v0.4.0

Highlights

• Added PostgreSQL and multi-instance deployment support, Prometheus metrics, managed native updates, and release-driven container images.
• Improved provider/model catalog administration, request logs, system settings, enterprise identity sources, and usage attribution.
• Hardened authentication, production bootstrap, trusted proxy handling, admin protections, provider compatibility, and frontend validation.

Release artifacts
