o Security fixes: - Don't attach new streams to old rendezvous circuits after SIGNAL NEWNYM. Previously, we would keep using an existing rendezvous circuit if it remained open (i.e. if it were kept open by a long-lived stream or if a new stream were attached to it before Tor could notice that it was old and no longer in use and close it). Bugfix on 0.1.1.15-rc; fixes bug 3375.
