Oxygen 3.8 RC 2 includes a single fix for the Google Maps element, which was using a deprecated API and stopped working on May 26th. In 3.8 RC 2, the Google Maps element will work as expected as long as you have a Google Maps Embed API key in "Google Maps API Key" field in Oxygen > Settings in the WordPress admin panel. To learn more about how to generate a Google Maps Embed API key, visit https://developers.google.com/maps/documentation/embed/get-api-key.
Existing users can download Oxygen 3.8 RC 2 in the customer portal.
