Changes in version 2.1.1 (2026-02-18)                  

Changed

  - Clarified printed message and documentation for the optional spatial
    coverage metric when s2 (>= 1.1.0) is not available.

Fixed

  - Fixed integer overflow warning with large datasets when using
    distance-based thinning with local kd-trees method. The issue was in
    the split() function used to assign points to grid cells. (#4)

                 Changes in version 2.1.0 (2025-11-25)                  

Added

  - Added is_lonlat() helper function to check for valid
    longitude/latitude ranges.
  - A warning is printed when coordinates lie outside the typical global
    longitude/latitude ranges.
  - summary() now allows to choose which trial to summarise using the
    trial argument.
  - Support for the priority parameter in the "distance" thinning
    method. When multiple candidate points have the same number of
    neighbors, the point with the lowest priority is removed (#1).
  - Support for NA values in the priority vector. These are treated as
    the lowest priority and trigger a warning.

Changed

  - The "grid" and "precision" methods now handle priority ties by
    randomly selecting among equally prioritized points.
  - Updated the vignette section on the priority parameter.
  - Added s2 (>= 1.1.0) to Suggests in the DESCRIPTION file.

Fixed

  - print() now reports both the number of trials run and returned (#3).
  - summary() no longer errors when s2 is missing or too old. Now
    spatial coverage is set to NA with a message (#3).

                 Changes in version 2.0.0 (2025-04-24)                  

Breaking changes. This version is backward-incompatible with earlier
versions of GeoThinneR.

Major changes

  - Introduced a new GeoThinned S3 class to represent thinning results.
    All calls to thin_points() now return a GeoThinned object instead of
    a list of logical vectors or data frames.
  - Added new helper methods for GeoThinned objects:
      - print() and summary() for inspection.
      - plot() for visual comparison of thinned vs. original data.
      - largest() to retrieve the trial with the most retained points.
      - largest_index() to get the index of the best trial.
      - get_trial() to access specific trials.
  - Redesigned thin_points() to return structured output and provide a
    more consistent user interface.
  - Output structure and behavior of all thinning methods has been
    updated for compatibility with the new object-oriented design.
  - We have improved the thinning algorithms by implementing two new
    modifications of the kd-tree method: local kd-trees (local_kd_tree)
    and restricted search (k_estimation).
  - The round and hashing method (round_hash) now is deprecated and has
    been removed from the package because of presenting lower accuracy
    than the other distance-based methods.
  - The thinning method argument method now includes the three main
    thinning strategies implemented in GeoThinneR for better
    understanding and usability. These are: "distance", "grid", and
    "precision".
  - The search_type argument has been included for distance-based
    thinning (method = "distance") to select between the search
    algorithms ("brute", "kd_tree", "local_kd_tree", and
    "k_estimation").
  - The n argument for the grid-based thinning (method = "grid") now
    lets you specify the number of points to retain per grid cell.

Minor changes

  - The long_col argument now is called lon_col for consistency with the
    lat_col argument.
  - The default column names (lon_col and `lat_col') have been changed
    from "decimalLongitude" and "decimalLatitude" to "lon" and "lat".
  - Improved documentation, error messages, and reproducibility behavior
    across all functions.
  - Updated the package vignette to reflect all changes.

                 Changes in version 1.1.0 (2024-10-03)                  

  - Removed non-CRAN dependency (rtree) and associated functions related
    to R-Trees structure thinning method (r_tree_thinning()).
  - Minor improvements to documentation.

                 Changes in version 1.0.0 (2024-09-02)                  

  - Initial release!
