This is the first stable release in the 2.1.x series and includes the finalized changes for the upcoming Bhilai Hard Fork.
Note: This release contains some breaking changes to the database. Downgrading to previous versions requires re-syncing the chain from genesis. Please read the sections below carefully before upgrading.
Bhilai Hard Fork Preparation
- Includes all protocol changes specified in PIP-63.
- The Bhilai Hard Fork is not yet active. Activation parameters (such as fork block on mainnet) will be included in a follow-up release.
Database Format Change
- The internal database version has been upgraded from v8 to v9.
- This is a backward-incompatible change. After upgrading:
- Downgrading to older versions will require a full resync from genesis.
Chain Rewind Behavior
- Upon upgrade, nodes will enter a head-state missing state and will rewind several hundred blocks. This is expected behavior.
- If you operate a cluster of interconnected nodes:
- Upgrade them one at a time to allow rewound nodes to sync from peers that are still fully synced.
- This minimizes the risk of extended downtime during the upgrade process.
Gas Limit Adjustment
- The default block gas limit will be increased to 45 million.
- This is a non-hard-fork change and takes effect immediately upon deployment of this version.
⚠️ Validator Configuration Update (Mandatory)
If you are a validator upgrading to v2.1.x, you must check your config.toml file.
If the gaslimit field under the [miner] section is uncommented, it should be updated to the new value:
[miner]
gaslimit = 45000000If this section is not present or if gaslimit is commented, then you are all set. No actions needed from your end.
This change is required to support PIP-60.
Note: This release includes changes from EIP-7745. As a result, CPU usage may temporarily spike after a node restart due to log indexing. This is expected and should normalize once the indexing is complete.
