I wonder what bug fixes/new features this firmware has? Is there a good reason to install if you're not having any problems?
parsobarus,
I always tell my customers that if it isn't broke...don't fix it. While some firmware releases do offer updated features and fixes it is usually a good idea to hold off until a problem starts occurring or a year past the firmware release passes. Of course this is all merely advice you can update the unit if you wish to stay current :)
