Normally the firmware updates are important updates with fixes to a number of issues. Some of the issues are reported, but other minor issues and fixes may not be publicly listed. Updates can affect EXIF, lens performance, battery performance, color, or noise reduction to name a few. As a general rule, give it a few days or a week after initial release and then update the firmware. If there are issues - which is rare - they would be uncovered and fixed in the first few days.
Eric... thanks so much! No specific concerns---just general experiences from others who've done it and whether or not it created any new problems, given I've never done it with the 7D. Your feedback's so helpful! Thank you!
