Nethack 3.6.1
I wasn’t really expecting to see this today: The NetHack dev team have gone and released an update. Mostly bugfixes, but this is NetHack so there also new features.
Sadly, they’re dropping support for some older platforms because they don’t have a current maintainer to manage the port. By older I mean things like “Atari” and “OS/2″. They’re also moving to ANSI C. Which is maybe the most significant change, since there’s source code in there that literally dates back to the early 80s, long before the C standard.
