Hi gurus !

/ic/api/process/v1/processes vs /bpm/api/4.0/processes

There are 2 different API endpoints and documentation sets for the process related functionality.
However, both specifications are not the same: they overlap but there are differences .
What is story behind ? Which one is leading? How will this change in the future? Which one to use ?

/ic/api/process/v1/processes
https://docs.oracle.com/en/cloud/paas/integration-cloud/rest-api/op-ic-api-process-v1-processes-get.html

/bpm/api/4.0/processes 
https://docs.oracle.com/en/cloud/paas/process-cloud/cprrb/op-processes-get.html

Thanks a lot

Tomas
