeting strict reliability requirements. 1.
