I've been using Spring for a number of years, but have been a bit more DevOps/CI/CD and Cloud based over the last few years. I'm going to be leading a team into some new
Java endeavours and I'm looking forward to checking on the book - and hope that for someone that is well versed in Spring 3, and has experience with Spring 4 - what is new, what is improved and what should essentially should be "deprecated" from use. Does the book have a section that covers this, or is it just spread out throughout the book?
