Aug 1, 2025In August 2025, delivered a targeted security configuration fix for NVFlare provisioning. Corrected the Admin Startup Kit CONN_SECURITY retrieval to source from the admin participant rather than the server, ensuring consistent security configurations across provisioning flows. This reduces misconfiguration risk in admin startup kits and aligns with security policy requirements. Commit 0569814ccdd50147c9f3997998ed7e65f6d31001 accompanies the change and addresses issue #3595. Overall impact: improved reliability, security posture, and deployment consistency.
