Previously the PagerDuty notification plug-in was hardwired to the US Events API v2 endpoint (events.pagerduty.com). Users with PagerDuty accounts in the EU data center had no way to direct notifications to events.eu.pagerduty.com without locally patching the plug-in.

The notification parameter dialog now offers a PagerDuty region selector with the two supported regions:

• US (events.pagerduty.com)
• EU (events.eu.pagerduty.com)

The same selection is exposed in the REST API on the PagerDuty plug-in parameters via the existing webhook_url field, which now accepts either the US or the EU endpoint URL.

Existing notification rules continue to work without manual intervention.
