v2.5.0 IPv6 support, non-breaking changes expected

Upgrading to this version, if you have node_role_cni_policy_enabled set to true (the default), will cause a new IAM policy to be created and your existing node group IAM role to have its permissions updated. This will cause a transient interruption in the ability of the node to manage its network interface, but it should heal itself with no interruption to existing services. It may cause a short (some seconds) delay in being able to deploy new Pods.

what

• Update node group IAM role permissions to support IPv6

why
