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.

We have introduced a new Google Tag Gateway behavior. It allows you to enable first-party Google script loading by adding the Google Tag IDs for the Ion product.

• New frozen rule format available for Property Manager users: v2025-09-09.
• Now in the Origin Server behavior you can select Akamai Object Storage as an origin type when delivering your content using Property Manager. You can also choose Akamai Object Storage as the authentication method in the Origin Characteristics behavior.
• We enhance the Content Targeting Protection behavior to let you ignore the information from the X-Forwarded-For header for Geo Protection and IP Protection.
• We extend the Allow Delete, Allow PATCH, Allow POST, and Allow PUT behaviors to support Adaptive Media Delivery and Object Delivery.
• The Post Quantum Cryptography to Origin behavior is enhanced with a new PQC Keys in First ClientHello option. It lets you send the hybrid X25519MLKEM768 key in the first ClientHello.
• The adaptiveAcceleration behavior is now enhanced to avoid external resource calls. The source option uses hard-coded enum values, MPULSE and REAL_USER_MONITORING, instead of free-form strings.
• The HTTP/2 Edge to Origin option in the Origin Server behavior is incompatible with the WebSockets behavior. It will use HTTP/1.1 for the Edge to origin connection.

As part of the product life cycle management, the following Akamai Cloud Embed behaviors are decommissioned and no longer available:
