Post-4.1.0 changes

 * There will be no more publicly available
   binary 4.0.x releases (they will be reserved
   to the paying customers)
 * Use Erlang 27.3 image for the latest toolchain
   binary package. 27.2 is not latest and was not
   used intentionally
 * 4.2.x alphas must be cleaned up correctly
