January 2026 performance summary for lf-lang/lingua-franca and lf-lang/reactor-c. Focused on delivering trace plugin enhancements, build system improvements, and ROS2/CMake reliability. Highlights include dictionary-based trace-plugin property with tests and CI, federated build path relativization, dynamic trace plugin integration with modular CMake logic, and cross-repo build fixes that stabilize ROS2 C++ and coverage collection. These changes reduce build failures, accelerate federated builds, and simplify custom trace plugin workflows for users.

December 2025 monthly summary focusing on delivering the Tracing Plugin Build System Integration for lf-lang/reactor-c, with build system improvements, enhanced plugin extensibility, and foundational work enabling broader tracing adoption across components.

November 2025 — Lingua Franca (lf-lang/lingua-franca): Delivered substantial documentation improvements and CI automation to improve API discoverability and reduce maintenance costs. Implemented comprehensive docs quality upgrades across parameters, links, verbatim blocks, and comment parsing, backed by a focused set of commits. Added a CI script to detect Doxygen warnings, filtering false positives and surfacing only actionable issues. Key commits include: 081b70a40efcf5b58c521a90b5525271950b444b, 1b603c781513bc63e8ae82aa54e05984b37919e6, 576337b2440353dceeda91e790444da7c5716fc1, c03436be9f4f22a4dcd7f95422109ba45a8f9502, 03f3faf338f1d930579cce73321ef7dd1ce5f643, 4ac2d09575050943cc43676d5f43440da06633c5.

May 2025 monthly summary focusing on key platform stability and policy updates across lingua-franca and reactor-c, with emphasis on business value, test coverage, and robustness.

April 2025 monthly summary for lf-lang development. Focused on delivering robust features, improving scheduling reliability, and enhancing maintainability across two repositories (lf-lang/lingua-franca and lf-lang/reactor-c).

January 2025 monthly summary for lf-lang/lingua-franca. Delivered robust federated code-generation improvements and strengthened test coverage to improve reliability in distributed workflows. Key outcomes include cycle-free min-delay calculation, backward tracing of physical actions, and safeguards against stack overflows during compile-time evaluation.

November 2024: Delivered Scheduler Selection Simplification in lf-lang/lingua-franca by removing the deadline-based GEDF_NP logic, resulting in a simpler and more predictable scheduler decision path. Eliminated pickScheduler() and its helper hasDeadlines() in CGenerator.java to reduce dead code and maintenance burden, enabling easier future policy experimentation. Core commit: 9bd8dacdba9de15f22dd784e4b9077f01c2625f2. This work improves scheduling determinism, reduces risk of deadline-driven edge cases, and accelerates future enhancements.
