Changes in version 0.1.1 (2026-01-29)                  

  - Added the fit_2d_ld() function to fit the landscape for 1D data
    using the MVKE algorithm and simple integration.
  - Applied the log trick for the kernel calculation for better handling
    of small values.
  - Debug:
      - Changed the function form of find_eqs() according to the new
        setting of the MVKE() function; added linear_interp to
        sim_vf_options.
      - Fixed a typo in the fit_2d_vf() function.
      - The parameter na_action in fit_2d_vf() was not effective for
        method = "MVKE" in the previous version. Now it is fixed. The
        vector_position parameter is now also effective for method =
        "MVKE".
      - For MVKE(), the Gaussian kernel was used despite the user
        specifying an exponential kernel. This has been fixed and the
        default was changed to Gaussian.

                 Changes in version 0.1.0 (2023-02-10)                  

  - Initial release.
