Exam guide updates, please clarify.

Latest exam guide has some important updates, as far I am aware.

3.3 talks more about Cloud Run instead of App Engine, same as 4.3. So does this mean the emphasis is more on Cloud Run but not on the App Engine as per the latest guide? If so, is the Cloud Run covered enough as part of this course for the exam? Also a minor updates on 3.6 and 3.7 are also noticed, please shed some light on these variations. Just want to make sure the preparation is really precise and up to the expectations for this exam. This of course doesn’t mean that practice and calculative awareness with solid understanding is not a priority, I am sure we definitely get that from this course. 

Thanks in advance!
