dispatcher 4.0.11 download

I need to download dispatcher 4.0.11 for some testing purposes in one of our environment. I know there is a latest version 4.1.8 going on but I need 4.0.11.

I went to this link https://www.adobeaemcloud.com/content/companies/public/adobe/dispatcher/dispatcher.html but I see only 4.1.8

Thanks.
