Platform/SRE — Learn: Cilium is a core CNI/eBPF network policy component that platform engineers operate directly; a new minor GA release warrants reviewing the full changelog for breaking changes or notable capabilities, but the summary is too thin to justify a planned upgrade without knowing what changed.

Cilium 1.20.0 released with Gateway API v1.6.1 and breaking changes

Mon, 03 Aug 2026 14:33:55 +0000

Platform/SRE — Plan: Cilium 1.20.0 is a substantial GA minor release for a core CNI component; before upgrading, audit whether your cluster uses legacy Mutual Authentication, Envoy Go extensions, Kafka-aware policies, the cilium.io/v2alpha1 CiliumNodeConfig API, libnetwork, or custom CNI configs — all require migration steps per the upgrade guide. No forced-upgrade deadline exists, so schedule evaluation this quarter.
