Lastly, the CLI checks if a newer CLI version is available via the update API (see: rfc/update-api.json). If this is the case, it will print the latest CLI version instead of the output described above.
If the current version and latest version diverge more than one minor version, it will also show the latest CLI of the next minor version, and suggest a way to download it.
An example:
current CLI version: `2.3.2`
available CLI version with minor version `2.4.0`: `2.4.1`, `2.4.2`, `2.4.3`
latest CLI version: `2.5.0`
`constellation upgrade check` will show `2.5.0` as latest, and suggest that the next step in the upgrade process is `2.4.3`.

`constellation upgrade check` will show `2.5.0` as latest, and suggest that the next step in the upgrade process is `2.4.3`.
Since any CLI can only upgrade from one minor version below to its own version, we need to perform the upgrade to `2.4.3` before upgrading to `2.5.0`.
If there are still microservice updates needed with the current CLI, we need to prompt the user to first install those before continuing with the next minor release.
