Version 0.3.4 - https://dl.dropboxusercontent.com/u/67242472/nxt.zip

An anonymous hacker did us a favor and spammed with double-spending transactions. New version has a quick work-around to get rid of such transactions. Luckyly block validation code was OK and didn't let to include blocks with double-spending transactions into the chain.
