I have many wiki pages with links to pages in onenote like this:
[[onenote:///\\server\share\etc.&end]]
This would normally fire up onenote and open the page.
Now dokuwiki does not even see that this is a URL.
I would rather not go back to the previous version.
Nervermind. I found it. I accidentally found an article urlschemes.
https://www.dokuwiki.org/urlschemes that answered question.
