Simon, I have tested an R-4.0.0 (i.e. R version 4.0.0 alpha (2020-04-01 r78130) with my two packages (nleqslv and geigen) and all my private tests. I have not found any problems with checking and testing these packages. (I used Apple clang and Coudert's gfortran 8.2)
The only issue I have encountered is: The R GUI hangs when I click "What's New In This Version" in the Help menu item.
