@dastrobu this isn't strictly needed, since the from: stanza in the dependency tells SwiftPM (or Xcode) to get resolve with this as a minimum version, up to the next major semantic version. So adding in updates to the README for each of the version increments wouldn't make using it as an example value in a real project any more or less effective.
