# Changelog
## 2025-05-19 - 19.3.2 - fix(SmartCertManager)
Preserve certificate manager update callback during route updates
- Modify test cases (test.fix-verification.ts, test.route-callback-simple.ts, test.route-update-callback.node.ts) to verify that the updateRoutesCallback is preserved upon route updates.
- Ensure that a new certificate manager created during updateRoutes correctly sets the update callback.
- Expose getState() in certificate-manager for reliable state retrieval.
## 2025-05-19 - 19.3.1 - fix(certificates)
Update static-route certificate metadata for ACME challenges
