Solana Changelog: September 3, 2026

What happened

Firedancer adopts three RPC calls and advances ARM support, while three mainnet feature gates and new Agave, Web3.js, and Solana Kit versions land. Firedancer has adopted three new RPC calls - getSlotLeader, getSlotLeaders, and getLeaderSchedule WTM - All three methods are part of the Solana RPC spec .

This discussion touches current issues with the Solana toolchain, the purpose of the runtime and the already ongoing work to have a better developer experience. Agave now disallows private or local addresses from being called by the TPU vote service , the TPU forwards service , and Votor WTM - The network addresses passed onto these services were too broad.

This narrows the scope of what these are by eliminating private and local addresses from ever being passed. A proposal was made on Agave to create a separate thread for shred recovery that is decoupled from the shred ingestion WTM - Decoupling recovery from shred ingestion ensures that recovery doesn’t block any shred ingestion that is taking place. Changing it to a class-based allocator allows for more well-defined memory lookup, which means faster operations and better performance.
