o Major bugfixes: - Ignore the timestamps of INTRODUCE2 cells received by a hidden service. Previously, hidden services would check that the timestamp was within 30 minutes of their system clock, so that services could keep only INTRODUCE2 cells they had received in the last hour in their replay-detection cache. Bugfix on 0.2.1.6-alpha, when the v3 intro-point protocol (the first one which sent a timestamp field in the INTRODUCE2 cell) was introduced; fixes bug 3460.
