  - Bugfixes
      - Found and fixed a few more little plotting bugs (thanks to John
        H. Lowry).
      - Made a few things more efficient.

                 Changes in version 4.1.1 (2024-04-17)                  

  - Bugfixes
      - Fixed a minor loop indexing error that threw an error if all
        centre types were not selected.

                 Changes in version 4.1.0 (2023-09-05)                  

  - Improvements
      - Inclusion of repaired and renamed function calc_cmd() that was
        previously CMD(). The change was to bring consistency across
        function naming.
      - Inclusion of repaired function plot_centres().
      - Renaming CF() to calc_cf() to bring consistency across function
        naming.
      - Renaming CF2PTS() to calc_cf2pts() to bring consistency across
        function naming.
      - Renaming mean_centre() to calc_mnc() to bring consistency across
        function naming.
      - Renaming median_centre() to calc_mdc() to bring consistency
        across function naming.
  - Bugfixes
      - Major clean-up and refresh of man pages for most functions.

                 Changes in version 4.0.1 (2023-08-29)                  

  - Improvements
      - Shortened title as required.
      - Updated package description.
      - Added necessary Rd-tags on man pages.
      - Moved cat() statements to warning() and message() formats.
      - Ensured that user environments are properly restored after
        functions exit.

                        Changes in version 4.0.0                        

  - Major Items
      - Resurrecting aspace from its current archived state by
        addressing flags and errors.
      - Functions no longer write .txt files but rather return list
        objects.
      - Global variables are eliminated to adhere to R guidelines.
      - Calculation output objects are consistently encoded.
      - Functions provide greater error-trapping to ensure valid inputs
        are provided.
      - Functions CMD() and plot_centres() are currently disabled due to
        issues. Hope to have them active again for the next version.
      - Eliminated reliance on 'shapefiles' package.
  - Improvements
      - Functions return consistently structured objects rather than
        writing them to the workspace.
  - Bugfixes
      - Updates and adjustments to manual pages.
  - Future Plans
      - Incorporate vector geographic data objects with package 'terra'.
      - Produce a generic plotting function, eliminating the need for
        multiple forms.
