We’re preparing for a major client release that will upgrade the network from v0.40.x to v0.41.x. This upgrade is required for all node operators to ensure continued operation and optimal performance.
Key Dates:
- Testnet Upgrade Deadline: February 20, 2025
- Mainnet Upgrade Deadline: March 6, 2025
What You Need to Do:
- Upgrade Immediately: Node operators can upgrade to v0.41.x now and sync with the network. Nodes that are not upgraded by the deadlines will no longer sync with the network. Release v0.41.6 · FuelLabs/fuel-core · GitHub
- Re-Sync for Best Performance: This release includes database optimizations for API queries. While re-syncing from the genesis block is not mandatory, it is recommended for optimal performance.
- Update Configuration: To ensure proper connectivity:
- Use the
--bootstrap-nodes
configuration. - Do not use the legacy
--reserved-nodes
option.
Refer to the updated documentation for correct settings: Node Operator Guide for Mainnet and Testnet
Important Notes:
- Nodes still using
--reserved-nodes
will lose connection to the network once infrastructure changes are implemented. - Ensure that your setup aligns with these guidelines to avoid disruptions.
