Dear @mtennekes when do you expect to send tmap-4.0 to CRAN? We have upgraded sits to work with tmap-4.0 as well as tmap-3.3. We are ready to submit our new version (1.5.2) to CRAN. We would prefer to use version 4.0, because its plots look much nicer than version 3.3. Thus, depending on your planes, we could delay sending the new version to CRAN until after tmap-4.0 is available. Any guidance?
