Continuous delivery and Continuous deployment are not same

If you think continuous delivery and continuous deployment are same then you are wrong. There is a major difference between both,

In continuous delivery, I could be deploying constantly. It means I can deploy the version I want and each source control check-in will not deploy the latest version automatically.

In continuous deployment, I am deploying constantly. Each source control check-in will automatically deploy. As it always deploys the latest version of the code automatically for each source code check-in we should need very strong automation coverage when compare to continuous delivery.
