Kong Mesh and Kuma 2.2 introduces several new enterprise features and improvements, including enhanced UI and policy functionalities, alongside bug fixes. Key upgrades include a new global rate-limiting service requiring an external Redis installation, support for OpenTelemetry in access logs and traces, and the introduction of a "Universal on K8s" deployment mode with Postgres for increased resiliency across multiple regions. The release also features a new MeshLoadBalancing policy for detailed load balancing configurations, improved security with offline token signing, and enhanced RBAC views in the UI. These additions aim to provide users with more flexibility, scalability, and security, while suggesting an easy upgrade process through kumactl or Helm.
