Thank you for the heads up.
But could you please provide guidance:
1. is this change ONLY for establishing new connections or
2. if Admin is already using the PayPal Commerce, eg since AbanteCart 1.3.3 which uses PayPal Commerce v. 1.0.0 does it need to be installed there also
Is the quick fix to be installed there? I see the version in quick fix is changing from 1.0.2 to 1.0.3, but neither AbanteCart 1.3.3 or 1.3.4 are using v 1.0.2 -- 1.3.3 is PP commerce 1.0.0 and 1.3.4 is 1.0.1
thanks in advance for more clarity.
