ACTION MAY BE REQUIRED: Important merchant integration upgrade information.

[CKD Productions]

I'm sure a lot of our clients have received this email by now from PayPal. I have not been able to find any information on how (or if) this affects Magento. Is this going to impact Magento clients? If so, all versions? Thanks in advance. Content of email from PayPal follows:

We’re contacting our merchants with some important information in response to an industry-wide security upgrade which is not unique to PayPal. This change involves upgrading Secure Sockets Layer (SSL) certificates over the course of 2015 and 2016.

Because these changes are technical in nature, we advise that you consult with your partner, website vendor, or individuals responsible for your PayPal integration. They will be able to identify what, if any, changes are needed. If you do not have a technology team, we recommend you find one, and we can work with them to ensure you continue to process payments through your current integration with PayPal.

Full technical details can be found in our Merchant Security Syst​em Upgrade Guide. In addition, our2015-2016 SSL Certificate Change microsite contains a schedule of our service upgrade plan.

Questions can be directed to our Merchant Technical Services team on our Technical Support website. Click here for more information.

Thanks for your patience as we continue to improve our services.
