1. Security Fixes

• Fixed an issue where certain validation checks for enclave build artifacts were not consistently executed (JIRA: PROD-11281).

3. Known Issues

• When using an external load balancer configured with HTTP-based health checks on port 4445 (for example, GET /sys/v1/health or /health), the endpoint returns an HTTP 404 (Not Found) response starting from DSM version 5.2 (JIRA: RODE-580).
