To all NULS community members:

On 4th December 2019, The NULS mainnet will release V2.2.0. In this version, the new / modified functions are as follows:

1.Optimize transaction broadcasting and connection strategies between consensus nodes, and strengthen network stability;

2. Fix some minor bugs and improved the performance of the main network.

This is a compulsory upgrade. 80% of the consensus nodes will be upgraded to the latest version and continue to generate 10,000 blocks before switching to the new protocol.

As this upgrade involves protocol updates, it will effectively improve the stability of the main network. Please complete the upgrade of all main network nodes as soon as possible to avoid receiving unnecessary yellow cards due to changes in network connection rules.

Update method: manually download the latest version of node wallet package;
