Nitro v3.11.4 fixes RPC bugs and boosts Arbitrum node stability Keep Arbitrum One and Nova running reliably with this maintenance update

Offchain Labs has released Nitro v3.11.4, a maintenance update for Arbitrum node operators. The software applies to Arbitrum One and Nova and is focused on stability and routine improvements rather than a major protocol change. The release notes highlight RPC bug fixes and adjustments aimed at stateexecution performance. These changes are mainly relevant for infrastructure providers, indexers, validators, and applications that depend on reliable node behavior. The update reflects the kind of ongoing maintenance needed as Layer 2 networks mature. According to the article, Nitro v3.11.4 is a narrower release and should not be treated as a broader network overhaul.
