2 questions, though.
1. Previously, the type of the link was "thisfile", now it's "custom-id" and also, the leading hash is removed from the link. Let's consider the [[#about][About]] example once again. Previously, I was given ("thisfile" . "#about") and I changed this to ("thisfile" . "About"), which then worked like a charm. Now, I'm given ("custom-id" . "about"), which I don't know how I should translate. Neither of ("custom-id" . "About") or ("id" . "About") work. What should it be?
BTW, there's a line (require 'ord-id) in org-open-at-point function in master. Probably, it's a typo (should be (require 'org-id))
2. When those fixes will be available in MELPA?
