Firedancer published a new testnet release, v0.906.40000. The update focuses on resilience, GUI improvements, and a small change to help leader targeting.
The release updates the agave submodule to v4.0.0-rc.0, improves resilience in edge cases, and refreshes the GUI. It also sends out the first shred early to aid leader targeting.
Testnet releases like this keep the validator client moving toward stronger stability and performance. Better resilience and leader targeting help harden the network path before wider deployment.
Validator operators testing Firedancer should review the changelog before upgrading testnet deployments. Mainnet users should treat this as a release signal, not a direct production rollout.
