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.
