Backward compatibility

The Nuance virtual extensions client and server components are designed to be backward compatible from the virtual server to the client end point. This means that you can run newer versions of the Nuance virtual extensions on the virtual server and they will work with older versions of the corresponding client-side components with the following caveats and recommendations:

*End-of-life: third party environments

Support for third party environments is only valid as long as they are supported by the corresponding vendor and might be subject to other restrictions. Please contact Nuance Technical Support for details. For more information, see the documentation delivered with the third party product and supporting Nuance documentation.

When standard support by the vendor has stopped, Nuance will continue support if an issue is specific to the Nuance solution, within the limitations of the vendor’s standard end-of-life and Nuance's policy. This means that issues that are a combination of the vendor’s component and the Nuance solution cannot be supported.
