The ADAMANT Messenger team have implemented a Fair Delegate System, adding the Productivity of delegates to the calculation of Vote weight. Faster, more successful nodes that do not miss blocks will have a greater Vote Weight.

Another error that has been fixed, is the error that occurs when the nodes become stuck on block 4078586.

Attention! This update is mandatory for the installation of all nodes on the network, including those which do not include delegates. Changes come into force from block 4359464, approximately: August 3, 2018 (Friday). In another 2 days, all nodes on the version below 0.4.0 will be rejected by the network.
