Solana’s November 5, 2026, developer changelog reported tooling and validator work, not a single network upgrade. The developers said a Rolldown change cut an internal JavaScript SDK build benchmark from about two seconds to almost zero. That result applies to the specified build workflow, not to app loading times or transaction throughput.
The changelog also cited work on the Agave validator client, Firedancer leader handover, Anchor, RPC tools and local development tools. Its references do not show that every validator has deployed the changes or that planned network features have passed activation checks.
