Which action(s) must be taken for Salesforce updates?

Updates are automatic; nothing needs to be downloaded or installed is the correct action for Salesforce updates. Salesforce updates are a feature that allows the user to benefit from the latest features and functionality of the Salesforce platform without any hassle or interruption. Salesforce updates are delivered automatically to all orgs three times a year, in spring, summer, and winter. The user does not need to download or install anything to receive the updates, and the user’s data and customization are preserved and compatible with the updates. Updates do not require purchasing an updated license, because the user’s existing license covers the updates. Updates do not need to be downloaded with each release, because the updates are applied automatically to the user’s org.
