Ivan Sim

Dear Linkerd community,

This is an edge release of Linkerd! The latest stable release is stable-2.4.0.

To install this edge release, run: curl | sh

  • CLI
    • Improved the installation report produced by the linkerd check command
      to include the control plane pods' live status
    • Added the --all-namespaces (-A) option to the linkerd get,
      linkerd edges and linkerd stat commands to retrieve resources across
      all namespaces
  • Controller
    • Fixed an issue with discovering StatefulSet pods via their unique hostname
    • Fixed an issue with traffic split where outbound proxy stats are missing
    • Bumped Prometheus to 2.11.1
    • Bumped Grafana to 6.2.5
    • Upgraded the service profile CRD to v1alpha2 where the openAPIV3Schema

      required for users currently using v1alpha1

      running as root in the CNI mode (thanks @codeman9!)
    • Introduced cluster heartbeat cron job
