The range of valid integers in scripts is extended to [-9223372036854775807, 9223372036854775807]. - The Heartbeat feature adds a new window to the real-time difficulty calculation. For miners using the value returned by the getblocktemplate RPC this is transparent and no change is required. For miners computing the value in the pool software the calculation needs to be updated. See https://e.cash/mining for more details. - The Avalanche Pre-Consensus feature is enabled. The nodes will start voting and reconcile transactions so they are finalized before being mined. See https://e.cash/blog/preconsensus-pr for more information on this new feature. - The Avalanche Staking Pre-Consensus feature is enabled. The nodes will start voting on the next staking reward winner, making sure the block template is selecting the same payout address across all miners. No change is required to the pool software.

To stay in sync with the network, node operators must update to version 0.32.x before the November 15, 2025 upgrade is activated.
