Release v1.6.0

This release aims to support fast finality, a mechanism to finalize PoS chains originally developed by BSC. To enable this, we've added BLS public key registration functionality to the StakeManager contract. The spec are as follows:

• Only the validator owner is permitted to register and update the BLS public key.
• Duplicate key registration is not allowed.
  • In the case of an update, the previously registered key information remains unchanged. Users are not allowed to register a new key if it matches any previously registered key.
