If a Reason header is present on an incoming CANCEL request, it will now be copied onto any corresponding outbound CANCEL request on the linked SIP leg. Additionally, when a feature creates a new outbound CANCEL request with Reason header, the header will now be correctly included when the message is sent. (STLSIP-1301)

The Diameter Ro Resource Adaptor has been updated to the 3.1.0.x release series, enabling AVP version downgrade/upgrade between Rel 12 and older versions. The Ro Resource Adaptor can now be configured with a SLEE API version that is different to the "wire" protocol version for the OCS. Downgrading from Rel 12 is supported as far back as Rel 8.13.0. For further information refer to Diameter Resource Adaptors Changelog.

In previous releases general 3rd Party Registration functionality was only available as part of Sentinel VoLTE and Sentinel IP-SM-GW applications. As of this release it is available in Sentinel SIP. For further information refer to Sentinel Registrar Overview and Concepts
