note the two new fixes are in 0.2.2.7-alpha too

Changes in version 0.2.2.7-alpha - 2010-01-19

  o Major features (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.

    - When choosing which cells to relay first, relays can now favor

      circuits that have been quiet recently, to provide lower latency

      for low-volume circuits. By default, relays enable or disable this

    - New options for SafeLogging to allow scrubbing only log messages

      generated while acting as a relay.

    - Ship the bridges spec file in the tarball too.

    - Avoid a mad rush at the beginning of each month when each client

      rotates half of its guards. Instead we spread the rotation out

      throughout the month, but we still avoid leaving a precise timestamp

      in the state file about when we first picked the guard. Improves

      over the behavior introduced in 0.1.2.17.

  o Minor bugfixes (compiling):

    - Fix compilation on OS X 10.3, which has a stub mlockall() but
