     1.7 +A major bug was fixed in the passive multiplication protocol in the
     1.8 +case where 2t + 1 != n.
     1.9 +
    1.10 +* Players would do inconsistent recombination of shares in the passive
    1.11 +  multiplication protocol (Runtime.mul). This resulted in wrong
    1.12 +  answers being computed when 2t + 1 != n.
    1.13 +
    1.14  * Fixed unit tests on Python 2.6. The Bracha broadcast let the players
    1.15    send data to themselves by mistake, and for some reason this was not
    1.16    detected in earlier Python versions.
