- Amendment: fixDelegateV1_1 - In DelegateSet, disallow invalid PermissionValues like 0, and transaction values when the transaction's amendment is not enabled. Acts as if the transaction doesn't exist, which is the same thing older versions without the amendment will do. - Payment burn/mint should disallow DEX currency exchange. - Support MPT for Payment burn/mint.
