The EKS Construct Library is an AWS CDK module that helps customers provision Amazon EKS clusters using infrastructure-as-code best practices. Up until now, it has been in an experimental state, incorporating lots of customer feedback and undergoing multiple API and behavioral changes. Starting from version 1.65.0 (https://github.com/aws/aws-cdk/releases/tag/v1.65.0), the library is graduating to Developer Preview. This means that we are not planning any breaking changes going forward and are preparing the library for GA.
