Repository for EPUB 3 Revisions in W3C

EPUBCheck Needs Your Help!

The W3C is raising money to fund further development of EPUBCheck, so that it can support EPUB 3.2. Please contribute if you can. Thank you!

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.

To participate in this revision, please join the EPUB 3 Community Group.
