In case someone is interested to add target='_blank'
to external links only.
You can enable blackfriday.hrefTargetBlank=true
.
[blackfriday]
plainIDAnchors = true
hrefTargetBlank = true
Sadly, shortcode ref/relref link can no longer be used as the link will be generated with target='_blank'
as well.
You can use markdown reference link.
