The next revision of EPUB 3 will be EPUB 3.2, which seeks to update EPUB 3.1 to make a successor that is compatible with EPUB 3.0.1 (i.e., that reverts the package document version number change introduced in 3.1).
Creators of EPUB content are advised not to implement 3.1, but to continue to create content compatible with EPUB 3.0.1 until work on EPUB 3.2 is complete.
