Oct 1, 2025October 2025—deckhouse/deckhouse: Delivered two focused changes that significantly enhance network tunability and maintenance hygiene. Implemented per-node MTU configuration for CNI-Cilium, enabling per-node MTU overrides via cilium-dbg build-config. Cleaned up Istio integration by removing obsolete CRDs for Istio v1.12 and v1.13 to streamline the module. These changes improve network performance tuning options, reduce configuration drift, and pave a cleaner upgrade path for Istio-related components.
