Dohyun Kim submitted an update to the
luamplib
package.
Version number: 2.20.0 2019-03-20 License type: gpl2
Summary description: Use LuaTeX’s built-in MetaPost interpreter
Announcement text: ----------------------------------------------------------------------
* huge changes, but mostly internal, so apparently not much difference from previous version. * 'mplibforcehmode' makes mplibcode typeset in horizontal mode. 'mplibnoforcehmode' reverts the setting. The latter is default. * 'mpliblegacybehavior{disable}' triggers a new mode of processing verbatimtex .. etex: along with btex .. etex, they will be processed sequentially one by one. Old behavior, being default, can be restored by declaring 'mpliblegacybehavior{enable}'. * Incidentally, verbatimtex .. etex in MP input files is honored from this version, save those that contain 'documentclass' or 'egin{document}' etc, which is totally ignored.
