Yup all you'd need to do is (if you already have the auto-updater version currently installed from 0.8.0.4 you'd uninstall it and install the new one) install the new client via the full or online installer that will be released soon and you're good to go.
Initially the client will be set to auto-update which you can turn off by simply accessing the client control system tab and deselecting it as an option.
