Speaking for myself in Rust, I blindly update everything and fix what's broken. My projects tend to have substantial test suites, so if the compiler thinks it's fine and the tests think it's fine, it's probably fine. Sometimes it isn't fine, of course. Those cases fortunately are few enough and not damaging enough that this approach hasn't been that problematic thus far.
