Should I update?

I have managed to avoid updating the game since prior to the Marketplace update. Is the game in a stable enough position that I should update now before the major May update that's coming? Or should I keep my game in a pre-Marketplace state?

I do use mods and custom content, but I don't need any new ones at the moment, so they can hang in a frozen pre-patch state as well until I update. I would be concerned if there are still mod or cc related issues floating about.
