New Heading Parsing and org-vcard

[Jonas Damm]

Reading here: https://orgmode.org/Changes.html makes me believe breaking
changes in orgmode made the seemingly unmaintained org-vcard package not
work anymore.

I tried to modify the org-vcard package, but this is beyond my
capabillities.


So my question is: Can I maybe downgrade orgmode or restore the old
method of parsing some other way? I relied on org-vcard pretty
heavily. I hope I can find a way to keep using it.

Thanks!
