Hi,
the tor 0.4.5.x end of live versions are still on the recommended versions list:
https://consensus-health.torproject.org/#recommendedversions
consensus client-versions 0.4.5.6, 0.4.5.7, 0.4.5.8, 0.4.5.9, 0.4.5.10, 0.4.5.11, 0.4.5.12, 0.4.5.14, 0.4.5.15, 0.4.5.16, 0.4.7.7, 0.4.7.8, 0.4.7.10, 0.4.7.11, 0.4.7.12, 0.4.7.13 server-versions 0.4.5.6, 0.4.5.7, 0.4.5.8, 0.4.5.9, 0.4.5.10, 0.4.5.11, 0.4.5.12, 0.4.5.14, 0.4.5.15, 0.4.5.16, 0.4.7.7, 0.4.7.8, 0.4.7.10, 0.4.7.11, 0.4.7.12, 0.4.7.13
it would probably be better to stop recommending tor versions a month before they reach their eol date so relay operators get to see a log entry and have some time to react.
kind regards, nusenu
