This update replaces the legacy "Monolithic Core" (MC1) firmware, which had been the standard since 2022. The OC2 architecture introduces a separation between secure control plane and data plane operations, effectively eliminating a class of race conditions that plagued earlier revisions.

Troubleshooting notes

• If device fails to initialize after upgrade: power-cycle, collect the new JSON diagnostics, and verify firmware handshake logs for race-condition indicators.
• For continued unexpected resets: enable extended power-management tracing and compare pre/post-update traces to isolate negotiation failures.

| Legacy Feature | Replacement in OC2 v1.0 | |----------------|--------------------------| | JSON-RPC on port 8080 | gRPC on port 50051 (TLS only) | | Modbus RTU (serial) | Modbus TCP with secure proxy | | Plaintext syslog | RFC 5424 over TLS (port 6514) | | Legacy jcac-set command | oc2-cli with JSON output | If device fails to initialize after upgrade: power-cycle,

Impact & Risk

• Expected benefits: improved uptime, reduced latency, fewer security incidents, easier debugging.
• Migration risk: minimal for current oc2-v0.9 users; systems using deprecated handshake must update clients.
• Rollback: safe; changes gated behind feature flags where feasible. Recommended to stage rollout and monitor traces.
