We're not providing backwards compatibility 👀

For example, that bearings (";") is not valid anymore because we're expecting a list now.

Now we're expecting something like this 👀

"routeOptions": {
		"baseUrl": "https://api.mapbox.com",
		"user": "mapbox",
		"profile": "driving-traffic",
		"coordinates": [
			[-77.043331, 38.853108],

}

For annotations is going to happen the same and for whatever field we converted from String to List. It's not a "problem" because we can bump to a major version but it'd be great avoiding breaking SemVer.
