Upgrade Angular version (now: 2.4.3 or 4.0.0-beta.3) following the best practice? : <p>Now that <a href="http://angularjs.blogspot.com.eg/2016/12/ok-let-me-explain-its-going-to-be.html" rel="noreferrer">Angular is following a Semantic Versioning</a>,  and <a href="http://angularjs.blogspot.com.eg/2016/12/angular-240-now-available.html" rel="noreferrer">Angular2.4.3 were released</a>, I'm a little confused here on what is the best practice when I upgrade to the next Angular version in existing project.</p>
