This release note describes what’s different between Istio 1.19.0 and 1.19.1.
{{< relnote >}}
Added the ability to install the Gateway Helm chart with a dual-stack service definition.
Added a new configuration to ProxyConfig and ProxyHeaders. This allows customization of headers like server, x-forwarded-client-cert, etc. Most notably, these can now be disabled so that they are not modified.
Added a new configuration to ProxyHeaders and MetadataExchangeHeaders. The IN_MESH mode ensures x-envoy-peer-metadata and x-envoy-peer-metadata-id
headers will not be added to outbound requests from sidecars to destination services considered mesh external.
