Docx4j 8.3.1 released

[jason]

docx4j 8.3.1 is now in Maven Central.

This is a minor release, but fixes an issue in 8.3.0 affecting those using 8.3.x with docx4j-ImportXHTML.

Other changes in Version 8.3.1

+ Concurrency fix in NamespacePrefixMapper (most obvious with MOXy); fixes #464

+ PDF via FO: Output hyphenate, language and country attributes to support hyphenation in PDF output

+ Move legacy PDF converter out of docx4j-core (to new module docx4j-legacy-service), so -core no longer requires Apache HttpComponents or Jackson

To use docx4j 8.3.1 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

Otherwise, see https://www.docx4java.org/downloads.html

Minimum supported Java version is 8.0. (docx4j 11.3.0, a JPMS modularised release for Java 11 users will follow in coming days. Please note Java 11 users can use docx4j 8.3.1 if they wish)
