Solana client Agave 4.0 has officially released the upgrade to mainnet validators

Foresight News reported that the core development team of Solana, Anza, posted on Twitter announcing that Agave 4.0 has officially been pushed for upgrade to mainnet validators. This version brings multiple performance improvements, including significantly reduced network transmission latency, unified transaction submission using the QUIC protocol, and several on-chain modifications that unlock more block capacity, laying the foundation for Solana to pursue higher throughput.

Main updates include: after introducing XDP technology, Turbine retransmission latency dropped from 600ms to approximately 0.8ms, establishing the basis for advancing 100 million compute unit blocks; transaction submissions now exclusively support QUIC, removing UDP entry points; replay phase speeds have been improved through asynchronous optimization; vote transactions no longer use the static CU cost model, releasing more block capacity. Additionally, various features will be activated during this version cycle, including p-token (releasing about 13% of block capacity), Stake Program v5 (minimum staking threshold increased from 1 lamport to 1 SOL), SBPFv3 program support, and BLS12-381 system calls.
