Hi Arbitrum fam 👋
We have a new Nitro release! 🚀 With this, Nitro nodes now support RPC queries with the "safe" and "finalized" block numbers. This release also includes various bug fixes and improvements. While this release isn't tied to a consensus upgrade, please upgrade when possible. 🛸

🎉 This new version 2.0.10 is meant to enable our protocols and developers to have a clear understanding on the state of block finality in Nitro, similar to Ethereum.

Release notes here: https://github.com/OffchainLabs/nitro/releases/tag/v2.0.10
Docker Hub: https://hub.docker.com/layers/offchainlabs/nitro-node/v2.0.10-73224e3/images/sha256-e132ff6837f96a36b14975e8227d462260c5e1fbfaafaed8ba69433b6cb290df?context=explore
