aovCompare

You can watch a quick demo of the tool here: https://www.youtube.com/watch?v=IMYlnivyHxI

This simple script takes two read nodes and compares the layers available in each to return any differences. I came up with this as an idea with I was working on a show with a tight deadline and CG that didn't have a locked down look dev. The renders had many, many AOVs and they kept changing with each version. I decided it would be a good exercise in Python to figure out a way to work out the differences with a script.

As well as displaying the result in a pop up message, I also print the result to the script editor so you can easily copy and paste it into an e-mail or IM.

To install it simply download this aovComapre.py and move it to wherever you keep your Python script and then add import aovCompare to your menu.py.
