One of my tor nodes was affected. I've upgraded openssl and changed keys.

Two questions:

Do I have to do something to get the old key blacklisted to make sure
that someone can't impersonate it?
(Old fingerprint: $C33ABC15B69DA274588CA1869CC1EE7B1DC11DAD)

Should I rename my node? It doesn't show up as named anymore because of
the key change.
