Update for Roadmap to Asciidoc3-3.1.1

Published: 2019-07-27

Here comes an update for the raodmap towards AsciiDoc3-3.1.1. Support of DocBook5.1 will be included as announced in our previous post.
Argparse will replace the deprecated optparse in a2x3.py - getopt (which is not deprecated) will remain in asciidoc3.py.
During our work on these enhancements we encountered one minor bug in a2x3.py when using option --dry-run. So everything takes up a little more time to implement, please be patient: AsciiDoc3-3.1.1 comes in the first ten days of Aug-19.
