• Added start in epoch components
• Arwen now runs in a separate process, monitored by the arwen driver inside the node
• Removed the second broadcast of the block body after the consensus has been achieved
• Changed the data field type in the transaction data structure
• Removed an exploit that could affect peer id - public key mapping on all peers
• Fixed termui metrics
• Removed a bug by implementing a white list mechanism. The bug appeared whenever a debit transaction was added in the same block with a credit transaction affecting the same address and the credit transaction could not have been executed without first executing the debit transaction.
