Full release notes:

This release brings a number of CLI fixes and Controller improvements.

  • CLI
    • Fixed a bug that caused pods to crash after upgrade if
      --skip-outbound-ports or --skip-inbound-ports were used
    • Added unmeshed flag to the stat command, such that unmeshed resources
      are only displayed if the user opts-in
    • Added a --smi-metrics flag to install, to allow installation of the
      experimental linkerd-smi-metrics component
    • Fixed a bug in linkerd stat, causing incorrect output formatting when using
      the --o wide flag
    • Fixed a bug, causing linkerd uninstall to fail when attempting to delete
  • Controller
    • Improved the anti-affinity of linkerd-smi-metrics deployment to avoid
      pod scheduling problems during upgrade
    • Improved endpoints change detection in the linkerd-destination service, enabling
      mirrored remote services to change cluster gateways
    • Added operationID field to tap OpenAPI response to prevent issues during
      upgrade from 2.6 to 2.7
  • Proxy
    • Added a new protocol detection timeout to prevent clients from consuming
      resources indefinitely when not sending any data
As always, we're excited to hear your feedback! Please try out the new release and send questions/comments to us on this mailing list, and bugs via GitHub
