Mar 1, 2025March 2025 for fair-acc/gnuradio4 delivered targeted features and codebase improvements focused on performance tuning, readability, and developer velocity. Key outcomes include a new graph configuration capability (minimum buffer size) with end-to-end support (YAML parser reads minBufferSize and exporter persists it), and substantial codebase consistency refactors to improve maintainability. CI/build processes were standardized with ccache enabled to accelerate rebuilds. No major bugs were recorded as fixed this month; the work enhanced configurability, reliability, and the ease of future enhancements.
