compare-master-to-stable.js script doesn't work properly after switch to 1.4

The output says that it compares master with 1.2.x (instead of 1.3.x). To be investigated / fixed.

The tag on the latest version is v1.4.0-beta.0. The prerelease tag ("beta") causes it to be excluded from the set of versions that's checked - see documentation for semver.

Specifically, semver.satisfies('1.4.0-beta.0','1.x') returns false:

One possible fix to ensure the most recent version is included:

function (tags) {
  var currentTag = tags[0];
  var major = currentTag.split('.')[0] + '.x';
  return tags.
    filter(function (ver) {
      return semver.satisfies(ver, major) || ver == currentTag;
    });
}

Closing since it seems fixed.
