+## [v13.1.0] - 2020-11-02
+FEATURES:
+- Add Launch Template support for Managed Node Groups ([#997](https://github.com/terraform-aws-modules/terraform-aws-eks/issues/997))
+- Add `cloudwatch_log_group_arn` to outputs ([#1071](https://github.com/terraform-aws-modules/terraform-aws-eks/issues/1071))
+- Add kubernetes standard labels to avoid manual mistakes on the managed `aws-auth` configmap ([#989](https://github.com/terraform-aws-modules/terraform-aws-eks/issues/989))
+
+CI:
+- Use ubuntu-latest instead of MacOS for docs checks ([#1074](https://github.com/terraform-aws-modules/terraform-aws-eks/issues/1074))
+- Fix GitHub Actions CI macOS build errors ([#1065](https://github.com/terraform-aws-modules/terraform-aws-eks/issues/1065))
+
+BUG FIXES:
+- The type of the output `cloudwatch_log_group_name` should be a string instead of a list of strings ([#1061](https://github.com/terraform-aws-modules/terraform-aws-eks/issues/1061))
+- Use splat syntax to avoid errors during destroy with an empty state ([#1041](https://github.com/terraform-aws-modules/terraform-aws-eks/issues/1041))
+- Fix cycle error during the destroy phase when we change workers order ([#1043](https://github.com/terraform-aws-modules/terraform-aws-eks/issues/1043))
+- Set IAM Path for `cluster_elb_sl_role_creation` IAM policy ([#1045](https://github.com/terraform-aws-modules/terraform-aws-eks/issues/1045))
+- Use the amazon `ImageOwnerAlias` for worker ami owner instead of owner id ([#1038](https://github.com/terraform-aws-modules/terraform-aws-eks/issues/1038))
+
+NOTES:
+- Managed Node Groups now support Launch Templates. The Launch Template it self is not managed by this module, so you have to create it by your self and pass it's id to this module. See docs and [`examples/launch_templates_with_managed_node_groups/`](https://github.com/terraform-aws-modules/terraform-aws-eks/tree/master/examples/launch_templates_with_managed_node_group) for more details.
+- The output `cloudwatch_log_group_name` was incorrectly returning the log group name as a list of strings. As a workaround, people were using `module.eks_cluster.cloudwatch_log_group_name[0]` but that was totally inconsistent with output name. Those users can now use `module.eks_cluster.cloudwatch_log_group_name` directly.
+- Keep in mind that changing the order of workers group is a destructive operation. All workers group are destroyed and recreated. If you want to do this safely, you should move then in state with `terraform state mv` until we manage workers groups as maps.
