I received a notice from PayPal stating they were upgrading their IPN security certificates:
"Over the course of 2015 and 2016, PayPal will be working towards upgrading various SSL certificates. The changes include upgrading the following:
The version of the VeriSign Trusted Root Certificate used to establish secure connections to PayPal.
The signing algorithm of certificates (from SHA-1 to SHA-256)"
Is there any documentation that states which SHA standards the Odoo PayPal integration uses?
