New Features

• CA whitelist
• AMOP authentication
• Event log pushing
• Start new groups without restarting the node

Update

• Support Channel Message v2 protocol
• Support to configure node address with domain names
• Increase max contract binary size limit to 256KB
• Output more detailed log for transaction exceptions
• Rename SDK certificate file names generated by build_chain.sh to sdk.crt and sdk.key
• Adjust some code structure for better performance
• Decrease memory footprint

Fix
