Improvements

  • Fixed a bug triggered by node restart causing Pods to receive incorrect configuration (Issue 20676).
  • Improved Istio CNI robustness. Previously, when a node restarted, new pods may be created before the CNI was setup, causing pods to be created without iptables rules configured (Issue 14327).
  • Fixed MCP metrics to include the size of the MCP responses, rather than just requests (Issue 21049).
