June 2025 monthly summary for lf-lang/lingua-franca focused on improving configuration clarity for the Enclave reactor. The primary deliverable was making the stop_time parameter explicit for the s1 reactor, setting it to 5 seconds to remove dependence on implicit defaults. This enhances determinism during deployment, reduces misconfiguration risk, and improves maintainability and auditability of reactor configuration. No new user-facing features were shipped this month; the impact is a more robust, predictable configuration baseline and clearer code intent.

March 2025: Focused on expanding Python target test coverage in Lingua Franca, delivering a comprehensive Python test suite and standardized naming to improve readability and maintainability. The work increases reliability of the Python target and reduces risk for future changes.

December 2024: Completed stability and compatibility improvements across lf-lang/lingua-franca and lf-lang/reactor-c. Focused on aligning the reactor-c submodule to a stable revision to resolve downstream segmentation issues and ensure compatibility with Python code generation; stabilizing Python reaction generator by correcting segmentation in codegen, adjusting Python version handling in CMake, and preventing memory leaks; and enhancing the tracing subsystem by fixing calloc usage for trace buffers to prevent build-time and runtime issues. The changes reduced segmentation faults and memory-related bugs, improving reliability for downstream users and CI pipelines.
