You might see a prompt about a new torrc from the package update. I chose to keep my existing version. There was no noticeable change once the service was back up.
Most relay operators won't want to replace their existing torrc, unless they want to start configuring their relay from scratch again.
The changes in the default torrc are aimed at new operators.
