I’ve upgraded from stable PHP-4.3.0 to unstable PHP-5.0.0-dev. So far, everything seems to work just fine. I don’t expect things will stay that forever. I just thought I’d give it a shot for a while. I’ll probably go back to 4.3.0 within the next couple of days.
I also got my new Olympus D-550 camera to work under linux. You can just mount it like any other USB mass storage device. It’s pretty sweet. I like being able to view my images under Linux.
