The library lags behind from the exif standard.
As as a result tags like PhotographicSensitivity, SensitivityType and possibly others are not correctly handled.
If the library is no longer maintained, please note this on the main page!
libexif hasn't had a release lately because there haven't patches submitted recently, presumably because no-one misses those features. Like most Open Source projects, libexif is maintained by volunteers and driven by the needs of its users as expressed through bug reports and patches. If you have need for better support for these tags or find their handling buggy, feel free to submit a patch or open a bug report with details!

I see. Yes, in general works fine, but Apple now uses these latest tags and they show up with empty names and the value is in numeric instead of textual one.
In what form do you prefer the patch? I think in this case only the exif-tag.h/c need to be changed. I might try to modify it and post them here. Will this be ok?

A patch (unified diff format is best) is preferred over posting the complete modified file since it's easier to see what has changed, especially if the original file has changed compared to the version you originally modified. But free free to attach the entire file if you can't easily make a patch.
