For consistency with ggplot2, tm_polygons() now recognizes the fill argument instead of col.
Similarly, border.col is now col.
tmap now requires R 3.6 and above.
In view mode, hover is now independent from id (#851).
tm_vars() is a new function for multivariate scale (#819)
New family of functions tm_chart_*() to do charting (See ?tm_chart) (#581)
New vignettes available to explain how to upgrade your code to tmap v4
