EPUB 3.2 has been approved by the Community Group

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
