Firedancer published testnet release v0.905.40007. The update includes an agave submodule bump and a fix for slightly underpacked blocks.
The release updates the agave submodule to v4.0.0-beta.7. It also fixes a bug that caused slightly underpacked blocks on testnet.
Even testnet releases matter because they shape validator performance and client stability ahead of broader deployment. Small fixes like this help harden the path toward more efficient block production.
Validator operators and contributors should review the changelog and compare behavior against prior builds. Mainnet-beta users should stay on the appropriate stable track and avoid testnet-only binaries.
