Do I have to update iPhoto with an upgrade to Snow Leopard or can I leave it as version 9.2.1 safely ?

I have an iPhoto Library of over 70,000 images and there have been a couple of times where some weird stuff has happened and I lost photos. I want to take advantage of a system update but have not updated iPhoto since 9.2.1 for fear of the whole thing crashing.
