v1.16.3
IMPORTANT: v1.16.3 contains a regression (#2807) that may lead to high CPU consumption by the aws-node pod when the maximum number of ENIs have been attached to a node. This bug is being addressed in v1.16.4.
Release Notes
- With this release, the Network Policy agent image is updated to v1.0.8.
- With this release, the VPC CNI now supports IPv4 clusters where only a subset of nodes enable IPv6 egress (instead of all).
