I am testing the v6 espescially the versioning
I had indeed some issue with latest version that would systematically remove the lightroom edits from the files (i.d: make all versions share the same development setting = all versions become the same)
So far it looks much better, I have only seen one strange xmp modification that I need to track down (not sure the versioning did it).
All the other XMP modification followed my settings so that I could change some value while retaining the development setting intact.
So that is really great.
However when I asked to cascade image details the development setting were then overwritten even though the help file says otherwise:
unless you consider development settings to be non-technical.Cascade Image Details; this will copy all non-technical and descriptive
metadata from XMP to all images in the set.
It is no more a big issue for me as with last version of photosupreme but if it is a bug it would be nice to correct it or update the documentation accordingly
