Pantheon release notes

WordPress 4.9.1 has been pushed to all WordPress site dashboards. This is a security release, and we suggest everyone upgrade immediately.

Over 200,000 sites are already on Pantheon's Global CDN, but if you still have sites pointing to the legacy, deprecated infrastructure, you can now see which sites need an upgrade from your User or Organization Dashboard. Find the required DNS information from the Domains / HTTPS tab on each site environment. Complete the upgrade as soon as possible, and let us know if you have any questions.

Global CDN now respects the no-store directive in the cache-control header.

On newly created sites, you are now directed to install your WordPress or Drupal CMS as the next step.

Drupal 8.4.2 has been pushed to all Drupal 8 site dashboards.
