What difference api.versionsFrom('...@...')
vs api.versionsFrom('...version...')
Ex: api.versionsFrom('METEOR@1.0');
vs api.versionsFrom('1.2.0.2');
From the docs:
meteorRelease String or Array of Strings
Specification of a release: track@version. Just ‘version’ (e.g. “0.9.0”) is sufficient if using the default release track METEOR. Can be an array of specifications.
