Welcome, Dear Ibrahim,
Thanks for reaching PayTabs out on our Developers Community. My Name is Osama El-Hamahmy the technical support team and I will be looking into this post and following up with you.
Regarding your inquiry, the latest version is 2.2.0 as on GitHub, and for integration using the CS-Cart plugin kindly follow the instructions in our solution article How to integrate your CS-Cart platform with your PayTabs account?
What is the latest integration with CS-Cart? and who I can integrate with my account?
