Kuma 1.4 and Kong Mesh 1.5 have been released, featuring over 25 new enhancements aimed at improving performance and functionality, particularly for large-scale service mesh deployments. Notably, Kong Mesh introduces native Role-Based Access Control (RBAC) across Kubernetes and virtual machine environments, including Windows, to enhance operational scalability by restricting user permissions. The releases also showcase significant performance upgrades, such as the ability to manage twice as many data plane proxies with reduced CPU usage, and improvements to zone management within the dashboard interfaces. These updates are part of an ongoing effort to address potential performance issues by optimizing database interactions and resource consumption, with a strong emphasis on scalability and efficiency.
