I was working on a trigger that change all contacts owners once their parent account owner is changed. Before deploying it in production, I realized that this is already the actual behavior. Was it added in the recent Spring 16 release?

Note: An idea was posted on this purpose https://success.salesforce.com/ideaView?id=08730000000XrJFAA0 and I think that it hasn't added to the roadmap.
