0.49.1 is what Pd shows. I compiled it myself, so maybe I'm using a
version where the most recent changes affect only macOS.
If you compiled yourself, then it shows 0.49.1 alright :)
It's not a bug, unless you say, that paths are not even working
relative to what [symbol .( shows. You haven't said that yet. You only
said, that it is not working relative to what [bang ( shows.
Oh, well, it does work yeah, but since what opens is the root of the HD, what we're dealing with in a way is actually a full path, not quite "relative". But yeah, it's relative to the root...
