This upgrade includes the EIP-7212 precompile to reduce gas costs of many smart wallet applications, supports Brotli batch compression for ~5-15% lower data availability costs, and improves the robustness of L1 data pricing. The upgrade also increases and hardcodes the max-sequencer-drift parameter, giving chain operators more time to respond to L1 node issues without facing a potential L2 chain halt.
