summary
Gateway API 1.3 adds core support, retry budgets, listener sets and percentage/fractional request mirroring, and recommends returning a 421 to avoid TLS connection coalescing misroutes; Gateway tooling includes HPRoute migration helpers and a GatewayCTL UI for resource graphs. Ingress‑NGINX shifts to maintained-only and Ingating aims to replace it while Gateway covers roughly 35% to 55% feature parity with work needed. kube‑proxy moves nftables GA in 1.33 (opt‑in), connection tracking and topology‑aware routing improve. NetworkPolicy exposes cluster‑scoped admin CRDs (alpha), plans to merge CRDs, add ICMP, tenants, and a Policy Assistant tool. Multi‑NIC uses Dynamic Resource Allocation.
