EPUBCheck v4.2.6

EPUBCheck version 4.2.6 is now available.

Release Notes

This is the latest production-ready release of EPUBCheck. It provides complete support for checking conformance to the EPUB 3.2 family of specifications.

Version 4.2.6 is a maintenance release, which reverts two checks recently introduced in v4.2.5. In this newer version:

• the role property can now refine creator, contributor, and publisher properties more than once
  
• Media Overlays no longer have to match the reading order of the associated Content Documents

Reverting these checks is a proactive adoption of the rules that will be relaxed in EPUB 3.3, as the stricter checks recently introduced were problematic to some users.
