Apr 1, 2026April 2026 (2026-04) monthly summary for openDAQ/openDAQ: Delivered notable feature improvements, stability enhancements, and performance optimizations that strengthen reliability and security across devices and clients. Key features delivered include Input Port Enhancements (batch-accepts via a single RPC and serialization of the input port public visibility flag) with corresponding bindings and tests; robustness improvements with daqTry guards around ModuleInfoImpl pointer casts; logging optimization to skip unchanged component statuses; a safety-first default operation mode set to SafeOperation for all devices; and client-server synchronization of operation mode so clients reflect the remote device's mode on connect. Business value: faster, quieter operation, safer startup, and improved consistency in distributed deployments. Technologies/skills demonstrated include C++, protocol version management, test-driven development, and bindings updates (Python/C) and changelog maintenance.

Mar 1, 2026March 2026 monthly summary for openDAQ/openDAQ focusing on business value, technical delivery, and cross-language bindings improvements: Key features delivered: - InputPort Visibility API: Introduced a public visibility attribute with getter/setter on InputPort, enabling client-side filtering and serialization that excludes non-public ports from client views. Includes de-serialization support, binding updates, tests, and changelog entries. Improves privacy controls and reduces payloads in client UIs. - Parquet Recorder Configurable Output Path: Added support to direct Parquet recorder output to a specified subdirectory, with robust path equality checks and updated tests to verify behavior. Improves data organization and reproducibility of recorded data. - C bindings Interface ID Getter: Added a getter to retrieve unique interface identifiers in the C bindings, improving SDK interaction, manageability, and integration with higher-level tooling. Major bugs fixed: - Pybind11 Memory Leak Fix for Python 3.14: Patch pybind11 to fix memory leaks in Python bindings for Python 3.14, with changelog updates and compatibility adjustments. Overall impact and accomplishments: - Strengthened data privacy and efficiency of client-facing data through new visibility controls and targeted serialization. - Improved SDK ergonomics and stability via interface identifiers in C bindings and Python binding fixes. - Enhanced data pipeline reliability and organization with configurable Parquet output paths and comprehensive tests. - Cross-language changes completed with rigorous testing, documentation updates, and changelog maintenance.
