 ## Known Issues
 1. (Updated 09/18/2025) You may experience failures when using an S3-compatible storage solution. An updated AWS library may trigger authentication issues with some third-party storage solutions. As a result, you may experience errors when running plans and applies or when accessing Terraform state files. Refer to [issue 2960](https://github.com/aws/aws-sdk-go-v2/discussions/2960) on the AWS SDK GitHub issues page for more information. Please ensure your S3-compatible storage solution is fully updated. 
+2. (Updated 09/19/2025) The Terraform Enterprise API must include the value of the `x-tfe-version` header in its response. This header indicates the current version of Terraform Enterprise. Currently, the value of this header is absent.
 
 ## Deprecations
 1. Redis 6.0 will be officially deprecated as of the November release.
