• Explicitly add x and y scales limits to contourPlot2.
• Updated deprecated functions from scales package.
• Bugfix: avoid Inf duplication in contourPlot2 legend.
• Documentation: spell check and improvements.

• Dependency from other packages has been reviewed. RColorBrewer, dplyr and
  png are not required anymore.

  contourPlot() function. Geo processing is now performed by the required
  terra package.

• Bugs were fixed in the Pasquill stability class functions stabilityClass()
  and plotStabilityClass(). Furthermore, some working examples have been added.
• In contourPlot2(), deprecation of stat(level) and size of ggplot2()
  have been fixed.

The first version to be released on CRAN:

• The package is ready to be submitted to CRAN.
• Fixed many syntax errors, cleaned up code to try to comply with best practices.
• Fixed warnings in the documentation and added some working examples in
  some functions.
• Added some tests.
• Added a sample dataset stMeteo with hourly values of wind speed, wind
  direction, temperature, global radiation, total cloud cover and stability class.
• Renamed NEWS to NEWS.md.
• Updated README file.

• Trying to fix issues with fonts in contourPlot2().
• Updated readme file and fixed some minor issues in the documentation.

• BREAKING CHANGE: in raster plots with contourPlot2 (tile = TRUE) intervals are closed on the
  left and open on the right. In previous versions it was the opposite. In this way an interval
  [0 - 1) does include values equal to 0 and does not include values equal to 1.
