What's the difference between continuous integration and continuous delivery?

• Continuous deployment means the code CAN be released at any time, while continuous integration means it is released continuously.
• Continuous delivery means the code CAN be released at any time, while continuous integration means it is released continuously
• Continuous integration is just the practice of integrating code continuously. It doesn't necessarily mean that it can be released at any time like continuous delivery
• Continuous delivery and continuous integration are the same thing.
• Continuous integration doesn't mean that builds are available for release as continuous delivery implies
