The development of EC-Earth4 has been started by the EC-Earth consortium in 2020. One of the major changes is that in EC-Earth4 ECMWF's OpenIFS will be used instead of IFS which will weaken the license restrictions and therefore it will be much easier for University communities to use the model for their research. Further development & tuning of EC-Earth4 will take place probably in 2023 & 2024.
