Hello,

I have the question if AT&T still develops/maintains/updates UNIX. There is absolutely no information on this in the web so i thought this is the right place to ask.
I know that oracle makes Solaris which is from System V from original UNIX from bell labs. But does AT&T and bell labs still maintain it

No. The UNIX standard (not operational software, only standards) is maintained by the Open Group.
