In the category of rather minor, I had one small issue with the 10.5.2 update. After my MacBook Pro rebooted, my num lock and caps lock green lights stayed lit even though num lock and caps lock weren’t on. If I hit the keys so the lights go off, then num lock and caps lock come on. Very weird. I haven’t rebooted again to see if that fixes the issue.
If your interested in some of the updates, here’s a link:
