Yes you're right when saying that it is 0.4. And yes it updates to 0.7 automatically. You only need to manually update when you're using 0.3 since there was a breaking change and auto updating didn't work.
For your suggestions to wrap everything in a try catch:
I won't spend time on the current Updater since I am working on a highly improved version of the Updater which also implements a lot of logging. So the user would also be able to find issues on his own or send them to us.
