az104

Normally the exam study guide https://query.prod.cms.rt.microsoft.com/cms/api/am/binary/RE4pCWy includes a list of changes but it doesn't appear so for AZ-104

You can see which areas has changed here https://docs.microsoft.com/en-us/certifications/resources/study-guide-az-104#detailed-exam-changes . You can compare the tasks in the skills in the Functional Groups with the previous version which is at the bottom of the page
