Good to know about having to reboot to get the message, thanks for letting me know. Over here, restarting Unity works fine on both my desktop and Macbook. About your office PC, did you check this after downloading the beta update on your home PC? If so, I made a note about this in the beta update post of yesterday. The message will only appear once as it is a beta update. So that could explain why you did not get the message on your other PC. I will change that so you can download on both machines.
