After that, the next file systems went up to 255 characters.
My first UNIX was Wang IN/ix, which was 14 characters. That was in the very late 80s. Not long afterwards for home use I got Coherent OS, that also had a max of 14.
Later was Slackware, seemed the sky was the limit.
But to be honest, I wish there was still a smaller file name limit, I usually keep my file names size small. But I know I am in a tiny minority when it comes to the size of the file name :)
Edit: Yes:

EDIT: Upon further reading, it appears MS did finally get rid of this restriction, but some 32-bit apps still don't play nice.
Some would even have configurable parameters.

"Wang also offers a UNIX System V.2-compatible operating system, IN/ix for the VS8000 series" and a footnote mentions that it's due in 1990
My Dad did some work with Wang 2200 systems, but by 1990 it had become clear that the IBM PC compatible was inevitable and he'd switched to Niakwa Basic instead of Wang systems for his customers (mostly running a bespoke small business payroll system).
