BitcoinZ is constantly developing!
You can proceed with the update of your client versions. This is not a “hard” update that is required in order to be part of the BitcoinZ network, however it is highly recommended to update.
V2.07 includes :
– Security updates
– Insight Explorer update
– Testnet Blossom Rewind functionality & more.
Our next version will be the 2.1.0 and it is going to be a “must update”.
