+### Added
+* New endpoint added `POST /ehr-resend/<conversationId>` which will re-request the GP Connect structured record, and
+  resend a newly generated EHRExtract to the requesting GP2GP system.
+  This endpoint can be used when the requesting system asks that the sending system resends the medical record
+  because of a temporary technical fault.

+  when a transfer hasn't been acknowledged by the requesting system for 8 days or more.
