The biggest change is the continuation of moving media related metadata into the attachment itself in the media library, rather than storing it in the post. When you edit the response properties, they will go directly into the attachment data.
In a future version, I hope to continue with that to add better displaying of photos. Right now, the title of the photo is not showing, only, because it is using the built in gallery to generate the photos, the caption, which maps to the summary property. I will release a future version that shows the title if the caption is not set, as well as some other related fixes.
There is always more to do. Being as this was a major change, I wanted to let it sit for a little while before I released another version.
Thank you, David
