Mainnet Upgrade to v0.33
Scheduled Maintenance Report for Hedera
Completed
Completed: The Hedera mainnet update has been completed successfully!

Earlier this month, we deployed an improved gossip algorithm to Mainnet, which reduced the average time to finality. We have also observed periodic spikes in time to finality. With our strong commitment to stability and performance, and out of an abundance of caution, we will temporarily switch back to the previous gossip algorithm.
