AWS HealthOmics adds Nextflow version pinning
π¬ AWS HealthOmics now lets customers specify the Nextflow engine version at run time via the StartRun API, enabling explicit version pinning for controlled migration. Supported versions include 22.04, 23.10, 24.10, 25.10, and 26.04 via a new engine-settings parameter. This run-time override takes precedence over manifest.nextflowVersion, allowing testing across engine versions without changing workflow source. The feature is available in all AWS HealthOmics regions and supports HIPAA-eligible, production-regulated workflows.
