BNB Chain ships v0.1.4 hotfix for BSC-Reth node operators
BNB Chain released a mandatory hotfix (v0.1.4) for BSC-Reth node operators on mainnet and testnet, requiring an upgrade and restart. The update is crucial ahead of the Jenner hardfork on December 8, 2026, and a planned migration to Reth-based clients by year-end. A potential security risk was acknowledged but deemed limited to BSC-Reth, with no immediate action required for users.
