Kgateway v2.1 has been released, introducing significant improvements and new features. The highlight is the integration of agentgateway, a scalable data plane for AI connectivity, which replaces the Envoy-based AI Gateway and Inference Extension. While agentgateway support is currently in beta, users can enable it easily with Helm. The implementation allows for better connections to LLMs and AI agents, streamlining traffic management across various workloads.
The update also brings full compliance with Kubernetes Gateway API version 1.3.0 and includes a feature for global policy attachment, allowing policies to function across different namespaces. Other enhancements include deep merging for authorization policies, customizable pod templates, and the introduction of Horizontal Pod Autoscaling (HPA). The Dynamic Forward Proxy (DFP) filter can now be configured to resolve upstream hosts dynamically, which simplifies proxy management.
New session affinity options improve how requests are handled. Users can choose different load balancing algorithms, implement consistent hashing, and ensure sticky sessions. Passive health checks with outlier detection enhance reliability by removing unhealthy services from traffic pools. A new operations dashboard for Grafana provides insights into performance metrics. The release also acknowledges the contributions of 42 contributors and the involvement of mentees from the LFX Mentorship Program, demonstrating a commitment to community and collaborative development.
