Solana Changelog Lists Firedancer RPC Support and ARM Validator Compatibility

Solana’s engineering changelog published on September 10, covering updates for September 3, lists three feature gates as active on mainnet alongside releases for several developer tools.

The update also reports that Firedancer adopted three RPC methods: getSlotLeader, getSlotLeaders, and getLeaderSchedule. Firedancer additionally added support for operating its validator client on ARM systems.

The changelog is a technical release summary rather than a statement on network performance or market activity. It identifies implementation and tooling changes across the Solana ecosystem.

Three feature gates listed on mainnet

The changelog identifies three active Solana mainnet feature gates. One sets lamports per byte to 6,333. Another relaxes the post-execution minimum-balance check. The third upgrades the BPF Stake Program to version 5.1.0.

Feature gates are the mechanism referenced in the update for these mainnet changes. The supplied changelog summary does not provide additional implementation details or expected effects for the listed gates.

Firedancer expands RPC and hardware support

Firedancer adopted getSlotLeader, getSlotLeaders, and getLeaderSchedule RPC calls, according to the changelog. These methods are included in the update as part of the client’s ongoing development.

The release notes also state that Firedancer can run its validator client on ARM systems. This extends the hardware architecture support identified in the changelog, without establishing how widely the capability has been deployed.

Developer releases accompany the network updates

The changelog lists new releases for Agave, Solana Web3.js, Solana Kit, and other Solana developer tools. The update groups client, software development kit, and tooling releases with the mainnet feature-gate status.
