Icon Istio 1.0.4

This release addresses some critical issues found by the community when using Istio 1.0.3. This release note describes what's different between Istio 1.0.3 and Istio 1.0.4.

Known issues

  • Pilot may deadlock when using istioctl proxy-status to get proxy synchronization status. The work around is to not use istioctl proxy-status. Once Pilot enters a deadlock, it exhibits continuous goroutine growth eventually running out of memory.


  • Fixed the lack of removal of stale endpoints causing 503 errors.

  • Fixed sidecar injection when a pod label contains a /.

Policy and telemetry

  • Fixed occasional data corruption problem with out-of-process Mixer adapters leading to incorrect behavior.

  • Fixed excessive CPU usage by Mixer when waiting for missing CRDs.
