Now when you create a new site on Pantheon, you can select from one of four regions across the globe, including Australia, Canada, and the European Union. For more info see Pantheon Site Regions and Data Residency.
Pantheon now recommends A/AAAA records instead of CNAME records. This change is to reduce complexity, confusion, and address a few edge cases introduced with CNAMEs. For example, the use of an MX or TXT record prevents the use of a CNAME. If you are already using a CNAME you can continue to do so or you can update to A/AAAA records as shown on the dashboard.
An issue was fixed that improved the consistency of hourly cron runs.
WordPress 5.2.2 is available to apply as 1-click updates on Pantheon site dashboards. For more information, see https://wordpress.org/news/2019/06/wordpress-5-2-2-maintenance-release/.
