About Istio

Istio's Ambient mesh hits multi-network beta and the project is unwinding from Google-hosted artifacts.

Recent activity is split across three threads: technical posts (wildcard egress design, namespace multi-tenancy security guidance, and ambient multi-network multicluster reaching beta), governance work (2026 Steering Committee election results, KubeCon EU planning), and infrastructure (announcement that Istio images will leave gcr.io/istio-release by January 2027 due to changes in funding). Release-cadence-wise, the substantive product release in this slate is ambient multi-network multicluster moving to beta in 1.29.
