I downloaded and installed the new version (Lifetimer), copied my character, ancestors, "mod" portraits, and a couple of tile replacements (various missiles in brighter colors to make it easier for me, the player, to find them) to the new version (I don't think any of that is relevant, but mention it for completeness).
After that I started the game, changed settings to the ones I want (in particular full screen, although activating the grid and maximum night brightness (squinting is no fun...) might also be graphics related. Music off, and metric units, auto enter homestead off (the bug reported a long time ago about zooming in that way and returning to a tile to the side of the one used for leaving remained in 0.72.2)).
After changing the settings I then activated Quit, at which time the game hang for a minute or so until I gave up waiting and killed it. When starting again the settings appear to be as they'd been changed to (haven't actually loaded my character), which is why I consider it a minor issue.
When changing the setting the music turned off immediately, while changing to full screen mode didn't take effect (and my suspicion is that the hanging is caused by the game trying to exit from full screen mode while actually still in windowed, although that's just a guess.
I haven't tried to revert and repeat, but I'm prepared to play around with things (including re-installation) if desired.
