PhotInfo 4.10.0 became available about 20 days ago and I forgot to write a post, sorry.
The main new feature is the Action Extension of PhotInfo:
on iOS 8 it’s possible to see the main exif info from the Photos app or from other apps using the PhotInfo extension.
Moreover, there are some bugs fixed (iPhone 6 display support, MeteringMode on 64 bit devices).
