February 2025 monthly summary: Refined inplace-related overloads in pandas-stubs to ensure correct return types for in-place operations across core DataFrame methods (rename, fillna, replace, reset_index, dropna, sort_values, sort_index, interpolate, clip, where, mask). This improvement reduces incorrect type inferences and enhances static analysis workflows. Main commit: e5ce0f9f9d1f7ec913a39923139e9513ecdb305f (Simplify and fix overloads for methods with inplace parameter).
