Announcing Istio 1.0.5

Patch Release

We’re pleased to announce the availability of Istio 1.0.5. Please see below for what’s changed.


  • Disabled the precondition cache in the istio-policy service as it lead to invalid results. The cache will be reintroduced in a later release.

  • Mixer now only generates spans when there is an enabled tracespan adapter, resulting in lower CPU overhead in normal cases.

  • Fixed a problem that could lead Pilot to hang.
