THT: What is a squared annular “ring”? [duplicate]
$begingroup$
This question already has an answer here:
Square vs Round pad
4 answers
At least in KiCad, the footprints of through-hole pin headers have one squared annular “ring”, the other ones are round:
What does the square indicate?
(Also I’m wondering if there is perhaps a convention of connecting GND to it.)

At least for KiCad the answer is very simple. It is specified that way in the library convention: kicad-pcb.org/libraries/klc/F7.3 (Answer in comments as i can not create an answer to a duplicate question.) We are however slowly transitioning to using rounded rectangle pads instead of square ones. (Benefits: Better solder joint, more space for traces.)

It’s just a quick and easy way to distinguish which connector pad is pin 1.
Particularly when there is no silkscreen present or just when routing the PCB.

And there is not a convention of connecting ground to it! Don't even think that thought!

Of course there's a convention of connecting ground to it. It's just that there are also 17 other conventions.
