Upgrade Notes

Important changes operators must understand before upgrading to Istio 1.1.

Mar 19, 2019

This page describes changes you need to be aware of when upgrading from Istio 1.0.x to 1.1.x. Here we detail cases where we intentionally broke backwards compatibility. We also mention cases where backwards compatibility was preserved but new behavior was introduced that would be surprising to someone familiar with the use and operation of Istio 1.0.

For an overview of new features introduced with Istio 1.1, please refer to the 1.1 change notes.
