Scheduled

We are upgrading Base Sepolia nodes to v0.15.0. During the maintenance window, brief interruptions to RPC availability may occur. This release contains mandatory client updates and requires node operators to migrate to base-node-reth and base-consensus by April 20th to maintain consensus compatibility.
