+==== New PTP fast events REST API version 2 available
+
+A new PTP fast events O-RAN Release 3 compliant REST API version 2 is available.
+Now, you can develop PTP event consumer applications that receive host hardware PTP events directly from the PTP Operator-managed pod.
+The PTP fast events REST API v1 will be deprecated in a future release.
+
+[NOTE]
+====
+In link:https://orandownloadsweb.azurewebsites.net/download?id=344[O-RAN O-Cloud Notification API Specification for Event Consumers 3.0], the resource is defined as a hierarchical path for the subsystem that produces the notifications.
+The PTP events REST API v2 does not have a global subscription for all lower hierarchy resources contained in the resource path.
+You subscribe consumer applications to the various available event types separately.
