Icon Istio 1.0.5

This release addresses some critical issues found by the community in prior releases. This release note describes what’s different between Istio 1.0.4 and Istio 1.0.5.

Fixes

  • 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.
