Hi there, I am wondering if transaction feature is available in self-hosting. If so, could you explain how to enable transaction?

Transaction support requires the transaction-bundles feature flag to be enabled on your project. Contact Medplum to enable this feature.

It seems like transaction feature is still in beta as well... do you happen to know when this will be officially released? https://www.medplum.com/docs/fhir-datastore/fhir-batch-requests#batches-vs-transactions
