What's Changed

✨ Main Features

Keygen

Ability to trigger the key generation directly via the Gateway.

New User decryption share mechanism

PauserSet

A new PauserSet contract is available as a host and gateway contract used for the pausing mechanism.

Cleanup

Host and gateway contracts have been cleaned: - Unused offset has been removed from the decrypted result in public decryption. - Gateway check... functions have been replaced by non-reverting is... boolean getters. - contractsChainId field have been removed from user decryption request EIP712 struct. - New internal empty proxy contracts have been implemented. - Two gateway contracts have been renamed.
