The Corona Image Editor has not been updated, so is on the old UI and processing. However what is new is that you no longer need the CIE; you can drag and drop the CXR into the VFB instead and continue working on it whether or not the original scene is loaded (previously, you had to "resume from file" for 1 pass to get the saved CXR active in the VFB, which as well as needing that minimal render pass also meant you did have to have the original scene loaded).
There are no plans to update the CIE in the near future, as when we do update it, there will be fundamental changes in how it works, so that will take more time (in quick terms of the bigger work needed, rather than have a copy of the VFB code that needs to be updated separately, it will share code with the VFB meaning we only have to update things in one place and both VFB and CIE update together).
