 ## v0.16.0
 
+### New features
+
 * The `subctl cloud prepare azure` command has a new flag, `air-gapped`, to indicate the cluster is in an air-gapped
   environment which may forbid certain configurations in a disconnected Azure installation.
 * `subctl` is now built for ARM Macs (Darwin arm64).
 * `subctl show versions` now shows the version of the metrics proxy component.
-* Reduced data path downtime with Libreswan cable driver when gateway pod restarts.
-* Fixed an issue with OVNKubernetes CNI where routes could be accidentally deleted during cluster restart, or
-  upgrade scenarios.
-* Submariner now uses case-insensitive comparison while parsing CNI names.
 * The `subctl gather` command now collects metrics proxy pod logs in Globalnet deployments.
-* Submariner gateway pods now skip invoking cable engine cleanup during termination, as this is handled by the route agent
-  during gateway migration.
-* Fixed issue which caused the IPsec pluto process to crash when the remote endpoint was unstable.
-* Submariner now explicitly configures dpddelay when initiating IPsec connections to prevent excessively frequent
-  liveness probes.
-* The status condition type "Allocated" for Globalnet resources now adheres to the intended design of status conditions in
-  Kubernetes by reflecting only the latest observed status.
-* The Globalnet component now handles out-of-order remote endpoint notifications properly.
 * For headless services, Service Discovery now derives its `EndpointSlices` from the Kubernetes `EndpointSlices` so for each
   Kubernetes `EndpointSlice` there will be a corresponding Service Discovery `EndpointSlice`.  Service Discovery `EndpointSlices`
   follow the same naming convention in that the names are auto-generated by Kubernetes prefixed by the service name.
   Endpoints for all conditions are now included - prior releases only published ready endpoints.
 * Service Discovery will now publish DNS records for pods that are not ready based on the setting of the `publishNotReadyAddresses`
   flag on the service.
 * Service Discovery now propagates labels from an exported `Service` to its generated `EndpointSlices`.
-* Submariner now explicitly enables forwarding on the interfaces that it creates to support forwarding even when
-  global forwarding on the node is turned off.
-* Enhanced Calico CNI detection now includes searching for calico-node CNI pods when the calico-config map is not detected.
 * The new `subctl upgrade` command can upgrade `subctl` itself in-place, and upgrade Submariner deployments on brokers
   and joined clusters to the corresponding version of Submariner.
 * The `subctl diagnose` command has been enhanced to check for potential firewall issues that may be blocking ESP traffic
   and will provide an appropriate error message.
+* Submariner now explicitly enables forwarding on the interfaces that it creates to support forwarding even when
+  global forwarding on the node is turned off.

 * Fixed an issue with Service Discovery where a remote cluster's service was inaccessible after recreating its local namespace.
 * `subctl verify` no longer requires the KUBECONFIG environment variable to be set.
+* The Globalnet component now handles out-of-order remote endpoint notifications properly.
