 ## Post-v1.14.0
 
+- IPPool
+  - Multiple IPPools now can bind to the same Namespace. [#5731](https://github.com/kubeovn/kube-ovn/pull/5731)
+  - Pods in a bound namespace will only get IPs from the bound pool(s), not other ranges in the subnet. [#5731](https://github.com/kubeovn/kube-ovn/pull/5731)
 - `AdminNetworkPolicy` now supports specify egress peers using FQDNs. [#5703](https://github.com/kubeovn/kube-ovn/pull/5703)
 - Using ARP for IPv4 network ready check: now you don't need ACL allow rules for gateway to make Pod running. [#5716](https://github.com/kubeovn/kube-ovn/pull/5716)
 - Non-primary CNI mode: you can run Kube-OVN as the secondary only network, without annoying unused annotations and logical switch port allocations. [#5618](https://github.com/kubeovn/kube-ovn/pull/5618)
 - VPC NAT Gateway:
+  - No default EIP mode: the secondary interface can initialize without a default EIP to avoid the waste. [#5605](https://github.com/kubeovn/kube-ovn/pull/5605)
   - Custom routes: you can control the route rules within the vpc-nat-gateway Pods to control traffic paths. [#5608](https://github.com/kubeovn/kube-ovn/pull/5608)
   - Gratuitous ARP: VPC NAT Gateway automatically sends gratuitous ARP packets during initialization to accelerate network convergence. [#5607](https://github.com/kubeovn/kube-ovn/pull/5607)
 - Healthchecks for static endpoints in `SwitchLBRules`: SLR with both selector or endpoints key can support healthchecks. [#5435](https://github.com/kubeovn/kube-ovn/pull/5435)
