We’re on a roll - EPUB 3.4 is coming

The Publishing Maintenance Working Group at W3C has been quietly working on yet another update for the EPUB3 standard, and we’re excited to share what we have been up to. Our goal is to not only maintain the EPUB standard, but do our best to keep it in line with the needs of industry, and this update does exactly that. Your existing books do not need to change, if they conform to previous EPUB versions, they will conform to EPUB 3.4.
