4.2.6

- 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.

This release was made by the DAISY Consortium for the W3C. Many thanks to everyone who contributed and reported issues!

This EPUBCheck version is also available in the Maven Central Repository as [`org.w3c:epubcheck:4.2.6`](https://search.maven.org/artifact/org.w3c/epubcheck/4.2.6/jar).
