From OmiseGo, "Don't believe sites/links telling you to do something for $OMG airdrop or you will get scammed. There is nothing to do. Just wait."

This is mainly a bugfix release that corrects a problem with the return value of the low-level delegatecall function and removes some invalid warning messages.

This release contains several new features and bugfixes and also an important security fix: The ecrecover function can be forced to return invalid data, which can be used to bypass authentication in very special circumstances.
