When Atlas told me that my Tor node was running an "Outdated Tor version" I upgraded Tor on my node (Ubuntu 14.04 LTS, Trusty) system.
Atlas now tells me that my platform is "Tor 0.3.0.10 on Linux" (as I expected) but it is still saying 5 hours later that it is an "Outdated Tor version".
Have I missed something?
UPDATE: I note a message from Roger Dingledine on the tor-relays mailing list that suggests that this might be an issue with only one (on 5 August) of the three dir auth servers recommending 0.3.0.10. However it is now 22 August and they should all be updated.
