Preference settings for Type have changed
Previous versions of Illustrator allowed me to set my preferences for type to this:
Size/Leading = 0.5pts
Baseline shift = 0.5pts
But in Illustrator cc 2020 v24.2.2 it is no longer possible to do that. This is what I am getting:
Size/Leading = 1pt
Baseline shift = 1pt
It seems like 1pt is now the lowest you can go.
