v1.3.0
02c862e

We are delighted to present version 1.3.0 of Contour, our layer 7 HTTP reverse proxy for Kubernetes clusters.

All Contour users should upgrade to Contour 1.3.0 and Envoy 1.13.1.

New and improved

Contour 1.3.0 includes several new features as well as the usual smattering of fixes and minor improvements.

Removed the --use-extensions-v1beta1-ingress flag

The --use-extensions-v1beta1-ingress flag was removed from the contour serve command. If you have a previous deployment that specifies this command, you must remove it or Contour will fail to start.

PR: #2303
Thanks @davechaney

Renamed the tcpproxy.include field to be singular

The TCPProxy field has only ever supported including a single child document. In order to make this clearer, the includes field is now named include. The includes field is deprecated.

PR: #2201
Thanks @stevesloka

Reject HTTPProxies that lack at least one Service per route

The rule that Route field must reference at least one Service is now enforced.

PR: #2332
Thanks @davecheney

Improved graceful shutdown

Contour now does a better job of gracefully shutting down when it receives SIGINT or SIGTERM.

PR: #2350
Thanks @davecheney
