Use my plugin to add the com.apple.ibooks.display-options.xml file.

It really goes in the META-INF folder (Sigil handles a prexisting com.apple.ibooks.display-options.xml file by showing it as being in the MISC folder), but you can't add files to the META-INF folder with the gui (manually adding it to the MISC folder will never work).

As for manually changing the package version, you can't do it. There's more to creating an EPUB3 than changing the package version to "3.0". And the package version is vital to many Sigil routines. That's why it can't be changed after the epub has been created.

Luckily there's an output plugin that can convert your EPUB2s to EPUB3s (though this is the first I've heard that embedded fonts will only work in iBooks with EPUB3s).

As to adding:

Code:

 prefix="rendition: http://www.idpf.org/vocab/rendition/# ibooks: http://vocabulary.itunes.apple.com/rdf/ibooks/vocabulary-extensions-1.0/"

to the package tag, I'm not experiencing any trouble doing so. As long as you're not trying to change the package version at the same time, I have no trouble adding all that extra Apple stuff to the tag.
