No worries, I'm sorry I wasn't aware of the issue sooner! I've updated the article with gists - the part comparing error messages between 3.9 and 3.10 still uses images as they are compared side-by-side, but I've included a link to a notebook which walks through each of those comparisons too.

I also added 'alt text' describing the image just under the Better Error Messages header, I think you should be able to listen to that too correct?

Thanks and I hope this improves the article for you.
