By default, from version 3.7 and above, your WordPress site will do an automatic update when a new security or minor update is released.

This means, that if you’re on WordPress 3.8.0 and version 3.8.1 is released your site will auto update itself. On the other hand, if WordPress 3.9 is released (a major version) by default you will have to update it manually.

However, the truth is that sometimes things don’t go as planned especially if you have heavily customized website with a millions of plugins. If this is a case we strongly suggest that you disable auto-updates for the core, themes, plugins and do all of the updates manually one by one! Looks time-consuming, well it is a hell of a lot better than having your clients website crashed.
