Changes in version 0.3.3 (2023-10-21)                  

Drop references to deprecated rgdal.

                 Changes in version 0.3.2 (2022-11-21)                  

BUG FIXES

1.  gh_covering would fail with minimal=TRUE for SpatialPointsDataFrame
    input, #30. Thanks @dshkol for the report and working example.

NOTES

1.  Fix compilation issue under -Wstrict-prototypes. Thanks CRAN team.

                 Changes in version 0.3.1 (2020-05-26)                  

NEW FEATURES

1.  gh_decode accepts and efficiently processes factor input by only
    decoding each level one time, #17. If you're likely to have a fair
    number of duplicate geohashes in your input, consider storing them
    as a factor for efficiency. In a few representative on 5-20M-size
    datasets, I saw roughly 5x speed-up from this approach; however, the
    time to convert from string to factor out-weighed this gain, so it's
    best deployed on data where the geohashes are stored as factor
    anyway.

BUG FIXES

1.  gh_decode errors early on non-ASCII input to prevent out-of-memory
    access, #19.

2.  Dependency upgrade of r-spatial to PROJ 6 revealed a test failure in
    geohashTools that has now been corrected, #23. Thanks @rsbivand for
    his diligence and proactivity in identifying the failure, to
    @Nowosad for providing helpful Docker images for testing, and
    @mdsumner for helpful comments.

3.  Input with longitude< -180 (which should be wrapped again around the
    Earth) was calculated incorrectly, #27.

NOTES

1.  Removed mockery from Suggests. It may later be restored, but
    currently it's not used.

                 Changes in version 0.3.0 (2019-10-03)                  

NEW FEATURES

1.  Complete overhaul of source code; C++ --> C & changed algorithm

BUG FIXES

1.  gh_neighbors incorrectly returned NA for geohashes whose first
    component is a boundary but whose higher components do indeed have
    neighbors, #14.

                        Changes in version 0.2.5                        

NEW FEATURES

1.  gh_covering works with input from sf. Thanks to @dshkol for the PR.

BUG FIXES

1.  gh_covering failed on input with missing proj4string, #13. Thanks
    @dshkol for the report.

                 Changes in version 0.2.4 (2019-08-26)                  

BUG FIXES

1.  CRAN submission again detected memory issues (accessing memory
    beyond which was declared for an array), reproduced & fixed for #6;
    the original fix also led to an uninitialized access error, #12.

2.  CRAN submission also detected a type mismatch error, #11.

                 Changes in version 0.2.2 (2019-08-21)                  

NEW FEATURES

1.  gh_covering for generating a covering of an input polygon in
    geohashes, #4.

BUG FIXES

1.  CRAN submission detected some memory issues in the C++ code which
    have now hopefully been fixed for #6.

2.  gh_to_spdf failed with duplicate inputs, #8. Duplicates are removed
    with warning.

3.  gh_neighbors('') failed, #9.
