This is bugfix release -- thanks to Sebastiaan and Tomas for finding a
nasty bug in the passive multiplication protocol. The NEWS file says:

Version 0.7.1, released on 2008-10-09
-------------------------------------

A major bug was fixed in the passive multiplication protocol in the
case where 2t + 1 != n. Unit tests were updated for Python 2.6.

* Players would do inconsistent recombination of shares in the passive
  multiplication protocol (Runtime.mul). This resulted in wrong
  answers being computed when 2t + 1 != n.

* Fixed unit tests on Python 2.6. The Bracha broadcast let the players
  send data to themselves by mistake, and for some reason this was not
  detected in earlier Python versions.

* Profiling information (from a run with --profile) is dumped in
  player-X.pstats and player-X.prof files for later analysis.

* Issue 57: Get rid of Runtime._shamir_share. The method was folded
  into Runtime.mul.

* Issue 69: The installation was simplified by including the ConfigObj
  library in the VIFF source. A system-wide installation of ConfigObj
  (if any) will be ignored.
