### Terraform Version ```shell [ec2]$ terraform version Terraform v0.14.11 Your version of Terraform is out of date! The latest version is 1.14.3.

Has anyone tried like this in EKS Module 17.24 (That is making use of Amazon Linux 2023 as worker node OS) 2. Is this a recommended approach for bringing AL2023 for my worker nodes ? 3. Do we have any specific version of EKS module that we need to strictly follow inorder to make of AL2023 ? if so, then can you please let us know the version name ? ### Actual Behavior Not Sure (N/A) ### Steps to Reproduce NA ### Additional Context Aim :- 1)Migrating Node Group OS from AL2 to AL2023 2) Looking for an suggestion if we can achieve this via 17.24.0 3) If we make use of 17.24.0 EKS module version, do we need to worry about any unexpected behavior of my eks cluster ? ### References _No response_ ### Generative AI / LLM assisted development? _No response_
