According to Odaily, Ethereum developers have decided to postpone the public testnet upgrade timeline following the discovery of a new consensus bug in Pectra Devnet 5, which affected the Nethermind client. The Nethermind team has addressed the bug, caused by BLS precompile optimization, ensuring it will not impact the launch of Devnet 6. Developers plan to revisit the testnet upgrade schedule in the upcoming ACD meeting next week.
Additionally, the meeting highlighted a security vulnerability affecting the Geth client, which could impact Ethereum's peer-to-peer layer and Layer-2 scaling solutions. Nodes running Geth version 1.14 and above are advised to update to the latest version immediately.
The Pectra upgrade schedule is as follows:
- Week of February 3: Launch of Devnet 6
- February 6 (Thursday): Next ACD meeting to decide on Holesky and Sepolia testnet upgrade timelines
- February 10-11 (Monday or Tuesday): Official announcement of testnet upgrades
- Around February 19: Holesky testnet upgrade
- February 20: Developer meeting to determine Ethereum mainnet upgrade timing
- Around February 26: Sepolia testnet upgrade (planned approximately one week after Holesky upgrade)
- February 27-28: Release of the final version of the mainnet upgrade
- Mid-March: Ethereum mainnet upgrade
