docx4j 8.1.5 is now in Maven Central. Thanks to those who contributed.
The driver for this release is to ensure the namespaces corresponding to prefixes w16 and w16cid are declared
when docx4j outputs a docx. Microsoft Word (following recent updates) has writes those prefixes to the mc:Ignorable attribute, and
it is unable to open a document if a prefix which appears in that attribute is not declared.
For further changes please see https://github.com/plutext/docx4j/blob/ ... ANGELOG.md
To use docx4j 8.1.5 via Maven, just add one and only one of docx4j-JAXB-Internal, docx4j-JAXB-MOXy,
or docx4j-JAXB-ReferenceImpl to your pom. https://search.maven.org/search?q=g:org.docx4j
