Istio 1.1 Helm Changes
Details the Helm chart installation options differences between Istio 1.0 and Istio 1.1.
The tables below show changes made to the installation options used to customize Istio install using Helm between Istio 1.0 and Istio 1.1. The tables are grouped in to three different categories:
- The installation options already in the previous release but whose values or descriptions have been modified in the new release.
- The new installation options added in the new release.
- The installation options removed from the new release.
