v1.5.0 Release
This release improves the CNI behavior when the number of IPs available to the cluster is constrained. Setting a WARM_IP_TARGET will now return IPs that are not assigned to pods back to the subnet.
Note! Setting a low WARM_IP_TARGET will increase the number of calls being made to EC2, and if the cluster is large, or the pod churn high, there is a risk of getting throttled. If that happens, no ENIs or IPs will be available untill the throttling stops.
The EKS team wishes to express appreciation to the FICO engineering team for their collaboration on this release.
Also thanks to our external contributors @forsberg, @venkatesh-eb, @Zyqsempai and @bboreham that have contributed to this release.
