Description of changes:
Updated pragmatic routing logic on the eHealth Exchange Hub to expand the scenarios in which messages are routed through the Hub.

Administrative utility to better support FHIR configuration on the eHealth Exchange Hub.

These changes will be applied to the eHealth Exchange Hub PRODUCTION environments as outlined above.

We do not anticipate any other service interruptions in PRODUCTION during the maintenance event; Real-time routing of messages through the Hub will be unaffected.

eHealth Exchange staff will monitor during the upgrade window to address any questions or concerns.

The eHealth Exchange Hub team has implemented a recurring weekly scheduled maintenance window each Thursday evening at 5:00pm ET for all non-urgent events.  The duration of each maintenance event will be determined by the respective changes for each event, and details will be communicated out to all Participants at least 48 hours prior to the event.  If there are no changes for any given week, then the maintenance event will not occur, and no notice will be sent. Also please note that Operating System and similar updates that do not require a service outage, and do not require changes to the application layer, will be performed during this scheduled maintenance window without specific notice due to their frequent and routine nature.
