Anza, Core Development Team of Solana: Recommends Solana Mainnet Validators to Use Agave 4.0
Anza, a core Solana development team, announced that it has recommended Solana mainnet validators upgrade to Agave 4.0. This release includes XDP for Turbine, TPU transaction ingestion exclusively over QUIC, faster replay stages, and a suite of feature-gated SIMD instructions set to activate during this cycle. Production environment results from large mainnet validators show Turbine retransmission latency has dropped from 600 ms to approximately 0.8 ms. Additionally, UDP-based transaction ingestion has been removed, making QUIC the sole transaction submission method; simple vote transactions now follow the same cost model as regular transactions. Features including p-token, Stake Program v5, SBPFv3 program support, pre-funded account creation, and BLS12-381 system calls will also be enabled during the 4.0 cycle.
