 ## 5.2.0 (Unreleased)
 
+FEATURES:
+
+* **New Data Source:** `aws_ecr_pull_through_cache_rule` ([#31696](https://github.com/hashicorp/terraform-provider-aws/issues/31696))
+
 ENHANCEMENTS:
 
 * resource/aws_redshiftserverless_workgroup: Additional supported values for `config_parameter.parameter_key` ([#31747](https://github.com/hashicorp/terraform-provider-aws/issues/31747))
 
 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))
+* resource/aws_redshiftserverless_namespace: Fix perpetual `iam_roles` diffs when the namespace contains a workgroup ([#31749](https://github.com/hashicorp/terraform-provider-aws/issues/31749))
 * resource/aws_redshiftserverless_workgroup: Change `config_parameter` from `TypeList` to `TypeSet` as order is not significant ([#31747](https://github.com/hashicorp/terraform-provider-aws/issues/31747))
 * resource/aws_redshiftserverless_workgroup: Fix `ValidationException: Can't update multiple configurations at the same time` errors ([#31747](https://github.com/hashicorp/terraform-provider-aws/issues/31747))
