Export EPUB and HTML

Hi i searched on the internet and i found this link

“PKP is currently working on a project to automate the conversion of Microsoft Word documents into other formats, including XML, HTML, PDF, EPUB, etc. Keep an eye on our blog for updates.”

I want know that when can OJS users use this feature?

See https://pkp.sfu.ca/open-typesetting-stack/ and GitHub - pkp/ojs3-markup: markup plugin for OJS3.
