v0.11.0

What's Changed

• GPU acceleration for ZK proof verification, Switch-and-Squash (SnS), and re-randomisation
• tfhe-rs upgraded to v1.5 across the coprocessor
• Decryption ACL checks in the KMS Connector
• New Operator Staking system with ERC4626-based contracts, rewards, and audit remediations
• Confidential Tokens Registry and ERC7984 upgradeable wrapper contracts
• Dependence-chain processing in the coprocessor scheduler for better parallelism
• Host-listener poller mode as an alternative to WebSocket-based event listening
• Delegated user decryption test coverage in the E2E test suite

Migration Notes

• ebytesxxx removal: ebytes64/ebytes128/ebytes256 types are no longer supported
• tfhe-rs v1.5: Coprocessor FHE keys and serialized ciphertexts should be generally compatible
• GPU workers: new GPU backends are opt-in; existing CPU-only deployments remain the main supported architecture for now
