May 1, 2025May 2025 — Focused on stabilizing and refining timestep control under high-temperature conditions in MESAHub/mesa. Delivered Namelist-based options to cap the maximum timestep factor at high temperatures and to enforce a minimum log temperature, improving stability and predictability in thermal simulations. This change also restores previously available highT namelist options to support vetted simulation workflows (PR #815).

Jan 1, 2025January 2025: Focused on delivering higher-fidelity Stellar Rotation modeling in MESAHub/mesa. Implemented enhanced w_div_w_crit_roche calculation with reinterpretation of the sigmoid function and updated deformation fits based on recent research. Also removed obsolete rotational distortion controls to simplify configuration. These changes improve physical fidelity in Roche-lobe related rotation dynamics and reduce user configuration burden, enabling researchers to run more accurate simulations with less setup overhead.

Nov 1, 2024November 2024 Monthly Summary for MESAHub/mesa: Delivered Binary History Reporting Output Control to gate verbose processing output, enhancing diagnosability on demand while minimizing log noise. Implemented propagation of the new report flag through Fortran modules, ensuring verbose error messages are shown only when reporting is enabled. Applied targeted fixes to binary_history processing (binary_history.f90) and updated pgbinary_summary.f90 to ignore spec checks when reporting is disabled. Performed code cleanup by removing unused variables to improve maintainability and reduce technical debt. The changes improve reliability, observability, and developer productivity across the binary history workflow.
