+Changes in version 0.2.1.23 - 2010-0?-??
+ o Major bugfixes (performance):
+ - We were selecting our guards uniformly at random, and then weighting
+ which of our guards we'd use uniformly at random. This imbalance
+ meant that Tor clients were severely limited on throughput (and
+ probably latency too) by the first hop in their circuit. Now we
+ select guards weighted by currently advertised bandwidth. We also
+ automatically discard guards picked using the old algorithm. Fixes
+ bug 1217; bugfix on 0.2.1.3-alpha. Found by Mike Perry.
