Linkerd 1.1.3 Released!


We’re very excited to announce that Linkerd 1.1.3 has been released! This release is mostly focused on improving our HTTP/2 support, including better support for gRPC. Linkerd now supports automatic retries in HTTP/2 for retryable requests.

You can download it from the releases page or get the docker image from docker hub. Full release notes are below:

  • HTTP/2
    • Cleaned up spurious errors messages in the Linkerd log output.
    • Added a number of gRPC response classifiers that use the grpc-status code
      to determine if the response was successful and if it should be retried.
      See the docs for details.
    • Added support for failure accrual and automatic retries to HTTP/2.
    • Fixed a memory leak related to messages with only a headers frame.
  • Istio
    • Added HTTP/2 support to the Istio integration: the io.l5d.k8s.istio
      identifier can now be used in H2 router configs.
    • Added support for HTTPRedirect Route Rules.
  • The Linkerd and Namerd admin sites can now be configured to require HTTPS.
