Dear Linkerd community, 

Linkerd 1.4.6 is released!

Linkerd 1.4.6 adds even more watch state endpoints to Linkerd's debugging arsenal, allowing you to inspect the state of Linkerd’s watches easily. This release adds watch state endpoints for the Kubernetes ConfigMap interpreter as well as the Marathon and filesystem namers.

Full release notes:

  • HTTP/1.1 and HTTP/2

    • Allow HTTP/1.1 and HTTP/2 POST requests to be retryable.

    • Fix an issue where the x-forwarded-client-cert header was not always cleared on incoming requests.

  • Add TLS support for the `io.l5d.etcd` namer client.

  • Admin

    • Add new io.l5d.marathon,  io.l5d.fs,  and  io.l5d.k8s.configMap watch state endpoints to allow diagnosis of Linkerd’s various watches.

  • Distributed Tracing

    • Add a new io.l5d.zipkin trace propagation plugin that writes Zipkin B3 trace headers to outgoing requests. Previously, Zipkin trace headers were ignored by Linkerd in order for Linkerd to not interfere with other tracing systems like Zipkin.

  • Namerd

    • Add an experimental io.l5d.destination interface which implements the Linkerd destination API.
