Changes in version 1.1.1 (2026-03-27)                  

Bug Fixes

  - Fixed minor bugs related to parameter handling and data type
    coercion across various hedonic index calculation methods.
  - Added an explicit error catch to the plotting function to prevent
    execution when resting_points = TRUE is incorrectly passed.

Internal Improvements

  - Major Architectural Refactoring: Extracted the linear model fitting
    and prediction logic from individual hedonic methods into
    centralized, high-performance internal helpers (fit_hedonic_model
    and format_index_output)
  - Standardized internal data preparation and final index output
    formatting across Laspeyres, Paasche, Fisher, Time Dummy, and
    Repricing methods to guarantee strict consistency in output
    structures.
  - Refactoring maintains exact API compatibility with v1.1.0 while
    significantly improving code maintainability and speed
