Istio 1.28.3 is a patch release that fixes several bugs to improve robustness. Key fixes include resolving goroutine memory leaks in ambient mode, addressing informer failures in ambient multicluster setups that previously required istiod restarts, and fixing NFT operation crashes and pod deletion failures. The release also adds a service.selectorLabels field to the gateway Helm chart for custom service selector labels during revision-based migrations.
