+## [v12.0.0] - 2020-05-09
+BUG FIXES:
+- Fix Launch Templates error with aws 2.61.0 ([#875](https://github.com/terraform-aws-modules/terraform-aws-eks/issues/875))
+- Use splat syntax for cluster name to avoid `(known after apply)` in managed node groups ([#868](https://github.com/terraform-aws-modules/terraform-aws-eks/issues/868))
+
+DOCS:
+- Add notes for Kubernetes 1.16 ([#873](https://github.com/terraform-aws-modules/terraform-aws-eks/issues/873))
+- Remove useless template provider in examples ([#863](https://github.com/terraform-aws-modules/terraform-aws-eks/issues/863))
+
+FEATURES:
+- Create kubeconfig with non-executable permissions ([#864](https://github.com/terraform-aws-modules/terraform-aws-eks/issues/864))
+- Change EKS default version to 1.16 ([#857](https://github.com/terraform-aws-modules/terraform-aws-eks/issues/857))
+
+ENHANCEMENTS:
+- Remove dependency on external template provider ([#854](https://github.com/terraform-aws-modules/terraform-aws-eks/issues/854))
+
+BREAKING CHANGES:
+- The default `cluster_version` is now 1.16. Kubernetes 1.16 includes a number of deprecated API removals, and you need to ensure your applications and add ons are updated, or workloads could fail after the upgrade is complete. For more information on the API removals, see the [Kubernetes blog post](https://kubernetes.io/blog/2019/07/18/api-deprecations-in-1-16/). For action you may need to take before upgrading, see the steps in the [EKS documentation](https://docs.aws.amazon.com/eks/latest/userguide/update-cluster.html). Please set explicitly your `cluster_version` to an older EKS version until your workloads are ready for Kubernetes 1.16.
