Changes in version 0.9.2 (2022-09-23)                  

  - Bumped minimum R required version to 3.5 (sysdata.rda uses workspace
    format version 3)
  - Replaced testthat with tinytest for Unit Testing.
  - sgo_coordinates gained a couple of paramaters meant for geodetic
    coordinates.
  - Improved the speed of NGR conversions.
  - A little tidy-up of both code and documentation.

                 Changes in version 0.9.1 (2021-12-11)                  

  - Fixed: Now, when converting from 2D BNG to 3D BNG, the input is
    first converted
    to 3D by filling z with zeros. Previous versions just added zeros to
    the output.
  - Fixed: When converting from 2D to 3D coordinates with the same datum
    the z
    column was not being filled with zeroes.
  - Fixed: Points right on the upper boundaries of the OSTN grid are
    considered
    outside of the OSTN15 rectangle.
  - Fixed: Output text of the print function.
  - Improved slightly the speed of 3D calculations from/to BNG.
  - Improved some parts of sgo_transforms's documentation.

                 Changes in version 0.9.0 (2021-10-28)                  

  - Initial release on CRAN.
