Yep, me too. I'm coming up from the reboot now as I type this on my PlayBook. I'm hoping it fixes the notification issues I've been having. It just wouldn't give me a visual notification on the main icon, but it would be there on the notification area icon.
Could be... But with such a small version number jump I would think it was just bug fixes. I haven't seen any changes yet, but I'm still waiting for some notifications.
