 ## 5.46.0 (Unreleased)
 
+NOTES:
+
+* provider: When using YAML or JSON documents, such as in `template_body` of `aws_cloudformation_stack`, CRLF was previously treated as different from LF but these are now treated as equivalent in many situations ([#14270](https://github.com/hashicorp/terraform-provider-aws/issues/14270))
+
 ENHANCEMENTS:
 
-* resource/serverless_cache: Add `minimum` attribute in `cache_usage_limits.data_storage` and `cache_usage_limits.ecpu_per_second` ([#36766](https://github.com/hashicorp/terraform-provider-aws/issues/36766))
+* resource/aws_cloudfront_origin_access_control: Add `lambda` and `mediapackagev2` as valid values for `origin_access_control_origin_type` ([#34362](https://github.com/hashicorp/terraform-provider-aws/issues/34362))
+* resource/aws_elasticache_serverless_cache: Add `minimum` attribute in `cache_usage_limits.data_storage` and `cache_usage_limits.ecpu_per_second` ([#36766](https://github.com/hashicorp/terraform-provider-aws/issues/36766))

 * resource/aws_ce_anomaly_monitor: Change `monitor_dimension` to [ForceNew](https://developer.hashicorp.com/terraform/plugin/sdkv2/schemas/schema-behaviors#forcenew) ([#36773](https://github.com/hashicorp/terraform-provider-aws/issues/36773))

+* resource/aws_cloudformation_stack: CRLF line endings in `template_body` no longer cause erroneous diffs ([#14270](https://github.com/hashicorp/terraform-provider-aws/issues/14270))
