The W3C EPUB 3 Community Group is pleased to announce their approval of EPUB 3.2 as a final community group report. We urge the Publishing Business Group to give us their blessing, so that we can publish. EPUB 3.2 is a minor revision of the EPUB 3 specification, which can be considered a successor to both EPUB 3.0.1 and EPUB 3.1. EPUB 3.1 did not receive wide adoption, and the Community Group decided to create EPUB 3.2 to be strongly backward-compatible with EPUB 3.0.1, while retaining many of the changes made in EPUB 3.1. I've previously described the motivations for creating EPUB 3.2 in a blog post at http://epubsecrets.com/why-specs-change-epub-3-2-and-the-evolution-of-the-ebook-ecosystem.php. EPUB 3.2 should not impact existing content or workflows. All valid EPUB 3.0.1 files will also be valid EPUB 3.2 files. The Community Group has written a summary of the changes at https://w3c.github.io/publ-epub-revision/epub32/spec/epub-changes.html. Some highlights include: 1. The specification has been reorganized, and sometimes rewritten, to be easier to read. 2. EPUB 3.2 is now based on undated references to HTML, CSS, and SVG, so that EPUB 3 can evolve as those specs evolve. 3. EPUB 3.2 now recommends that all publications conform to the EPUB Accessibility Specification. 4. epub:switch, epub:trigger, and bindings are deprecated, but still supported. 5. WOFF 2.0 fonts and SFNT fonts are now core media types. 6. Any value of the epub:type attribute is now allowed, although authors should still use the structural semantics vocabulary. Please let me know if you have any questions. For the EPUB 3 Community Group, Dave Cramer co-chair
