Hello, Matt Price reported an issue[1] with new link syntax in Org 9.3. As a consequence, I had to modify it slightly.
Backslash-escaping was required for some closing bracket characters. Now, /every square bracket/ within the URI part of a bracket link must be escaped. I updated the manual and the ORG-NEWS file accordingly. Please let me know if there's something suspicious. Sorry for the inconvenience.
