EPUBCheck v4.2.2
This is a production-ready release of EPUBCheck, which provides complete support for checking conformance to the EPUB 3.2 family of specifications.
Version 4.2.2 is a maintenance release which reverts the toc and page-list navigation order check to a mere WARNING (it was previously an ERROR), following the recent EPUB CG discussion. It also includes new translations, notably for Traditional Chinese (thank you @davidmaxlee!).
This release was made by the DAISY Consortium, for the W3C. Many thanks to everyone who contributed!
This EPUBCheck version is also available in the Maven Central Repository as org.w3c:epubcheck:4.2.2.
Tip: If you are running EPUBCheck on a 32bit JVM and it crashes and reports a StackOverflowError, try to increase the Java Thread Stack Size!
