First of all, thank you for updating your book to Spring 5.
I don't see many books focused on Spring 5 certification.
So, thank you! This will help in my preparation.
I feel like this is a very broad question, and you can answer it however you like.
But, here's my context for the question.
You've written 2 other books on Spring certification.
Is the 2nd edition of "Pivotal Certified Professional Core Spring 5 Developer Exam" more challenging to write?
Is it a complete overhaul, or are there still items/chapters from the 1st edition?
