Concise monthly summary for 2025-01 focusing on key features delivered, major bugs fixed, impact, and technologies demonstrated. Highlights include feature work on two repositories: a) tidy3d introduced backward-compatible plotting support via HeatChargeSimulation.plot_heat_conductivity (deprecated; users encouraged to adopt the general plot_property API); b) tidy3d added a min_N parameter for semiconductor materials along with codebase hygiene improvements (import path refactors, docstring updates, and clarifying an analysis spec). In tidy3d-notebooks, a bug fix reconciled the charge modulator diagram by correcting the image path. Overall, these efforts improve usability, configurability, and reliability of visualizations and simulations, while reducing the long-term maintenance burden and facilitating migration to newer APIs.
