Scheduled

The Linea Foundation has announced a mandatory upgrade for all Linea Mainnet node operators. This upgrade introduces the Maru consensus client and will roll out across multiple network forks.

To maintain uninterrupted operation, all Linea node operators must run both the Linea consensus client (Maru) and an execution client of their choice (Geth or Besu).

We will begin upgrading infrastructure starting October 21, 2025 @14 UTC, and will complete all upgrade steps across the fork windows defined by Linea.

Updates will be posted here throughout the upgrade window.
