o Minor bugfixes: - Reduce the log severity of the "Pluggable transport proxy does not provide any needed transports and will not be launched." message, since Tor Browser includes several ClientTransportPlugin lines in its torrc-defaults file, leading every Tor Browser user who looks at her logs to see these notices and wonder if they're dangerous. Resolves bug 13124; bugfix on 0.2.5.3-alpha.
