Make sure you switched to EPEL's tor packages if you used torproject's RPM repository in the past.
EPEL provides the latest tor version (currently 0.2.8.7 [2]), former torproject RPMs are no longer updated at all [1].
The migration to EPEL packages includes some manual steps, like filesystem permission fixing (EPEL uses another username for the tor system account).
