The EPUB 3.1 revision is the first major revision of EPUB 3 standard. This revision to the EPUB core specifications will focus on consolidation, simplification, and dependency updates, as well as addition of a select set of new features.
The EPUB 3.1 revision is operating under a charter granted by the IDPF membership.
Work on the EPUB 3.1 revision is now underway. No public drafts have yet been produced.
Note: the first face-to-face meeting of the working group will be held in New York City on October 8-9, 2015.
