May was a heavy month for Medplum, with 100+ commits from 20+ contributors and four patch releases — v5.1.10 through v5.1.13. Scheduling was the headline: the full appointment operation suite — $find, $hold, $book, $confirm, and $cancel — landed in Alpha. The Provider App also gained medication ordering components, order set import, and operation-based claim submission. On the enterprise side, a new data warehouse export features were enabled, and the platform team shipped passwordless magic-link login, AWS GuardDuty malware protection, and a round of OAuth2 spec-compliance fixes. All of this continues to drive forward our 2026 roadmap priorities.
