Anchor v2 Hits Release Candidate: Solana's Main Framework Rebuilt on Pinocchio
The first release candidate of Anchor v2 is out — a complete rebuild of the dominant Solana program framework on Pinocchio. Solana Developers call for testing; the state is explicitly not production-ready yet.
What Happened
Anchor v2.0.0-rc.1 is out — the first release candidate of the new major version of Anchor, the most widely used framework for Solana programs. The core change: a complete rebuild on Pinocchio, Anza’s lean program foundation. Solana Developers called for testing over the weekend.
Why the Foundation Matters
Pinocchio is the library Anza recently used to rewrite the SPL token programs — considerably leaner on compute units than the classic base; background in P-Token: Anza’s SPL rewrite. With Anchor moving to the same foundation, practically every new Solana program inherits that efficiency — without developers leaving their familiar Anchor surface.
The status deserves clarity: a release candidate is not a production release. Teams running production programs test against the RC — but don’t migrate yet.
Note: This is reporting, not investment advice.
