Restricting New Versions for Old Buyers

Message:
Dear Codester Support,

I would like to know if there is a way to prevent old purchasers of my software from downloading newly updated versions. I want to ensure that only new buyers, or those who purchase an upgrade, can access the latest version.

Does Codester provide any option to restrict downloads based on purchase date or implement an upgrade pricing model? If not, do you have any recommendations for handling this scenario?

Looking forward to your guidance.

Best regards,

Let me know if you want any modifications!

No, it's not allowed and we don't support such activity by authors. All buyers expect to receive all updates.
My recommendation is to forget about this whole idea..
