Important Note

Due to the increase in connections, you will need to ensure that your open files limit is sufficient (i.e., ulimit -H -n is sufficiently large). We recommend setting this to greater than 5000.

Overview

This release contains enhancements to networking capabilities such as our transaction handling and relay connection limits. In addition, we are including telemetry enhancements to better monitor the performance of the network.

What's New

• Batch verify transactions for more efficient signature verification
• Introduce elastic rate limiter to manage congestion from noisy peers
• Increase max incoming connections limit
• Decrease max connections per IP
• Increase default gossip fanout for relays
• goal node status now additionally reports consensus voting progress
