This release improves the clarity and consistency of property activation messaging in the Property Manager application and guides. We're clearly communicating stages of activation, so that you can track when a new property version is live for your traffic, and what remains in progress in the rest of the CDN network.

Default Domain Validation (DV) is ​Akamai​'s streamlined certificate management solution that onboards secure hostnames to the ​Akamai​ platform with minimal effort and zero certificate overhead.

We enhanced the Origin Health Detection behavior with the two new options:

• New frozen rule format available for Property Manager users: v2025-10-16 .
• We introduce a new behavior that allows caching the content on the commercial servers. See Allow Caching on Commercial Network.
• The Post Quantum Cryptography (PQC) to Origin behavior is now in General Availability.
• We enhance the Content Targeting Protection behavior with the dropdown list of the options for X-Forwarded-For within Geo Protection and the new names of the options in API Reference.

You can now set up new automated notifications to enhance certificate monitoring capabilities. Stay informed about critical certificate events through Control Center, email, or Slack channels, helping you proactively manage certificate lifecycles and minimize service disruptions.

The Content Provider Code behavior now lets you configure the property to use the default CP code. Every contract has its own default CP code, and you can apply it to any of the contract's property configurations.

We're pleased to introduce a new validation capability for Cloud Certificate Manager certificates in Limited Availability. Now you can now select third-party certificates when creating edge hostnames in Property Manager, providing streamlined hostname configuration and simplified certificate workflows integrated with your existing Property Manager properties.
