This is the fourth Istio release of 2022. We would like to thank the entire Istio community for helping to get Istio 1.16.0 published. Special thanks are due to the release managers Daniel Hawton from, Ziyang Xiao from Intel, and Tong Li from IBM. As always, our gratitude goes to Test & Release WG lead Eric Van Norman (IBM) for his help and guidance.

What’s new

Here are some of the highlights of the release:

External Authorization Promoted to Beta

Istio’s External Authorization feature has been promoted to Beta. For more information, see the External Authorization documentation.

Kubernetes Gateway API Implementation Promoted to Beta

Istio’s implementation of the Gateway API has been promoted to Beta. This is a significant step toward our goal of making the Gateway API the default API for traffic management in the future.

Along with the Beta promotion, we have enhanced all of our ingress tasks to include parallel instructions for configuring ingress using either the Gateway API or the Istio configuration API. Also, although using the Gateway API for more generally configuring internal mesh traffic is still an experimental feature of the Gateway API, pending upstream agreement, several other Istio documents have been updated with Gateway API instructions to allow early experimentation. Refer to the Gateway API task for more information.

JWT Claim Based Routing Promoted to Alpha

Istio’s JWT Claim Based Routing feature has been promoted to Alpha. For more information, see the JWT Claim Based Routing documentation.

HBONE for Sidecars and Ingress (Experimental)

We have added support for the HBONE protocol for Sidecars and Ingress gateways. For more information, see the pull request.

MAGLEV Load Balancing Support

We have added support for the MAGLEV load balancing algorithm. For more information, see the Envoy Documentation.

Added OpenTelemetry Tracing Provider Support

We have added support for the OpenTelemetry tracing provider with the Telemetry API.
