New Post: PayPal new SHA-256 certificate security

A new gateway release is now available for this issue.

I suggest installing it and testing it in the PayPal sandbox, which currently has the new changes applied.

If the old gateway is used, the IPN verification will throw an error to do with SSL/TLS connectivity. The new release resolves this.
