Hello, I am running Sage 6.4.1. Using the notebook interface, attaching files does not work as the files contents are not reloaded automatically. It just shows me the previous variable values.
echo foo.py > "x=2"
attach foo.py
x
2
echo foo.py > "x=4"
x
2
As you can see the value of x isn't updated to 4. I can confirm that attach works as intended on the terminal, just the notebook interface is broken.
