This works:
obabel molecules.sdf -O new.png -opng2 -m
producing new1.png, new2.png, etc.
On Windows, this also works:
obabel molecules.sdf -O new*.png -opng2
The new --split option has the same problem as -m.
The trouble is that PNGFormat is not quite a normal format because it has been adapted from a different purpose. PNG2Format is a normal format, so outputting to it does what is expected. I'll look to see if I can do something to make the more obvious command line work as expected.
