epub version?
I have my Calibre configured to convert to epub 3 files.
However, when I buy books, they can be either epub 2 or epub 3.
Also, some of my books have adobe-hyphenate. I can tell because when I run the check in edit, I receive the following error:
Unexpected unknown property "adobe-hyphenate"
I'm guessing this is an extension to epub by Adobe.
Is there any easy way in Calibre to see what version of epub the book is? And to take this one step further, anyway to know what epub books have, I'm guessing, Adobe extended properties? Please correct me on this later point.
