Pantheon release notes

As part of our continued effort to protect sites on our platform, Pantheon now requires all sites on the platform to prove domain ownership via TXT records. This verification is required before Pantheon will accept traffic on a domain name for a given site. This change enhances security by preventing a malicious actor from bringing traffic to a newly created site on Pantheon using a domain that pointed to a since-deleted site on Pantheon.

Customers who find this protection overly burdensome can opt out of this requirement at the level of their Workspace by engaging with our support team to see if they qualify for an exemption. For more information, refer to this FAQ.

The integration between Pantheon and New Relic is being updated to ensure compatibility with the latest changes from New Relic. These updates will be seamless for most users, except for those who are using Quicksilver to interact with the New Relic API.

If you are using Quicksilver, particularly any of the three New Relic scripts in the quicksilver-examples repository, please update your scripts by June 20, 2024, to ensure continued functionality.

Action required: Get and store your user API key and update your scripts

The necessary updates are described in the README.md file for each script. The steps are:

1. Log in to the New Relic from your site dashboard.

2. Get a user key.

3. Store the user key using Terminus Secrets Manager plugin.

4. Update the script to the new version (don't forget to change the secret name as needed!).

5. Push your changes to your repo.

6. Test your scripts when you have a chance to ensure they are still working.

Our Support team is happy to help if you have any questions or need assistance.
