This is something that has intrigued me for awhile and didn't have a good answer to it, until today.

It seems that you can run the following command:

pip list --outdated

in your Python project command-line, and it will show you interesting information.

I did this for my cmd-clui project and got this:

Package          Version Latest Type
---------------- ------- ------ -----
iterm2           1.15    1.16   wheel
rich             3.0.5   4.0.0  wheel
setuptools       40.8.0  49.2.0 wheel
sortedcontainers 2.1.0   2.2.2  wheel

So, good to know.

This site had the answers (and some more) that I liked: Find outdated/updatable pip packages.
