Linkerd 1.6.3 includes a bug fix for Namerd's io.l5d.k8s dtab storage module. This fix exposes
HTTP request and response metrics for the Kubernetes API client used to store dtabs. Namerd also
includes a new logging dashboard page that allows you to change Namerd's logging verbosity at
runtime. In addition, this release improves Linkerd's HTTP/2 implementation to better manage direct
memory and includes a fix for Linkerd's interpreter_state watch state endpoint.

A special thank you to the following contributors for their awesome doc update contributions:

Full release notes:

  • Namerd
    • Expose HTTP client metrics for Namerd's io.l5d.k8s dtab storage module. This change now
      instruments the HTTP client that interacts with the Kubernetes API used for storing dtabs.
    • Adds a new logging dashboard page in Namerd with the ability to change logging verbosity at
      runtime. This is similar to Linkerd's logging dashboard page
  • HTTP/2
    • Fixes an issue where Linkerd could sometimes exhaust direct memory when routing HTTP/2 requests
      that immediately receive a RST_STREAM frame.
  • Fixes a BufferUnderflowException that could be triggered when viewing Linkerd's
    interpreter watch state endpoint. This issue occurs when using Linkerd's io.l5d.namerd thrift
    interpreter.
  • Fixes an issue where Linkerd incorrectly uses the JVM's Parallel GC collector if the GC_LOG
    start-up flag is not set on JVMs using Java 1.8 or earlier.
