Not sure if this is the place to ask this or if I need to open another thread for it. Now that Amazon has implement EPUB for Send-to-Kindle and will be discontinuing the MOBI format for that feature eventually,

(1) do I convert my files to EPUB2 or EPUB3? My EPUB output is currently set to EPUB2 as a default, but I'm wondering if I should set it to EPUB3 when I'm converting an older EPUB file or an AZW, AZW3, or MOBI file so that I can send it to my Kindle via email.

(2) is there a way to look at the metadata of an EPUB file in Calibre to check if it's EPUB2 or EPUB3? I can't seem to find how to do that.

Thank you.
