Upgrade to 126.96.36.199 or Apply SUPEE-8167 – Latest PayPal IPN Upgrade Notification for Magento Merchants
If you’re a Magento merchant who has been using PayPal IPN (Instant Payment Notification) service, you have possibly received an email alerting you to upgrade to 188.8.131.52 or Apply SUPEE-8167 in order to avoid this service disruption.
This upgrade will last till the end of June, i.e. June 30, 2017. And, from June 30, 2017, PayPal IPN service will no longer permit merchants to utilize HTTP while posting messages back to PayPal for verification. As a merchant, you will only be allowed to use HTTPS for such postbacks.
If you’ve not made the essential changes, we urge you to do the followings before this service disruption starts affecting your Magento store:
• Enterprise Edition 184.108.40.206 or apply the SUPEE-8167 patch • Community Edition 220.127.116.11 or apply the SUPEE-8187 patch • Magento 2.0.15 when it becomes accessible (probably the next week of June)
Note: If you’re running Magento 2.1.x, there is no need of any update as all Magento 2.1.x versions already comply with this change.
