What version/s of epub does calibre convert to?

I looked everywhere through the user manual and Google without success.

Thanks for replying. I want to know if the latest version converts to which version of EPUB2 or EPUB3?

Hmm, I can't think what else the answer "2" could mean in this context other than "epub2".

Sorry. I am new to this forum.

I didn't see the "2".

What I saw on my screen was a list of types of files not versions.

In any case, I'd like to know which version of EPUB2 and if/when it will convert to EPUB3?

Dear Kovid

Will you let me know which version of EPUB2 Calibre currently converts to?

Also, if or when will Calibre be able to convert to EPUB3?

Thanks

I'm afraid I have zero interest in the EPUB spec. So I have no idea what version of EPUB calibre produces. All I can say is that calibre produces files with the following two goals in mind:

1) Work on the widest variety of devices possible

2) Render as close to the input document as possible within the constraints of (1) and the user's conversion settings.

The EPUB spec(s) are largely irrelevant to both those goals.

That said the OPF inside the epub that calibre produces uses package version 2 which is the same as that used by the EPUB 2 spec.
