Prepare a burndown list for teams upgrading to Asciidoctor 2
There are a long list of changes for asciidoctor 2: https://github.com/asciidoctor/asciidoctor/blob/master/CHANGELOG.adoc#200-2019-03-22---mojavelinux
This needs to be filtered for relevance to Asciidoctor.js and Antora, and expanded into useful documentation.
A first step might be to put the relevant portion of the changelog into an .adoc, mark the inappropriate ones, and write a paragraph or two for the appropriate ones.
