Status of Istio 1.1


Hey, Istio Community -

I just wanted to write a quick note on the status of the 1.1 release.

Ever since the release of Istio 1.0, we’ve had a flood of adoption and, not surprisingly, a bunch of critical issues. This was expected, of course – for a project of this magnitude, we knew that a wave of adoption would mean a wave of bugs filed.

Addressing those issues so that people could reliably deploy 1.0 in production environments has been our focus for the last several months. Work on 1.1 has continued, but we’ve had to put more effort than we would have hoped going into the 1.0.x patch releases, which has pushed back the 1.1 delivery date.

The major themes for 1.1 are:

  • Scalability: improving the performance of Pilot and the Envoy proxies for meshes with thousands of services
  • Multi-cluster mesh: various features, including the implementation of Galley, a new top-level config ingestion, processing and distribution component.
  • Upgrades: ensuring that people who have adopted 1.0 can smoothly upgrade to newer versions as they come out

The final release timeline for 1.1 is not finalized, but we have begun the release qualification process. We expect to have our first release candidate later this month and a final build sometime in February.


Thanks for the updates.
You haven’t mentioned Istio CNI (, it will be in 1.1 release ?


Yes good reminder, it is planned to be as an experimental feature in v1.1.


What about the last 1.1 snapshot release? I see here:

that there is a snapshot 4 - but its in “draft”. When I try to download it, getLatestIstio fails:

I can confirm that, the 1.1 last snapshot release is not uploaded to github.

But you can download it from:
