There is a new accurate projection for world maps ► Equal Earth.
I know its proj4 but I can't add it in QGIS (see below). Does it need some kind of QGIS update?
This projection has been added to the
5.2.0. version of PROJ.4.
If you go in QGIS to Help>>About, you'll see that it uses an earlier version of PROJ.4
