This is the first Istio release of 2022. We would like to thank the entire Istio community for helping to get Istio 1.13.0 published. Special thanks are due to the release managers Steven Landow (Google), Lei Tang (Google) and Elizabeth Avelar (SAP), and to Test & Release WG lead Eric Van Norman (IBM) for his help and guidance.
Here are some of the highlights of the release:
Configure the Istio sidecar proxy with the
Previous versions of Istio allowed configuration of proxy-level Envoy options with the mesh-wide settings API.
In 1.13, we have promoted this configuration to its open top-level custom resource,
ProxyConfig. Like other Istio
configuration APIs, this CR can be configured globally, per-namespace, or per-workload.
In the initial release, you can configure concurrency and proxy image type through the
ProxyConfig CR. This will
expand in future releases.

Continued improvements to the Telemetry API
We continue to refine the new Telemetry API, introduced
in Istio 1.11. In 1.13, we added support for logging with
OpenTelemetry, filtering access logs,
and customizing the trace service name. There are also a large number of bug fixes and improvements.
Support for hostname based load balancers for multi-network gateways
Up until now, Istio has relied on knowing the IP address for a load balancer used between two networks in an east-west configuration. The Amazon EKS load balancer provides a hostname instead of an IP address, and users had to manually resolve this name and set the IP address as a workaround.
In 1.13, Istio will now automatically resolve the hostname of a gateway, and Istio can now automatically discover the gateway of a remote cluster on EKS.
WorkloadGroup API feature, first
introduced in Alpha in Istio 1.8, has been promoted to Beta in this release.
Authorization policy dry-run mode has also been promoted from Experimental to Alpha.
Upgrading to 1.13
Please note that Istio 1.13.1 will be released on February 22 to address various security vulnerabilities.
When you upgrade, we would like to hear from you! Please take a few minutes to respond to a brief survey to let us know how we’re doing.
