Today I got this notification in Magento.
New Patch for PayPal Instant Payment Notification (IPN) Changes. Upgrade to 188.8.131.52 or SUPEE-8167 by June 30, 2017 to Avoid Service Disruptions – 6/13/2017 As of June 30, 2017, PayPal Instant Payment Notifications will no longer allow you to use HTTP to post messages back to PayPal for verification. To comply with these changes, all merchants using PayPal must upgrade to Community Edition 184.108.40.206 or apply the SUPEE-8167 patch. Updates must be in place by June 30, 2017 to avoid any service disruptions. The patch is available on the Community Edition Download Page (https://magento.com/tech-resources/download) and more information is available from PayPal at https://www.paypal-knowledge.com/infocenter/index?page=content&widgetview=true&id=FAQ1916&viewlocale=en_US
The link https://magento.com/tech-resources/download does not provide me with a link to download Magento 220.127.116.11. I'm also unable to find a download link for or a guide to applying patch SUPEE-8167.
How can I avoid service disruptions caused by the PayPal Instant Payment Notification (IPN) Changes?
