BREAKING CHANGES: To add add SPOT support for MNG, the `instance_type` is now a list and renamed as `instance_types`. This will probably rebuild existing Managed Node Groups.

BREAKING CHANGES: The default root volume type is now `gp3` as it saves 20% and is more performant

NOTES: The EKS cluster can be provisioned with both private and public subnets. But Fargate only accepts private ones. This new variable allows to override the subnets to explicitly pass the private subnets to Fargate and work around that issue.

docs: Make it more obvious that `var.cluster_iam_role_name` will allow reusing an existing IAM Role for the cluster. (#1133)

improvement: Tags passed into worker groups should also be excluded from Launch Template tag specification (#1095)

fix: Don’t add empty Roles ARN in aws-auth configmap, specifically when no Fargate profiles are specified (#1096)

NOTES: Tags that are passed into `var.worker_groups_launch_template` or `var.worker_groups` now override tags passed in via `var.tags` for Autoscaling Groups only. This allow ASG Tags to be overwritten, so that `propagate_at_launch` can be tweaked for a particular key.

docs: Fix IRSA example when deploying cluster-autoscaler from the latest kubernetes/autoscaler helm repo (#1090)

chore: Use `#` for comments. It's the recommended way to start comment and it's more idiomatic (#1079)

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.

fix: The type of the output `cloudwatch_log_group_name` should be a string instead of a list of strings (#1061)

NOTES: 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.

feat: Add kubernetes standard labels to avoid manual mistakes on the managed `aws-auth` configmap (#989)
