 ## 5.2.0 (Unreleased)
+
+BUG FIXES:
+
+* resource/aws_dx_connection: Convert `vlan_id` from [`TypeString`](https://developer.hashicorp.com/terraform/plugin/sdkv2/schemas/schema-types#typestring) to [`TypeInt`](https://developer.hashicorp.com/terraform/plugin/sdkv2/schemas/schema-types#typeint) in [Terraform state](https://developer.hashicorp.com/terraform/language/state) for existing resources. This fixes a regression introduced in [v5.1.0](https://github.com/hashicorp/terraform-provider-aws/blob/main/CHANGELOG.md#510-june--1-2023) causing `a number is required` errors ([#31735](https://github.com/hashicorp/terraform-provider-aws/issues/31735))
