Where to find latest update

I purchased a few months ago and just wondered what the upgrade process looks like. When a new version releases, should I expect an e-mail or is it distributed via other means? And lastly, what is the current latest version?

You will receive a new version automatically by email. The latest version is 3.3.1.

I have purchased personal license and version is 3.4.0 and yet i have not received any update in my email , Also I have sent an email but there is no reply from support team.
