OCPI 2.2 is an important step forward. Nevertheless, the community is already looking ahead, because developments in this field are progressing rapidly. Responding to these developments remains important. OCPI continues to evolve.

In December 2019 the first design setup of OCPI 3.0 was published. Version 3.0 will contain major changes, mainly in the architecture. This will improve the efficiency of OCPI. Further developments and steps for OCPI 3.0 will be made via the participants in the new evRoaming foundation. We aim to have the first draft available by the end of 2020.
