**June 6, 2022**

### [](#minimum-mule-version-2)Minimum Mule Version

**Mule 4.1.0**

**October 8, 2020**

### [](#minimum-mule-version-3)Minimum Mule Version

### [](#fixed-issues-4)Fixed issues

The policy deployment fails when the CORS policy is applied to an API whose HTTP Listener configuration is deployed in a Mule domain, and that API uses Mule runtime engine v4.1.x. This is because both the domain and the policy export the same internal package.

### [](#new-features-and-enhancements-2)New Features and Enhancements

- The CORS policy now supports an **value in the `Origins` and `Headers` fields. An** signifies that there are no restrictions in the origin and header fields of the API request.

    [https://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html#sec4.2](https://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html#sec4.2).
