Apr 1, 2025April 2025 highlights for apache/nifi-minifi-cpp: Delivered substantive OPC UA enhancements including node ID handling improvements, multiple certificate paths for trusted servers, and integration tests; upgraded the OPC UA library to 1.4.10. Consolidated logger initialization to a single instance per processor, improving resource management. Cleaned Build/CI: removed Apache RAT, separated static analysis into dedicated jobs, and added a Link Time Optimization (LTO) option to boost performance. Added option to reload parameter values from providers on MiNiFi C++ restart. Enabled NiFi State Manager API for Python processors with new Docker images and Python code to manage state across triggers; updated tests and docs. Fixed startup path resolution by reapplying the current working directory at startup. Impact: more reliable deployments, faster CI, better performance, robust state handling, and improved OPC UA capabilities.
