  • improve resetting (base) plots; add reset = FALSE in a call to plot to enable adding to plots that have a legend

  • st_read, st_sf and st_sfc gain a parameter check_ring_dir (default: FALSE) that checks ring directions and corrects to: exterior counter clockwise, holes clockwise, when seen from above.

version 0.4-1

  • restore 3.3.0 and c++11 requirement

  • st_write now writes time always as UTC, since GDAL does not have a mechanism to define local timezones other than "unknown" or "local"
