[tor-commits] [metrics-web/master] Make ExoneraTor Beta the new default.
commit becc1f24af8d149c6c4a9e5223b7f0f4d4731695
Author: Karsten Loesing <karsten.loesing@xxxxxxx>
Date: Thu Mar 8 14:29:47 2012 +0100
Make ExoneraTor Beta the new default.
Two major changes:
- Results include IP addresses from exit lists, too.
- It's not required anymore to specify an exact timestamp, but a date is
enough.
