Platform domains (e.g. dev-site.pantheon.io) are now created for all sites, even if the site is part of an organization that has a custom domain. Previously, a site would start with dev-site.yoursite.io, it now starts with both dev-site.yoursite.io and dev-site.pantheon.io.
Code archives created using the Backups tool on the Test and Live environments now reflect the state of the codebase for the most recent deploy on the environment. You’ll no longer have to search for tags when restoring codebase.
We released a suite of tools comprised of Quicksilver Platform Hooks, a new release of our Terminus command-line interface, a new YAML-based project configuration interface, and broad compatibility with SAML for centralized authentication.
