| **IMPORTANT**  
**This release requires a protocol upgrade.**   
 This release contains a consensus protocol upgrade, which implements the following spec: [GitHub - algorandfoundation/specs at 85e6db1fdbdef00aa232c75199e10dc5fe9498f6](https://github.com/algorandfoundation/specs/tree/85e6db1fdbdef00aa232c75199e10dc5fe9498f6) |

# Highlights

- **Contract to contract:** Smart contracts can now call other smart contracts, using the new inner transaction type appl
- **State Proof keys:** online participants will now generate Post Quantum-secure Falcon keys when renewing online status. These keys will be used to generate Algorand State Proofs
- **Batch Verification:** nodes can now group signatures in batches for faster verification

# Important Note

Note: Users running a local consensus private network with vFuture may need to rebuild the local network when upgrading their MainNet node.
