Release notes for StarkGate v2.0.1

New Features

Permissionless Bridging - In StarkGate v2.0.1 any user can add any ERC-20 token to StarkGate using the enrollTokenBridge function.
Deposit with Message - This feature let's the user add an arbitrary message to a deposit. The receiving contract must implement the on_receive callback to process the message. It allows enhanced and flexible processing of fund transfers.

StarkGate Registry - a central contract in which all bridged tokens are registered, both tokens permissionlessly enrolled, and legacy bridged tokens.
StarkGate Manager - Manages the registry and token bridging actions (enroll etc.).

Migrated codebase from Cairo0 to Cairo.
initiate_withdraw was renamed to initiate_token_withdraw. (initiate_withdraw remains for backward compatibility).
Added token as a new field in deposit and withdraw API. Old format remains for backward compatibility in upgraded bridges.
Fees: a minimum fee is enforced in deposit and enroll transactions. User can use estimateDepositFeeWei and estimateEnrollmentFeeWei to gauge the right fee value.
Withdrawal Limit - When enabled on a particular token, withdrawals of that token are limited to a daily cap.
This feature is a security measure that may be applied in extreme cases. See appropriate documentation for more information on this.
