 ### Features Added
 
 - Expanded the set of acceptable values for environment variable `AZURE_TOKEN_CREDENTIALS` to allow for selection of a specific credential in the `DefaultAzureCredential` chain. The valid values now include any of the credential names available in the default chain (`VisualStudioCredential`, `VisualStudioCodeCredential`, `AzureCliCredential`, `AzurePowerShellCredential`, `AzureDeveloperCliCredential`, `EnvironmentCredential`, `WorkloadIdentityCredential`, `ManagedIdentityCredential`, `InteractiveBrowserCredential`, or `BrokerAuthenticationCredential`.) **Note:** `BrokerAuthenticationCredential` requires that the project include a reference to package Azure.Identity.Broker.
 
 - Re-introduced `VisualStudioCodeCredential` and included it in the `DefaultAzureCredential` authentication flow. This credential now supports Single Sign-On (SSO) through the authentication broker on Windows, macOS, and Linux using the Azure.Identity.Broker package.
 
-### Breaking Changes

 ### Bugs Fixed
 
 - `ManagedIdentityCredential` now retries 410 status responses for at least 70 seconds total duration as required by [Azure IMDS documentation](https://learn.microsoft.com/azure/virtual-machines/instance-metadata-service?tabs=windows#errors-and-debugging). Previously, 410 responses were retried with the same short exponential backoff as other status codes, resulting in insufficient retry duration ([#50724](https://github.com/Azure/azure-sdk-for-net/issues/50724)).
