Oystehr v1.22 - April 24 2025

FHIR

• Subscription processing is now asynchronous. Instead of processing which subscription Zambdas should be invoked after a FHIR API request mutates data, the FHIR API now pushes that task onto a queue to be processed separately. This allows the FHIR API to respond faster to your requests and also improves the reliability of the subscription processing.
• For transaction requests, subscriptions are now processed only if and when the transaction succeeds.
• The FHIR search _has modifier now excludes deleted resources when searching for references. This means that if a resource is deleted, it will not be included in the results of a search using _has.

Lab

• The Lab Service now supports receiving unsolicited results.

IAM

• The M2M resource's description field is now optional.
