+==== New PTP fast events REST API v2 available
+
+A new PTP fast events O-RAN v3 compliant REST API v2 is available.
+Now, you can develop PTP event consumer applications that receive host hardware PTP events directly from the PTP Operator managed pod via REST API.
+The PTP fast events REST API v1 will be deprecated in a future release.
+
+[NOTE]
+====
+In the link:https://orandownloadsweb.azurewebsites.net/download?id=344[_O-RAN O-Cloud Notification API Specification for Event Consumers 3.0_] specification, the resource is defined as a hierarchical path for the subsystem that produces the notifications.
+This implies that a subscription to a higher hierarchy path includes subscriptions for all lower hierarchy resources contained in the path.
+
+The PTP events REST API v2 does not support a global events subscription endpoint.
+You subscribe consumer applications to the various available event types separately.
