Changelog

New frozen rule format available for Property Manager users: v2026-02-16.

Cloud Certificate Manager certificates are now supported on both the Standard TLS and Enhanced TLS networks. Previously limited to the Enhanced TLS network, you can now select third-party CCM certificates when creating edge hostnames on the Standard TLS network in Property Manager.

• We introduce a new version of the Enforce mTLS Settings behavior in Limited Availability.
  • Now the Client Certificate Authentication options are included in the new version of the behavior.
  • Therefore we introduce the new version of the Client Certificate match condition.
  • We rename the existing mTLS Settings Enforcement rule template to mTLS Client Certificate Authentication, and the template includes the new options.
• The Post Quantum Cryptography Client to Edge and Post Quantum Cryptography to Origin behaviors are now compatible with FIPS 140. We also remind you that only for some users we support:
  • Enhanced TLS and Standard TLS in the Post Quantum Cryptography Client to Edge behavior.
  • Enhanced TLS in Post Quantum Cryptography to Origin.
    Contact your Akamai representative to check your options.
• The Error on First Byte Timeout and HTTP Error Response Codes options in the Origin Health Detection behavior are now in General Availability.
• We update the list of the networkTypeValues in the userNetwork match condition adding the HOSTED value.
• Now the FIPS mode - origin behavior ensures Federal Information Process Standards (FIPS) 140-3 compliance for a connection to an origin server, instead of FIPS 140-2.

• The Google Tag Gateway behavior is now available in General Availability. Note that before you use it, we ask you to acknowledge the mandatory legal disclaimer.
• New frozen rule format available for Property Manager users: v2026-01-09.

• The Post Quantum Cryptography Client to Edge behavior is compatible with the HTTP/3 behavior.
• We updated the list of the supported networks in the userNetwork match condition, removing BRIGHT_HOUSE and DION, and adding DOCOMO, DOCOMOBUSINESS, GTT. KDDI, OPTAGE, OPTUS, and SOFTBANK.
• We introduce a new Localhost Loopback Protection behavior that allows you to secure the requests on localhost.

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 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.
