An optional manifest key containing a string that defines which versions of
Chrome are able to install the extension. The value set for this string must be
a substring of an existing Chrome browser version string. Use a full version
number to specify a specific update to Chrome, or use the first number in the
string to specify a particular major version.

    {
      // ...
      "minimum_chrome_version": "126",
      // ...
    }

## Enforcement

### New Installs

In versions of Chrome older than the minimum version, the Chrome Web Store will
show a "Not compatible" message in place of the install button. Users on these
versions won't be able to install your extension.

### Existing Installs

Existing users of your extension won't receive updates when the
`minimum_chrome_version` is higher than their current browser version. This
happens silently so you should exercise caution and consider ways of letting
existing users know that they are no longer receiving updates.

> [!NOTE]
> **Note:** Enterprise users using [ephemeral mode](https://support.google.com/chrome/a/answer/3538894) are treated as new users each time they sign in. This means that if they are using a Chrome version lower than the `minimum_chrome_version`, your extension won't be installed.
