I recently upgraded from 5.9 to 5.12.
My init.sage file loads/attaches a .sage file that I often use. In 5.9, that file was still attached when I started up a worksheet in the notebook. In 5.12, it is attached in the terminal, but when I then start open a worksheet in the notebook, it seems to be no longer attached since none of my functions are known any more and give a NameError when tried.
What can I do to fix this?
